What types of air filters do you know besides activated carbon filters?

Ultra Violet (UV)


Air purifiers using this technology have a UV lamp installed inside of them; as microorganisms pass by the UV rays radiated from the lamp, cellular or genetic damage occurs, destroying the microorganism. Although UV technology is effective at killing viruses and bacteria, it is best used with a filter system ahead of the lamps. Without a filter system, too many microorganisms get shaded from the light by particulates.ningxia activated carbon


Negative Ion


Negative ion air filtering technology has proven to be less effective than others because it simply masks the polluted air as opposed to actually cleaning it. This type of air purifier does not have the ability to absorb or dispose of the harmful contaminants in the air. The negative ion simply takes the airborne particles out of the air and transfers them to walls and other solid things in the room. When stuck to walls and other surfaces, they have the ability to become re-circulated back into the air. For this reason, I do not recommend negative ion filters.




Ozone air purifiers produce the gas ozone (O₃). Health professionals have refuted the claims made that these devices are safe, and no agency of the federal government has approved of these devices. Exposure to ozone may ignite asthma symptoms and a high enough level can even scar the lungs. Many of the chemicals found in indoor environments take months or years for ozone to react, making them virtually ineffective. Ozone does not remove particles such as dust and pollen. Obviously, I do not recommend ozone filters.




We’ve all heard this term (which stands for High Efficiency Particulate Arrestance), but probably don’t know exactly what it means. HEPA filters must trap at least 99.97% of all particles larger than 0.3 microns; many of the particles caught in a HEPA filter (including many chemicals) are so tiny they can’t be seen with the naked eye. HEPA filters also trap mold, viruses, and bacteria, so they create a more sanitary environment, and of course they also trap larger particles that can cause lung irritation. (Side note: Make sure your vacuum cleaner is a HEPA-sealed model, too.)


Activated Carbon


Activated carbon filters are comprised of trillions of molecular sized pores that have high absorbent and chemical bonding ability. They are very effective at capturing pollutants like chemical emissions, gases, tobacco smoke, and odors. Once captured, these pollutants are not released back into the air. Activated carbon filters are very helpful to people with Multiple Chemical Sensitivity (MCS) because they absorb formaldehyde, which is found in the adhesives used in carpeting, wood paneling, and upholstered furniture. Fragrances, as well as many chemicals found in household cleaning products, are also removed from the air, making the environment much more breathable, especially for babies, children, the elderly, and those suffering from

Informative article about the types of air filters besides activated carbon filters that enhanced my knowledge I have been finding useful material about this topic to write whereas I thought to just buy assignment online yesterday but now I think I can write well.Thanks for posting this
