Chapter 1 – Improving Indoor Air Quality
Chapter 1 – Air Cleaning Systems and Indoor Air Quality
1.1 Improving Indoor Air Quality
Air cleaning can play an important role when it comes to improving indoor air quality. However, it should be noted
that air cleaning should be used in conjunction with pollution source control and ventilation, wherever possible.
Strategy to improve indoor air quality
To tackle any indoor air quality problem, keep the following three-step strategy in mind:
1. Eliminate or reduce the air pollution source as much as possible.Source control is by far the most effective way to
improve indoor air quality, since it sets out to deal with air pollution at the point of origin.
2. Ensure that sufficient fresh air is entering the room from outside. Air cleaners are not a substitution for sufficient
ventilation. They are not able to reverse the conversion of oxygen (O2) into carbon dioxide (CO2), caused by
breathing and combustion processes.
3. Ensure the QAir system can clean enough air to cope with your room size.The actual hourly air volume cleaned
by the system should be at least double the air volume of your room. f the rate at which pollutants enter the room
air is high or the indoor air quality requirements are stringent, the hourly air delivery of the system needs to
exceed the room air volume several times.To achieve that level of air turnover,it may be necessary to employ more
than one system.
Air Cleaning Results
Although air cleaners may be advertised and sold to be suitable for use in specific indoor environments and to deal
with specific indoor air quality problems, the manufacturer and distributors make no claim as to the specific air
cleaning results that are achieved under the user’s individual operating conditions.The air quality improvements that
can be realized with the QAir® system (as with any air cleaner) in indoor environments depends to a significant
degree on circumstantial factors, which are out of the control of the manufacturer or distributors. mportant factors
which will influence the air quality improvements that can be achieved in an indoor environment with an air cleaner
include:
•Type of air pollutants present
•ntensity of the pollutant source(s)
•Pollutant concentration
•Size of the indoor environment (room size)
•Operating speed of the unit
•Number of air cleaners placed in the indoor environment
•Saturation state of the filters in the air cleaner
Consult a qualified specialist to determine an effective and comprehensive indoor air quality strategy.

2.3 Choosing a Suitable ocation
When choosing a suitable location for the
QAir system, keep the following
considerations in mind:
•Choosing the most suitable room for the
system will depend on where you would
like the focus of the air cleaning efforts.Two
main considerations are the time you spend
in a particular room and the location of the
main air pollution sources.As a general rule,
the closer the system is located to the air
pollution source, the better the air cleaning
performance in the room. Although an air
cleaning result may be achieved in adjacent
rooms, the main air cleaning will take place
in the room where the system is located.For
the best air cleaning results in adjacent
rooms,make sure that doors to these rooms
are left wide open.
•For best performance, the system should be positioned at least 30 cm (1 foot) away from the nearest vertical
surface, such as a wall or a cupboard. n general, the more centrally the system is positioned, the better the
performance.
•Position the system close to a power outlet and make sure that the power cable is positioned in a way that it does
not present an obstacle that could be tripped over.
•Make sure that the system is positioned in such a way that the control panel is easily accessible.
2.4 Connecting to Power
1. Plug the connector end of the power cord into the recessed power inlet socket on the back of the system.
2. Plug the other end of the power cord into a power outlet or power strip.
Important: The only way to disconnect power completely is to unplug the power cord.
Do not use the IQAir® system when the power cord becomes damaged.The power cord may be replaced with an
approved cord with a two-pole plug.These power cords are commonly used for computers and similar appliances.

1.Room air is drawn into the system via two arched open-
ings at the base.
2. The air is drawn in through the HEPA pre-filter that al-
ready removes most pollution particles.
3. At the heart of the system, sandwiched between the
filters, is a powerful centrifugal fan which generates the
airflow.
4. The air is pushed through four cartridges that contain
up to 7,8 kg of gas phase control media, which retains
specific chemical pollutants.
5. Particulate post-filter sleeves hold back abrasion
particles from the gas phase filter media.
6.Low turbulence,low velocity air is returned to the room
via the EvenFlow™ diffuser.

Menu Key
The Menu key allows access to any one of eleven menus.Pressing the Menu key once allows access to the first
menu function. Pressing the Menu key twice allows access to the second menu function, and so on. f no key is
pressed for 15 seconds in a menu window, the display will revert to the main display window. Tip: f you are in a
menu window and would like to remain in the window for more than 15 seconds, keep the key depressed.
Enter Key
The Enter key, if pressed for 3 seconds, allows the modification of a setting. The enter mode is indicated by a
flashing cursor on the modifiable setting. Pressing the Enter key again will save any entry and move the cursor to
the next modifiable item in the display window.When the last modifiable choice in a window is confirmed with the
Enter key, the enter mode is automatically terminated and the new settings are saved.
Filter ife EDs: Whenever the system is on, the colour of the filter life LEDs (light emitting diodes) indicates the
state of the individual filters in the system. Note: The positions of the filter life LEDs on the control panel correspond
to the actual positions of the filters within the system.
The filter life indicator LEDs signal four possible stages in the life of the filter:
1. Green: The filter is still within 80% of its estimated life span.
2. Orange: The filter is approaching the last 20% of its estimated life span.
3. Red: The filter has reached the end of its estimated life span.
4. Red blinking: The filter has passed its estimated life span and should be replaced immediately.The QAir system’s
effectiveness is likely to have been reduced dramatically, either due to a reduction in airflow
(particle filters are clogged) or a reduction in filter efficiency (gas phase filter is saturated).
Fan Speed EDs: These LEDs simulate the fan speed through the frequency of their rotation.The faster the rotation
of the fan speed LEDs, the faster the actual fan speed of the unit.
4.2 Control Panel ocking Function
The control panel can be locked to avoid tampering with the settings.To
lock or unlock the control panel keys, the Menu and the Enter key have
to be pressed down simultaneously for 3 seconds.The activated locking
function is indicated with a star symbol in the control panel display.The
locking function is cancelled by disrupting the power supply.
4.3 Fan Speed and Air Delivery
The QAir system can be set to run at six different fan speeds which correspond to six different airflow rates. Speed
1 is the lower, speed 6 the highest fan speed. The higher the fan speed, the more room air will be filtered by the
system. The high fan speed settings provide additional air cleaning power to deal with situations of elevated
pollution levels.
To allow better evaluation of the system’s performance at different fan speeds, the standard display window shows
not only the fan speed, but also the air delivery rate (airflow). The displayed airflow is factory preset and is not
measured by the system itself.
4.3.1 Regulating Fan Speed
1. When the QAir system is switched off (standby mode),the first line of the LCD
display shows the model name. To switched the system on, press the Power
key on the far left of the control panel.
2. The LCD now displays the fan speed and the corresponding airflow rate.Note:
The system starts at the fan speed at which it was running when it was last
used.
3. To change the fan speed, press the key.

4.3.2 Air Exchange Rates in Differently Sized Rooms
Any air cleaner can only be effective if it filters a sufficient amount of air in an indoor environment. For general air
cleaning purposes, the QAir system should be able to filter the room air volume at least twice every hour on the set
fan speed to achieve a significant air quality improvement. f the intensity of the pollution source is high or a high
degree of purification is needed, more air changes may become necessary. n order to achieve the desired number
of air changes, more than one air cleaner may be required.
The number of air changes that are necessary to attain a certain level of indoor air quality will depend on a variety
of factors, including:
•intensity of air pollution source: The higher the rate at which air pollutants are produced or enter the indoor
environment, the higher the air cleaning rate in the room needs to be.
•filtration efficiency for specific air pollutants: The lower the filtration efficiency for certain pollutants, the more
air changes are required to reduce these pollutants.
•desired improvement in air quality: The higher the desired improvement in air quality, the more air changes are
required.
The number of ACH produced by an QAir system in a specific environment are calculated as follows:
hourly air delivery of the QAir system (m3/h)
= air changes per hour (ACH)
air volume of the room (m3)
N.B.The air delivery rates at the various fan speeds settings are listed on the “Technical Specifications”sheet.
Example calculation: A room with the dimensions of 4x 4 x 2.6 meters has an air volume of 41.6m3.With an air
delivery rate of 240 m3/h,the room air volume will be circulated over 5.7 times per hour by the
QAir® system (240 m3/h ÷ 41.6 m3= 5.77 ACH).
4.4 Using the Menu Functions
The QAir control panel offers a choice of several menu options which allow access to the advanced features of the
system. n total there are ten active menu functions.The functions can be accessed in standby or running mode.
4.4.1 Menu Overview

Chapter 4 – sing the Control Panel

4.4.2 Filter ife Monitor
The QAir system is equipped with an electronic Filter Life Monitor that calculates the remaining life of the system’s
filters.Thanks to the Filter Life Monitor, the user does not have to guess when filters need to be replaced or replace
them at fixed intervals (which rarely correspond to the actual amount of use). The Filter Life Monitor watches over
the most important factors affecting the life of the individual filters. The Filter Life Monitor display shows the
remaining life of each individual filter at any given time.
1. To reach the Filter Life Monitor display from the main display window,
press the Menu key once.The remaining life of the filter 1 will appear.
2. Press the key to view the remaining life of the other filters in the system.
3. The remaining life of the filters is expressed in hours of operation at the
current speed setting and the programmed filter load indices.
How the Filter ife Monitor Works
The basis for the calculation of the remaining filter life is the already elapsed operation time at the set fan speeds and
filter load indices during that period. This input is compared with an internal memory bank which contains infor-
mation about the different filters’ lives under specific conditions of use.
The Filter Life Monitor makes a calculation of the remaining filter life, taking into account not only past use of the
system, but also likely future use. As reference for future use, the filter life monitor uses the fan speed and the filter
load indices which are programmed at the time.
The relationship between the current fan speed, the current filter load indices and the remaining filter life displayed
can be expressed as follows:
•The higher the current fan speed setting, the shorter the displayed remaining filter life.
•The higher the current filter load index setting, the shorter the remaining filter life displayed for the affected filter.
7. Filter ife Reset
Allows the resetting of the filter life counter after replacing a filter
element.
8. Airflow Units
Allows to switch the airflow units between cfm (cubic feet per minute)
and m3/h (cubic meters per hour).
9. anguage
Allows the modification of the display language.
10. Filter oad Index Setting
Allows the modification of the air pollution index, so the system can
calculate the remaining filter life, taking pollution intensity into account.

4.4.9 Changing the Airflow Units
N.B.The air delivery (airflow units) displayed in this manual are examples only
and will vary according to model.
1. You can change the air volume units which are displayed from imperial to
metric,i.e. from cubic feet per minute (cfm) to cubic meters per hour (m3/h),
and vice versa,by pressing the Enter key for three seconds either when the
unit is switched on or in standby mode.
2. When the first character of the air volume units starts to flash, press the 
key once to change the units.
3. Press the Enter key to confirm the air volume unit change. Until modified
again, the airflow rate will now be displayed in the newly selected units.
The Filter Life Reset function allows the filter life counter to be reset after a new filter has been inserted. As a result,

4.4.11 Filter oad Index Setting
The filter load indices are used by the filter life monitor for a more accurate calculation of the remaining filter life.The
filter load indices are based on air pollutant groups that have particular impact on the life of the QAir system’s filters.
Each index can be adjusted to reflect the pollution levels in a certain indoor environment.
The Filter Load ndex Menu allows to view and modify the filter load indices for:
•Large Dust
•Chemicals
•Fine Dust
arge Dust Index: This index is based on the group of coarse or heavy dust. This dust can contain particles with
several millimeters in length down to particles a mere 0.003 mm in size.This type of dust will generally settle within
an hour after generation or agitation on top of surfaces. t consists of fibers, pollen, spores, dander, wood dust, etc.
Chemical Index: This index is based on the group of gaseous organic compounds.These are organic chemicals that
are present in the air in the form of gas molecules. This group includes solvents, hydrocarbons, such as benzene,
formaldehyde, perchlorethylene, styrene, toluene and xylene.
Fine Dust Index: This index is based on the group of fine dust particles.This type of dust is smaller than 0.003 mm
(3 µm) in size and will remain airborne for long periods of time. This dust group is made up of small combustion
particles that are created as the result of combustion processes of automobiles, small allergen particles such as cat
allergens, tobacco smoke particles, etc.
4.4.11.1 Determining the Filter oad Index
The setting for each of the filter load indices can range from“very low” to“very high”.The system is supplied with the
following default settings:
•Large Dust ndex: average
•Chemical ndex: average
•Fine Dust ndex: average
There are a number of factors that may make a modification of the default settings necessary in order to ensure the
most accurate filter life display possible.
Tobacco Smoke
The amount of tobacco smoke in the room air can have a significant effect on filter life. f tobacco smoke exposure is
regular, the filter load indices for each pollutant group should be adjusted to “high”or “very high”.
Presence of Gases and Chemicals
Gases and chemicals may be set free from solvents, paints, varnishes and from vehicle or industrial emissions, as well
as pesticides. Such pollutants influence the life of the gas and odour filter in the QAir® system. f there is a regular
presence of gases and chemicals, it is recommended to increase the Chemical ndex to “high”or “very high”.
Dusty Environments
Environments with a high dust levels are likely to shorten the lives of the pre-filter and the HEPA-filter. f there is a
frequent high dust content in your environment, set the Large Dust ndex to “high” or “very high” (Tobacco smoke
exposure should not be used for the definition of a“dusty environment”).

4.4.11.2 Modifying the Filter oad Index
The Filter Load ndex menu allows the adjustment of the individual pollution
indices (large dust,chemical and fine dust) to reflect the actual pollution levels in
a particular environment more closely. This enables the Filter Life Monitor to
perform a more precise calculation of the remaining filter life.
1. Press the Menu key nine times to reach the Filter Load index menu.
2. Press and hold the Enter key until the cursor appears.
3. Press the key to modify the Large Dust index to reflect the large dust
pollution levels found in the environment where the system is used (for
guidance, see previous section).
4. Press the Enter key to save the Large Dust index setting.
5. Press the key to proceed to the Chemical index.
6. Press and hold the Enter key until the cursor appears.
7. Press the key to modify the Chemical index to reflect the chemical
pollution levels found in the environment where the system is used (for
guidance, see previous section).
8. Press the Enter key to save the Chemical index setting.
9. Press the key to preceed to the Fine Dust index.
10. Press and hold the Enter key until the cursor appears.
11. Press the key to modify the Fine Dust index to reflect the fine dust
pollution levels found in the environment where the system is used (for
guidance, see previous section).
12. Press the Enter key to save the Fine Dust index setting.

imitations of Filter oad Indices
The concept of filter load indices allows for a more precise calculation of the remaining filter life than with regular
filter life counters.Yet, the determination of filter load indices underlies in its definition some natural limitations. For
this reason it may become necessary to change filters before the expiry of the indicated filter life, especially if there
is a noticeable decrease in filtration performance. n such a case, it may be necessary to adjust the appropriate filter
load settings to a higher value.
