Home Air Purifiers: For large areas, air purifiers using a combination of technologies such as HEPA filters and Ionizers help keep the air clean and fresh.  Be sure to pay attention to the square footage being purified and choose your air purifier accordingly. 

Room Air Purifiers: Like Home Air Purifiers, the best air purifiers for rooms utilize a combination of air purification technologies. 

Commercial Air Purifiers: Commercial and Industrial air purifiers have the ability to handle a larger volume of contaminants when compared to standard air purifiers. 

Allergy and Asthma Air Purifiers: Air purifiers with HEPA and Activated Carbon to help purify allergy and asthma triggers. 

Pet Air Purifiers: For pet allergies and odors, look for air purifiers with HEPA filters, Ionizers, and UV light (preferably a combination of all three technologies). 

Smoke Air Purifiers: Tobacco smoke odors are difficult to remove, but air purifiers with Activated Carbon can help ensure clean air. 

HEPA Air Purifiers: HEPA air purifiers are capable of capturing 99.97% of particles as small as 0.3 microns.  These are extremely powerful at particulate control and are perfect for all-purpose air purifying. 

Ionic Air Purifiers: Ionizers charge airborne particles and remove them from the air you breathe.  They are easy to maintain, silent, and even aid in increased oxygen intake. 

Ozone Air Purifiers: By releasing ozone-enriched plasma into the air, ozone air purifiers reduce indoor pollutants such as dust, mold, bacteria, and chemicals.  These types of air purifiers are ideal for areas with high pollution, such as bars and salons. 

Allergy Furnace Filters: These types of filters are disposable and capable of turning your home into a "whole house" filter.  Recommended by physicians, furnace filters are perfect for allergy and asthma sufferers.
