Alen® Air Purification
Only Alen offers multi filtration technology; HEPA, Ionizer, UV, Silver 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;
True HEPA Filtration
High Efficiency Particulate Air (HEPA) filters can remove at least 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 viruses and of course larger items such as dust, pet dander and pollen from the air.
This is the same technology as recommended by the US Department of Homeland Security to remove harmful airborne particles in a terrorist threat. Tested at over 1,000% better than the leading ionic air purifier and up to 50% better than leading HEPA type air purifiers by the world's leading independent test lab (yes, we are really that good).
UV Light (ultraviolet)
Our UV light on the A375UV has been tested to eliminate over 96% of airborne bacteria. To see how well the A375UV did in testing click here.
Bacteria are single cell microorganisms that exist everywhere. They are often 0.2 to 5 microns in diameter and most do not create an issue for people. But the ones that can present problems are pretty bad problems:
Healthy environments have higher levels of negative ions, so in our commitment to superior indoor air quality all of our purifiers have negative ionizers. A report from Cedars-Sinai shows that some pollen and dust particles have a positive charge and "negative ions generally lead to favorable effects, and many individuals experience relief from their respiratory allergies." The Geophysical Institute of the University of Alaska Fairbanks found that computer CRT monitors create a surplus of positive ions and the addition of negative ions resulted in a reduction of headaches from the test subjects.
The majority of air purifiers with an ionizer create negative ions, which means they have a negative electrical charge. 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 negative 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.
Our A375 UV is best in class and only air purifier out there 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 problem 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.
The common indoor sources of VOC's are paint, carpeting, copiers/printers, laminated furniture, wood preservatives, paint thinner, glues, permanent markers, cosmetics and certain aerosols and plastics. If there is not sufficient ventilation with the outdoor air and VOC's are present, the indoor pollution levels can be up to 10 times higher than the outdoor air according to the EPA. The A375UV includes UV-PCO(UV Photo Catalytic Oxidation) technology to reduce the levels of VOC's. The interaction of UV-C light and a permanent titanium dioxide (TiO2) grid serves as a photocatalyst to carry out hydrolysis (ie.to break water into hydrogen and oxygen). As TiO2 is exposed to UV light, it becomes increasingly hydrophilic; thus, it can be used reduce concentrations of airborne pollutants such as volatile organic compounds into harmless elements. Ya, we pack a lot of technology into our little air purifiers! As a safety feature, the UV-C lights and titanium dioxide grid are located on the inner most section of the A375UV to prevent the user from coming into contact with the rays of the UV lights.
