For those suffering from allergies or asthma you may be considering an indoor air purifier to help with your problem. A HEPA filter will be the most recommended type of filter. At present, this is the go-to type of air purifier for anyone looking to cleanse the air in their home of airborne allergens. Many other types of purifiers do cleanse the air as well but none will be as efficient for airborne allergens as a HEPA is.

HEPA stands for High Efficiency Particulate Air. Anything with the title HEPA should be able to eliminate 99.97% of allergens down to .3 microns at a minimum. This includes airborne allergen particles such as Pollen, Pet Dander, Dust, Mold Spores, Smoke and more. Unfortunately, there are many “HEPA” filters out there that are not up to par so be sure to read through specs to make sure it says “minimum” and not “up to” that much. A HEPA filter by itself will do a great job, but there are a few other filters that can be included along with the HEPA in order to make it even more efficient. Be sure to take a look at these extras when shopping around for air purifiers.

An Activated Carbon Filter will help clear the air or odors and toxic gasses such as smoke, fumes, chemicals and more. A HEPA filter is unable to capture these so this would need to be included if that is something you wish to be taken care of.

Another is an Antibacterial Filter. This comes in a couple forms; one is when the HEPA filter itself is treated with chemical agents in order to kill any harmful micro-organisms that try to pass through. Another is a UV lamp that is inside the purifier that sterilizes any of these pathogens that pass over the light.

Any of these combinations will be very helpful to anyone looking for a solid indoor air purifier. If you do not need all the extra bells and whistles be sure that they are not included as they will cost more and the filters can be very expensive.
