ABOUT ALEN®AIR PURIFICATION
Only Alen offers multi filtration technology; HEPA, Ionizer, UV, and Photo-
Catalytic Oxidation providing the best solution for you and the environment
at the best price. We are the first and only air purifier manufacturer to offer a
lifetime warranty. We’re that confident in our quality and want none of our
air purifiers to ever end up in a landfill. Our commitment to our environment
goes beyond our lifetime warranty, all of our air purifiers are ozone safe.
TRUE HEPA FILTRATION
High Efficiency Particulate Air (HEPA) filters can remove 99.97% of particles
0.3 microns and larger (keep in mind 99% of the airborne particles are less
than 1 micron in size — a human hair is 60 microns in diameter). HEPA filters
eliminate mold spores as well as bacteria and of course larger items such as
dust, pet dander and pollen from the air. Alen’s HEPA filtration has tested at
over 1,000% better than a leading ionic air purifier and up to 50% better than
leading HEPA type air purifiers by the world’s leading independent test lab.
This is the same technology as recommended by the US Department of
Homeland Security to remove harmful airborne particles in a terrorist threat.
UV LIGHT (ULTRAVIOLET)
UV-C light sterilizes airborne viruses, bacteria and other microorganisms.
Certain wavelengths of UV-C light damage the DNA or RNA of viruses, bac-
teria, and other pathogens. Since DNA and RNA carry genetic information
necessary for reproduction, the UV-treated microorganisms lose the ability to
multiply and cause disease. It is recommended to use the UV light when-
ever the unit is turned on to maximize the benefits of the air purifier.
To turn on the UV light, when the unit is already turned on, simply touch the
UV button.
IONIZER
Negative ions, specifically negatively charged oxygen molecules (differ-
ent than ozone), have been shown in university and laboratory tests to
have beneficial effects on human health. Similarly, it has been proven that
healthy environments have higher levels of negative ions, so in our commit-
ment to superior indoor air quality all of our purifiers have negative ionizers.
Used alone, negative ionizers are not effective in removing particles from the
air. A HEPA air purifier with ionization like any of our air purifiers has a nega-
tive ionizer rod that produces a small number of negative ions. It is important
to ensure that an air purifier with an ionizer does not contribute unsafe levels
of ozone as the side effects can be worse than the benefits. Alen air purifiers
are ozone safe. It is recommended to have the ionizer on whenever the unit
is turned on in order to maximize the benefits of the air purifier.
PHOTO-CATALYTIC OXIDATION (PCO)
The A375 UV is best in class and only air purifier available that permanently
removes a wide range of gases, volatile organic compounds, smoke, and
ammonia. Other gas air purifiers typically use carbon, which can be a prob-
lem because carbon stores gases which can be released at a later whereas
our solution permanently eliminates the gas/odor on contact. Exclusive
targeted technology was developed to address specific indoor air pollutants
by PhD chemists and patented.

USING AN A375UV AIR PURIFIER
The A375UV is designed for optimal performance in rooms up to 800 square
feet; in this size room the air will be circulated through the air purifier up to
four times an hour. When using the air purifier for the first time in a room,
many prefer to use a higher fan speed like speed three or four, for a couple
of hours in order to clean the room’s air initially. For normal, daily use it is
recommended to use the air purifier on speed one or two.

KNOW YOUR AIR PURIFIER
Control Panel
1. On/Off Button – Press the On/Off button to turn the air purifier on, press
again to turn the air purifier off. The air purifier will run continuously unless
it is turned off manually or the Timer function is utilized.
2. Filter Replacement Indicator – The Clean Indicator light will come on af-
ter 4,000 hours of operation (about 6 months if the unit is run continuous-
ly). When the filter is replaced, you can reset the Clean Indicator light by
pressing the Timer button for 5-10 seconds while the unit is running.
3. Fan Speed – The Speed button is used to adjust the fan speed of the air
purifier. The fan speed options are 1, 2, 3, 4, 1auto. Each time the Speed
button is pressed, the fan speed will increase. Once the highest fan
speed is reached, the cycle will repeat.
4. UV Button – The UV button turns the UV lamp(s) on and off. Press the UV
button to turn the UV lamp(s) on, press again to turn off. The UV lamps
are used to kill bacteria and virus particles in the air. The UV lamps also
interact with a photocatalyst filter inside the air purifier to decompose
odors in the air such as formaldehyde, alcohol, and ammonia.
5. Ionizer – Turn the Ionizer on by pressing the Ion button while the air puri-
fier is running, press again to turn the Ionizer off. The Ionizer is used to
assist with the removal of dust, pollen, pet dander, and mold spores by
releasing negative ions into the air. The negative ions attract particles
and make them “stick” together. The particles are then larger and more
easily caught by the HEPA filter.
6. Timer – The Timer should be used when you want the unit to turn off au-
tomatically. While the air purifier is turned on, press the Timer button to
set the desired run time (hours). The air purifier will automatically turn off
once the timer has counted down to zero. The Timer button is also used
to reset the “Clean Indicator” light.
LCD Display
1. Fan Speed – Displays the current fan speed.
2. Odor Sensor – Displays the current level of odor being sensed. The lowest
level is shown by a single dash. As the level increases the dash will get
larger from right to left.
3. Dust Sensor – Displays the current level of dust being sensed. The lowest
level is shown by a single dash. As the level increases the dash will get
larger from left to right.
4. Timer – Displays the amount of time remaining on the timer, before the
unit will shut off.

HOW TO USE THE REMOTE CONTROL REPLACING THE UV LIGHT
1. With the front of the unit facing up, pull up the lower end of the inlet grill
and push it toward the display panel at the top of the unit, then remove
it.
2. Remove the HEPA filter by lifting the pull string.
3. Unscrew the screws on the lampshade with a screwdriver, then remove
the lampshade.
4. Gently rotate the bulb a quarter turn in either direction until it unlocks
from the socket. Pull the pins out of the sides of the socket, one end at a
time.
5. Unpack the new UV bulb gently by handling the ends only. Starting with
one end of the bulb, then the other, gently insert the metal pins on the
bulb into the white slotted socket one pin at a time. Once the ends of
the buld are completely inserted into the socket, rotate the bulb a quar-
ter turn until it locks into place.
6. Reinstall the lampshade.
7. First install the bottom of the filter into the air cleaner, then the top.
8. Hook the fasteners on the intake grid into the holes on the air cleaner
first, then push down on the two sides of the inlet grid until the cover
snaps into place.
IMPORTANT: Your remote control requires 2 (AAA) batteries for operation.
Do not mix old and new batteries. Do not mix alkaline, standard (carbon-
zinc) or rechargeable (nickel-cadmium) batteries.

REPLACING THE FILTER
The filters used in all of Alen air purifiers are HEPA filters and are not designed
to be washed, cleaned or otherwise reused. Please replace the HEPA filter
regularly to maintain optimal high performance.
It is recommended for optimal performance from the air purifier that it is left
on continually. Under this type of usage, filters will need to be replaced ev-
ery six months. Please visit www.AlenCorp.com to sign up for a filter subscrip-
tion program so that a filter automatically is shipped to you whenever you
want it – every four, six or eight months!
HOW TO REPLACE THE FILTER
1. With the front of the unit facing up, pull up on the lower end of the inlet
grill.
2. After pulling up, push the grill toward the display panel at the top of the
unit.
3. Remove the used HEPA filter by lifting the pull string.
4. Take the new HEPA filter out of the plastic bag and insert it into the air
cleaner with the arrow pointing inward.
5. Insert the top of the inlet grill first and then snap in the lower part of the
grill.
