Home air purifiers are designed to rid the air in your home of dust, pollen and other potential irritants. There are three basic types of home air purifiers: ionic, electrostatic and HEPA.
Ionic air purifiers can be effective in dealing with particulates, some viruses, bacteria and smoke. They work by causing particles to clump together and fall to the ground.
Electrostatic air purifiers can be effective against particulates, some odors, and some gasses and allergens but not viruses and bacteria. They require electricity and work by using charged plates to collect pollutants.
HEPA air purifiers can be effective at trapping hair, dust, pollen, particulates, mold spores, pet dander and some bacteria. They also require electricity and work by using a filter, which must be replaced every 12 to 18 months.
At Walmart, you'll find a wide selection of home air purifiers at Every Day Low Prices. For tips on choosing the best one for you, check out our Air Purifier Buying Guide.
