HEPA Air Purifier Review

HEPA air purifiers are rated the best by every independent air purifier review we have seen as well as by leading goverment agencies such as the American Lung Association and EPA. This is because the HEPA filter media has been tested to remove the highest percentage of airborne particles and generally improves over time whereas filter-less and permanent filters decrease in performance. 

Whether you suffer from allergies, mold, pollen, dust, or pet dander, etc our strong recommendation is that you select a HEPA based home air purifier to get the cleanest air possible.  While not the lowest cost you definitely get the best performance and that is because the HEPA filter captures the broadest range of particle sizes. 

Be sure to also review the noise levels as it may not be reasonable to operate an air purifier in a room if it will be too loud.  Decibel levels can be tricky to understand however when comparing models keep in mind that the noise level doubles for every 10 decibel increase in noise - so a 60 decibel air purifier is twice as loud as a 50 decibel air purifier. 

If you are looking to remove gases, odors and smoke you will want to purchase a purifier with either a lot of carbon or significant carbon filter surface area.
