1. IN DOOR AIR QUALITY
If you could see the air you breathe under a microscope, you might be in for a surprise. The air quality is much more
terrible than you may think. In fact, floating in indoor air is a "soup" of particles too small to be seen by your naked eye.
But it is large enough to cause problems. Visible dust makes up only 1% of all the particles in the air. The vast majority
of particles are microscopic.
How long the particles float in the air depends on their size. Relatively "heavy" dust particles (more than 5 microns)
tend to settle out of the air in 20 minutes or less. They form the dust that's easily wiped away on tables and other
surfaces. Middleweight particles (from 1 to 5 microns) may remain airborne for hours before falling out of the air.
Lightweight particles (less than 1 micron) can remain suspended permanently in the air. And particles sized less than 1
micron can gain the easiest entry to your body and place the biggest burden on its defense system.
No matter the type or size of the building - single family home, office, school, store, hotel, restaurant, hospital, or other
places - creating and maintaining good indoor air quality (IAQ) requires three key strategies: source control,
ventilation and air cleaning. Indoor air is an intriguing, complex environment that contains a myriad of visible and
invisible contaminants. These contaminants generally fall in one of two categories: particulates or gases, vapors and
odors.
Particulates
Particulates are particles that are small enough to suspend in the air. Suspended inorganic particles, such as dust,
pollen, fibers or smoke to name a few examples, are often referred to as aerosols. Suspended organic compounds
and small living organisms, such as bacteria and viruses; mold spores and pieces of a mold colony; dust mites feces
and body fragments; cockroach body parts; and dander from cats, dogs and other mammals, are called bio-aerosols.
Particle size is measured in terms of its aerodynamic properties and is expressed as microns in diameter. Particles
can range in size from very small, which can remain in the air for a long time, up to relatively large, which quickly settle
out of calm air. Table 1 lists common indoor contaminants and their particle sizes.
Inhaling particulates can cause eye, nose and throat irritation and increase the risk for respiratory infections. Health
care professionals are especially concerned about the long-term effects of inhaling fine particles (less than 2.5
microns), because they can travel deep into the lungs where they can remain embedded for years or be absorbed into
the bloodstream. Asbestos and various substances in environmental tobacco smoke (ETS) are well-known examples
and some are recognized carcinogens. Exposure to high levels of fine particles also can play a role in developing
respiratory diseases such as asthma, bronchitis, pneumonia and emphysema. Larger particles (greater than 10
microns) do not cause as much concern, because they get caught in the nose and throat and are cleared from the
respiratory tract by coughing or swallowing.
Gases, Vapors and Odors
The types of gases or vapors most often found in indoor environments include combustion byproducts, such as
carbon monoxide, nitrogen oxides, sulfur dioxide, soot particles and polycyclic aromatic hydrocarbons (PAHs); pet,
human and cooking odors; ETS; volatile organic compounds (VOCs); microbial VOCs; and mycotoxins. Many of these
substances also produce odors, some of which are pleasant while others can be distracting and irritating. Moisture
also is a vapor that must be monitored as too much moisture can support indoor mold growth.
Volatile organic compounds are prevalent in all indoor environments, with as many as 100 to 1,000 different VOCs in
the air where people can easily inhale them. Exposure to VOCs in offices and other business establishments can
cause building occupants to feel uncomfortable, distracted or sick to the point that it interferes with their ability to do
their work or reduces their motivation to work. Reducing the level of VOCs also is very important in homes and
schools, because children breathe in more air with respect to their body mass than adults and thus have greater
exposure to indoor air pollutants. Some types of mold also emit VOCs, known as microbial VOCs or MVOCs, which
are responsible for the characteristic musty, earthy odors associated with mold. People who are sensitive to MVOCs
may experience eye, nose and throat irritation.

A wide variety of molds also can produce mycotoxins at various times during their lifecycles. Building occupants can
experience potentially serious health problems if they are exposed to high levels of these compounds, but this is rare
in most indoor environments.
Although becoming a lesser issue in public buildings, ETS is still found in many homes, hotels, casinos, and in some
restaurants and bars. Environmental tobacco smoke alone contains more than 4,700 airborne substances, including
gases and particles from incompletely burned tobacco, of which 243 are known carcinogens.
Regardless of whether an indoor environment is the product of new construction or renovation, providing good indoor
air quality starts during the design and construction phases and continues throughout a building's life, and, it is never
too late to start managing IAQ in older buildings. Indoor environmental experts recommend three primary strategies
for good IAQ, especially when integrated into a building's overall operation and maintenance. The following highlights
each of these strategies: source control, ventilation and air cleaning.
Source control
The US Environmental Protection Agency (USEPA), the American Lung Association (ALA) and other experts agree
that source control is the only completely effective way to remove pollutants from indoor environments. They also
agree that total eradication of indoor air contaminants often is not feasible or practical. A more realistic goal is to use
building materials, furnishings, finishes, office equipment, and cleaning products and processes that emit low levels of
VOCs. Surface cleaning also removes larger particles and kills bacteria and viruses on floors, furniture, walls,
doorknobs, bedding and linens, and bathroom fixtures. In addition, keeping the heating, ventilating and air-
conditioning (HVAC) system in good working order and air ducts and drip pans clean is important for minimizing dust
and particle accumulation and indoor mold growth within the system.
Source control also involves inspecting a building regularly inside and out for any signs of water damage, which is a
good indicator that moisture levels are high enough to support indoor mold growth. The best way to prevent indoor
mold growth is to eliminate all sources of excess moisture, from leaks in the building envelope, improper building
pressurization, an inefficient or malfunctioning HVAC system, appliances to building occupant activities.
Ventilation
Ventilation and air cleaning are invaluable for picking up where controlling sources of indoor air pollutants leaves off.
The two work hand-in-hand, as many types of air purifiers are an integral part of the HVAC system.
A well-designed and properly operating HVAC system brings in and conditions outdoor air and circulates the air
through the building. The primary benefit beyond warming, cooling and managing the humidity the air is to dilute
indoor air pollutants to minimize their impact on the indoor environment and building occupants. The HVAC system
also transports indoor air contaminants outside. In addition, the HVAC system is invaluable for maintaining
appropriate building pressurization, which is critical for preventing moisture intrusion. The downside is the HVAC
system may bring in outdoor air pollutants as well as pick up indoor pollutants, such as mold spores, allergens, dust
and VOCs from one area of the building and transport them to another.
Air cleaning
Simply stated, with respect to air cleaning the goal is to remove indoor pollutants by trapping them inside a
mechanical device. Experts emphasize that air-cleaning devices alone cannot ensure good IAQ, particularly where
ventilation itself is inadequate. As noted, air cleaning is most effective when used in conjunction with source control
and ventilation (USEPA 2006). Air cleaners / purifiers employ various types of filtration technologies, which can be
used in portable units that can be moved from room to room and can be attached to HVAC systems.

2. AIR CLEANING TECHNOLOGY
When you are trying to repair the air purifiers, make sure you understand the technologies used by the air purifier and
the potential issues that may be inherent in that technology which could effect the efficiency of the air purifier and your
health. Most of air purifiers may use multiple technologies in their design.
Mechanical filtration
Capturing particles in a filter via physical mechanisms without electrostatic
forces characterizes this air cleaning method. These units are capable of
capturing small particulate matter. They utilize a filter media with very high
efficiency ratings. The Letters in the word HEPA stand for High Efficiency
Particulate Arrestance. HEPA filters are composed of a mat of randomly
arranged fibres. Key metrics affecting function are fibre density and diameter,
and filter thickness. The air space between HEPA filter fibres is much greater
than 0.3 microns. A common misperception is that fibrous filters (the most
extensively used in mechanical filtration) work like a sieve, with particles
becoming trapped within the spaces between the fibers. What actually occurs is
that once the particles make contact with the fibers, they remain attached due to
strong molecular forces between the particles and fibers. As a result, the
particles become a part of the filter structure and contribute to a filter's efficiency
by creating resistance of air flowing through the filter. The filter can capture
99.97% of particles as small as 0.3 microns. The disadvantage of HEPA filters is
that the need for a powerful fan leads to increased noise and energy costs
compared to less efficient filtration systems, and replacement filters are
generally quite expensive. Critical design details are important in achieving high
air cleaning performance. If an air purifier using a HEPA filter is not properly
designed, air will bypass the filter as static pressure pushes against the filter and
allow particle escape. Most air purifiers on the market include HEPA filters as a
sales and marketing tactic, but fail to achieve HEPA performance.
Electronic filtration
Electrostatic Precipitators, most commonly referred to as electronic
air purifiers, operate on electrostatic attraction to a collecting section
usually called a electronic cell. A typical two-stage electronic cell has
an ionizer section (the front portion of the cell) and a collector section
(the back portion of the cell). The ionizer wires are maintained at
several thousand volts by the high voltage power supply, which
produces a corona that releases electrons into the air stream. These
electrons attach to the dust particles and give them a net positive
charge. The collector section is composed of alternate parallel plates
which are charged oppositely (positive and ground) and the charged
particulate adheres to the collecting surfaces. The air velocity
between the plates needs to be sufficiently low to allow the dust to fall
and not to be re-entrained in the air stream. The electronic cell is
capable of removing particles in the range 0.01 micron to 10 microns
and can achieve efficiencies around 95 percent. Electronic cell has a
very low pressure drop and high efficiency on very small particulate.
Electronic air purifiers become less efficient as the collecting cell
becomes dirty. As the surface of the collecting area becomes heavily
coated, the charge to attract the particulate is less effective. The
electronic cell must be cleaned regularly to maintain maximum
efficiency. The advantages of electronic air purifiers are they
generally have low energy costs because of low air pressure drop,
the airflow through the units remains constant with use and the
electronic cell is reusable, which avoids long-term filter replacement
costs. Electronic air purifiers also can create ozone as a byproduct of
ionization. However, these devices are not considered to be "ozone
generators" as the level of ozone created is generally low and ozone
production can be reduced by adjusting the high voltage power
supply.

lightning or UV lights .
Unlike electronic cell, the ion generators don't remove the particulate matter, they only cause them to accumulate and
attach themselves to various surfaces around the room. This means that ion generators only have a temporary effect
of eliminating particles from the air. Once the particles lose the charge, they become airborne again. Those charged
particles are more easily trapped in the human respiratory system. Ion generators can produce ozone, either as a by-
product of use or intentionally.
Some air purifiers use negative ion generators, which are installed at the air outlet to fresh the purified air. Negative
ion has proven to be successful in reducing the overproduction of serotonin, and therefore successful in alleviating
depression in some cases.
Electret media filter-synthetic (Hybrid Filters)
Electret media filter is a hybrid of a mechanical filter and electrostatic filter
or an ion generator in an integrated single filter. The media filter made from
synthetic fibers is inherently negatively charged in the manufacturing
process and retains a charge which attracts airborne particles that are
trapped and retained within the fibers in the conventional methods of
impingement. In some cases, ionizers are used to increase the efficiency of
the trapped media. These filters obtain a moderate efficiency on smaller
particles than the electronic cell. Electret media filters must be changed or
cleaned regularly to maintain system efficiency, as the fibers loose their
electrostatic charge as they become soiled.
Negative ion-negative ion generator
Negative ions are negatively-charged electrical particles that are
magnetically attracted to allergens and other airborne contaminates, which
are positively-charged. The newly-formed larger particles are than able to
fall harmlessly to the ground, and out of the air we breathe.

or synthetic filter.
Oxygen

Ozone-ozone generator
Ozone is a molecule with three atoms of oxygen, either
directly or as a by product of ionization and electrical
precipitation. High voltage causes the oxygen molecules in
the air to create ozone (O3). Ozone does not trap particles,
but can remove odors in the air. Manufacturers of air
cleaner systems that produce ozone may refer to the ozone
as "Supercharged Oxygen", "Activated Oxygen" or
"Enhanced Oxygen" Ozone molecules are converted from
oxygen molecules. The ozone molecule (O3) is highly
reactive, so whenever it encounters a floating particulate,
one of the oxygen atoms breaks away to oxidize the
pollutant. This leaves behind O2 (pure oxygen), refreshing
the air even more. Ozone generators do not utilize filters.
These machines operate by introducing the highly reactive
molecule, Ozone (O3) into the air.

This process dissipates air borne pollutants comparably the way that bleaching agents are used to sterilize water.
However, ozone is of concern when considering spaces for human occupancy. The high concentration levels required
for contaminant control are in conflict with potential health effects as established by authorities including the National
Institute of Occupational Safety and Health (NIOSH), and the U.S. Food and Drug Administration (FDA). The problem
is that there is much controversy surrounding the use of these machines as "air cleaners". Ozone is considered a
hazardous workplace chemical by O.S.H.A. (U.S. Occupational Safety and Health Administration), and is also
considered an air pollutant that requires regulation by the E.P.A. (Environmental Protection Agency. Ozone may also
be particularly harmful to people with asthma.

Representative average total oxidant concentrations in some major cities in 1964. Approximately 95 per cent or greater of these
oxidants are generally accepted to be ozone.
0.040 ppm
CSA limit for devices for household use. Measured as sustained concentration in test room.
0.050 ppm
Maximum allowable ozone concentration recommended by ASHRAE in an air conditioned and ventilated space.

level at which nasal and throat irritation will result appears to be about 0.300 ppm.
0.300 ppm
The ozone level at which some sensitive species of plant life began to show signs of ozone effects.
0.500 ppm

exposure could cause lung edema (an abnormal accumulation of serous fluid in connective tissue or serous cavity). Enhances the
susceptibility to respiratory infections.
1.00~2.00 ppm
Los Angeles, California, declares its Smog Alert No. 2 at 1.00 ppm ozone concentration and Smog Alert No. 3 at 1.500 ppm.
When this range of ozone concentration was inhaled by human volunteers for 2 hours, it caused symptoms which could be
tolerated without incapacitation with the symptoms subsiding after a few days. The symptoms were headache, pain in the chest,
and dryness of the respiratory tract.
1.40~5.60 ppm
The pinto bean exposed to 1.4 to 5.0 ppm ozone concentrations for 70 minutes showed some signs of severe injury to mature
leaves.
5.00~25.00 ppm
Experimentation showed that a 3 hour exposure at 12 ppm was lethal for Guinea pigs. Welders who were exposed to 9 ppm
concentration plus other air pollutants developed pulmonary edema. Chest X-rays were normal in 2 to 3 weeks, but 9 months later
they still complained of fatigue and exertional dyspnea (labored respiration).
25.00 ppm and up
Ozone concentrations that are immediately hazardous to human life are unknown but on the basis of animal experimentation, and
exposure at 50 ppm concentration for 60 minutes would probably be fatal.

Activated Carbon Filter
The activated carbon filter can remove gas and odor. This is the physical
process of binding gas molecules to a large surface or pores of an adsorbent
medium. Activated carbon is the most common media used for adsorption
and is produced by heating carbonaceous substances (containing carbon
and derived from organic substances such as bituminous coal, wood or
coconut shell) to form a carbonized char, then activating (oxidizing) with
gases such as steam and carbon dioxide to form pores and creating a highly
porous adsorbent material. The effectiveness of odor removing media is
related to the amount and type of gasses present in the air, the quantity, type
and depth of the adsorbent material and the velocity of the air traveling
through the media.
The location of the odor adsorbing media relative to the particle filtration
media is also important. If the odor adsorbing media is placed first, then
particles in the air will cover the porous structure of the odor adsorbing
media and reduce its effectiveness at trapping odors. By placing the HEPA
or electronic cell first, particles in the air are captured before the air reaches
the odor adsorbing media and allows the porous structure of the odor
adsorbing media to have maximum effectiveness at capturing gasses. Room
conditions such as air temperature and humidity also effect the capacity of
adsorbents to remove odors.

Ultraviolet (UV) Light
UV light is not visible to the human eye. It refers to the part of the wavelength spectrum below visible violet light and
above x-rays and gamma rays. All light is a form of electromagnetic radiation. The distinguishing aspect of UV light is
the wavelength which is longer than x-rays but shorter than visible light. It is named because the spectrum consists of
refrangible electromagnetic waves with frequencies higher than those that humans identify as the color violet. UV light
is typically found as part of the radiation received by the Earth from the Sun. Most humans are aware of the effects of
UV through the painful condition of sunburn. The UV spectrum has many other effects, including both beneficial and
damaging changes to human health. This technology is commonly used in a variety of healthcare and water quality
applications where the control of microorganisms is desired.
UV light possesses just the right amount of energy to break organic molecular bonds. As micro-organisms pass by the
UV rays radiated from the ultraviolet lamp, this bond breakage translates into cellular or genetic damage for
microorganisms, such as germs, viruses, bacteria, fungi (like molds), etc. This results in the destruction of the
microorganisms. Many of the air purifiers use UV lamps to kill microorganisms and activate the photo catalyst filter
around it.

Fig. 1.2-9 How photo catalyst works.
Fig. 1.2-8 UV lamp and photo catalyst of 200T.
Photo catalyst
A photo catalyst is a chemical compound that becomes highly reactive when exposed to various wavelengths of UV light.
Photo catalytic oxidation is achieved when UV light rays is combined with a TiO2coated filter. TiO2refers to Titanium
Oxide. This process creates hydroxyl radicals and super-oxide ions, which are highly reactive electrons. These highly
reactive electrons aggressively combine with other elements in the air, such as bacteria and VOCs. Once they are
bounded together, the chemical reaction takes place between the super-charged ion and the pollutant, effectively
"oxidizing" (or burning) the pollutant. This breaks the pollutant down into harmless carbon dioxide and water molecules,
making the air more purified.
Photo catalytic oxidation
The key to PCO is the photo catalyst. Titanium dioxide (TiO2) is a
semiconductor photo catalyst with the band gap energy of 3.2eV.
When this material is irradiated with photons of less than 385 nm, the
band gap energy is exceeded and an electron is promoted from the
valence band to the conduction band. The resultant electron-hole pair
has a lifetime in the space-charge region that enables its participation
in chemical reactions. The most widely postulated reactions are shown
as Fig. 1.2-10 below.
Hydroxyl radicals and super-oxide ions are highly reactive species that
will oxidize volatile organic compounds (VOCs) adsorbed on the
catalyst surface. They will also kill and decompose adsorbed bio-
aerosols. The process is referred to as heterogeneous photo catalysis
or, more specifically, photo catalytic oxidation (PCO). Several
attributes of PCO make it a strong candidate for indoor air quality
(IAQ) applications. Pollutants, particularly VOCs, are preferentially
adsorbed on the surface and oxidized to (primarily) carbon dioxide
(CO2). Thus, rather than simply changing the phase and concentrating
the contaminant, the absolute toxicity of the treated air stream is
reduced, allowing the photo catalytic reactor to operate as a self-
cleaning filter relative to organic material on the catalyst surface.
Photocatalyst
UV lamp
VOC is an acronym for Volatile
Organic Compounds. VOCs are
organic chemicals that contain the
carbon element. They are carbon
compounds that easily evaporate at
room temperature and often have a
sharp smell. They can come from
many products, such as office
equipment, adhesives, carpeting,
upholstery, paints, solvents and
cleaning products. Some VOCs can
cause cancer in certain situations,
especially when they are
concentrated indoors. VOCs also
create ozone, a harmful outdoor air
pollutant.

FEATURES AND SPECIFICATIONS
The air purifier functions as an air cleaner by helping to disinfect
airborne microorganisms and removing particulates from the air.
The centrifugal fans of the unit draw air through the front panel on
the front of the unit. Then it passes through the Pre-filter, the
Electronic cell, the Activated carbon filter and the UV-Photo
catalytic sterilization chamber. The purified air is then released
through the outlet on the top of the unit.
The Air is Cleansed in Six Stages:
1. The Pre-filter traps large dust particles.
2. The two-stage electrostatic precipitator (Electronic cell) captures
airborne particles, as small as 0.01 microns. In the ionizing section
of the electronic cell, billions of microscopic particles become
electrically charged as they pass through the powerful electric field.
The collector plates immediately attract and collect these charged
dust and dirt particles.
3. The activated carbon filter absorbs and reduces odors,
chemicals and gases, removes tobacco smoke, the smell of food
and other odors.
4. The UV sterilization chamber kills bacteria and viral
microorganisms such as influenza, TB and Legionnaire's Disease
as well as other harmful contaminants.
5. When UV light hits the photo catalytic filter; it creates e- and h+,
which have an excellent effect in the decomposition of odors.
6. The unit also generates negative ions that freshens the room air.

2.1 PRE FILTER
The pre filter is an important part of the unit. Large particles (lint,
hair) are caught by the pre filter so to protect the electronic cell.
Cleaning the Pre filter Regularly
To ensure optimum performance from the air purifier, the pre filter
and cell must be cleaned regularly-every one to three months.
Washing frequency will vary depending on the number of family
members, pets, activities (such as cooking or woodworking) and
smoking habits. Use the wash reminder schedule mounted on the
back of the unit to help establish and maintain a regular cleaning
schedule (use marker pen).
-Stop the operation and unplug the power plug from the electrical
outlet.
-Hold the front panel (Air intake) upper portion (Left and right side)
and pull the front panel toward you (Fig. 2.1-1).
-Remove the pre filter by pulling out in front while holding the front panel.
-After using a vacuum cleaner to remove any dust, clean with water.
If it is very dirty, use a soft brush or a neutral cleaner to clean then
dry well in the shade. Do not wash the pre filter in the dishwasher or
car wash.
Pre filter Ground Plate
The pre filter of the unit is manufactured
with metal frame and metal mesh.
When the unit is working some charges
from the ionizing section of the
electronic cell will accumulate on the
metal mesh of the pre filter. If the metal
mesh pre filter does not contact with
ground plate it will discharge itself to
the air and you can hear cracking
sound.
The purpose of pre filter ground plate is
to connect it to the ground to avoid
sparking or discharge of the pre filter.
Do not defeat the pre filter ground plate.

1. To reduce risk of electric shock always stop the operation and unplug before maintenance.
2. The pre filter should be inspected frequently and collected dirt should be removed from it
regularly to prevent excessive accumulation that may result in flashover or a risk of fire!
3. The unit is not designed to be explosion proof and therefore should not be used in
atmosphere containing explosive dust or gases. Do not operate without filters in place.
4. Do not cleanse the unit or parts with chemicals such as alcohol, gasoline, paint thinner,
etc.. It may cause fire or lead to breakdown of the system.

2.2 ELECTRONIC CELL
The unit employs a two-stage electronic cell for particulates
collection. It has a stage of ionizer wires and a stage of collector
plates. The ionizer wires are maintained at several thousand
volts, which produce a corona that releases electrons into the air
stream. As the dirty air passes through the intense high voltage
electric field surrounded the ionizer wires, all particles, even the
smallest are given an electric charge. The air passes into the
collector stage where the alternate parallel plates have positive
and negative charges, creating a uniform electrostatic field. Since
opposites attract, the charged particles stick to the collector
plates, having an opposite electric charge. Consequently, the air
leaving the air purifier contains very few particles. Theses
electrons attach to dust particles and give them a net negative
charge. See Fig. 2.2-2.
How Does the Electronic Cell Work?
The high voltage power supply provides the cell high voltage to
the ionizer section and low voltage to the collector section
through the two power contact terminals. If the power supply is
broken the cell cannot work, failing to collect the particulates in
the air.
Fig. 2.2-2 How does the electronic cell work.
The cell needs high voltage to the ionizing wires and low
voltage to the positive plates of the collector section.

Fig. 2.2-1 Remove the electronic cell.
Stop the operation and unplug the power
plug from the electrical outlet. Open the front
panel and take out the cell.
The first stage, the ionizer section of the cell is the
charging section composed of ionizing wires and
grounded plates. When the power supply provide
high voltage to ionizing wires it create a strong
electrical field and give charges to the particles in
the air stream. Some of the charged particles are
attracted to the ground plates.
The second stage, the collector
section of the cell is the collecting
section composed of alternate
parallel plates which are positive
plates and ground plates. When the
positively charged particles are
passing through the collecting
section they will be trapped by the
ground plates.

Fig. 2.2-4 Cleaning the cell.
After cleaning, make sure to dry the cell
thoroughly before reinstalling. If the cell is wet,
it can cause the check unit indicator light
flashing or breakdown of the cell and unit.
Ozone generation of the cell
Electronic cell generates a small amount of ozone, about 0.005 to 0.010
parts per million (ppm). The amount is highest when the cell is new. The
average person can detect the odor of ozone in concentrations as low as
0.003 to 0.010 ppm. The U.S. Food and Drug Administration and Health and
Welfare Canada recommend that indoor ozone concentration should not
exceed 0.050 ppm. As a comparison, the outdoor ozone level in major cities
is sometimes higher than 0.100 ppm. If desired, the ozone generated by the
air purifier can be reduced by cleaning the cell, replacing the carbon filter or
adjusting the high voltage power supply to produce a lower high voltage
output. However, the adjustment of the power supply will reduce ozone
production but will also reduce air cleaning efficiency. See Fig. 2.2-5.
Discoloration of the cell
Occasionally, after the cleaning process, the cell may seem stained. If the
stain is black or very dark, it is probably detergent residue and should be
rinsed off at once. If yellowing appears, it is probably stain from tobacco or
other smoke. The yellowing does not affect air cleaning efficiency. Use
ammonia based or butyl based detergent to clean tobacco tar and other
smoke residue from the collector plates.
Cleaning the electronic cell
In order to keep the air purifier operating at peak efficiency, it is important to wash the electronic cell regularly.
Washing frequency will vary depending on the air quality where the unit operates. If the air is of very poor quality, the
efficiency of the cell will degrade rapidly, and may necessitate weekly cleaning. Under normal operating conditions, the
cell should be cleaned every one to three months. When you hear frequent sparking sound from the cell you will need
to clean the cell immediately. Use the wash reminder schedule mounted on the repair cover of the unit to help
establish and maintain a regular cleaning schedule.
The electronic cell can either be submerged in a bathtub or other suitable container and rinsed, or it can be washed in
an automatic dishwasher.
Voltage output

Fig. 2.2-5 Adjust the high voltage
output by rotating the adjustor with

1. When cleaning the cell, wear rubber gloves to avoid detergent contact with skin.
2. When cleaning be careful not to cut your hands on the ionizing wire. (Wearing rubber gloves is safer.)
3. Be careful not to snag or cut the ionizing wire. If the ionizing wire is cut, replace it immediately. If the unit
is operated with the ionizing wire cut, there will be no dust collection.
3. Slide in the cell so the airflow arrow points toward the machine.
4. After cleaning, make sure to dry the cell thoroughly before reinstalling.

Fig. 2.3-1 Stop the operation and unplug
the cord from the electrical outlet. Open
the front panel, simply pull out the
activated carbon filter.
2.3 ACTIVATED CARBON FILTER
Activated carbon, the universal adsorbent, has a capacity for virtually all
vapor contaminants and will adsorb and retain a wide variety of chemicals
at the same time.
The adsorb diffuses thru the surface film to the macropore structure. Then,
due to van der Walls' forces, the gas molecule migrates into the micropore
structure, condensing during this movement, and finally stopping when
either the forces become balanced or it becomes physically blocked.
This molecule, which was an objectionable gas, will remain a liquid inside
the carbon until it receives enough energy, in the form of heat, to excite it. If
this condition arises, the molecule will begin moving toward the surface. If
enough energy (heat) is absorbed, it will be vaporized, returned to a gas
and be released back into the air stream, i.e. the process will be reversed.
For information, see page 1-6 in this manual. The activated carbon filter of
the unit is located behind the electronic cell (Fig. 2.3-1). To improve the
odor removing performance, the unit utilizes a carbon powder impregnated
pad not granular form. Room conditions such as air temperature and
humidity also effect the capacity of adsorbents to remove odors.
The activated carbon filter should be replaced when it is no longer effective
in eliminating odors.
2.4 UV lamp and photo catalyst
After removing the activated carbon filter, you can see two lamps
and photo catalyst behind them. The unit utilizes nano technology
photo catalyst and 6 watt UVC lamps in the 254 nm range.
UVC utilizes the short wavelength of UV that is harmful to forms
of life at the micro-organic level. It is effective in destroying the
nucleic acids in these organisms so that their DNA is disrupted by
the UV radiation.
When the photo catalyst (TiO2) captures UV light, it forms
activated oxygen from oxygen in the air. This process is similar to
photosynthesis, in which chlorophyll captures sunlight to turn
water and carbon dioxide into oxygen and glucose. The formed
activated oxygen is strong enough to oxidize and decompose
organic materials or smelling gas, and kill bacteria. For more
information, see PART I GENERAL DESCRIPTION ON AIR
CLEANING.
Replacing the UV lamp
When the UV Lamps indicator light flashes, it is time to replace
the UVC germicidal lamps. After removing the UV light blocker,
gently rotate the lamp a quarter turn in either direction until it
unlocks from the socket. Pull the pins out the sides of the socket,
one end at a time. After replacing the UV lamps, press the
RESET2 button on the remote control for 12 times (New model is
changed to 5 times) to reset the UV lamps life. You also can
press and hold the reset button on the main circuit board for 6
seconds to initiate the UV lamp life.
The photo catalyst will not be replaced. However, remove any
dust by a vacuum cleaner.
Replacing the activated carbon filter
The unit has a Filter Life indicator on the display panel, the Filter Life LED indicator light will blink to indicate it is time
to replace the carbon filter. The time between activation of the Filter Life indicator light is based on the unit run time
that is selected by the manufacturer. In fact, the life of the carbon filter will depend on the concentration of odors and
fumes in the air passing through the air purifier.
After replacing the activated carbon filter, press the RESET1 button for 12 times (new model is changed to 5 times) on
the remote control or until you hear the beep sound from the unit to initiate the Filter Life indicator light. You also can
press the reset button on the main circuit board to reset the activated carbon filter life. For more information about the
remote control reset.
Fig. 2.4-1 Remove the front panel and the swing
nut on the UV light blocker to remove the UVC
lamp.
Always unplug the unit before cleaning,
servicing or replacing the UV lamp.
Never look directly at UV lamp. Direct
exposure to germicidal light can cause
temporary or chronic damage to your
eyesight, or even blindness.

2.5 NEGATIVE ION GENERATOR
Studies about negative ions have shown that some people
become moody, tired, depressed, or experience difficulty
concentrating when negative ion counts are low, or when
positive ion counts are high, such as in front of a computer
monitor. Negative ions help eliminate pollen, mold spores,
dust, pet dander, and many other allergy causing
particulates from the air we breathe.
The negative ion generator of the unit is secured to the fan
housing by a screw and the brush terminal is on the air
outlet. See Fig. 2.5-1. The negative ion has two wires, one is
red, another is black. Make sure to connect the wires
correctly.
Control the negative ion discharge by remote control
When the Neg. Ion indicator light is on, negative ions are
discharged. The negative ion generation is controlled by
remote control. One press of the Neg. Ion on the remote
control will stop the generation of ions and the indicator light
will go out. See Fig. 2.5-2~3 below.
Fig. 2.5-2 When the Neg. Ion
is on, the negative ion
generator is working.
