1. Replacing the Filter

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.
