An electronic air cleaner is 40 times more effective than a standard throwaway filter in removing unwanted particles from your home. Particles such as pollen, dust, bacteria, tobacco smoke, cooking smoke, animal hair and dander prevent your indoor air from being as healthy as it could be. An electronic air cleaner with a washable electronic cell is up to 99% effective at removing these airborne particles. An electronic air cleaner also protects the operating efficiency of your heating and air conditioning system and keeps your furniture, drapes, carpet and walls cleaner, as well.
