Air cleaner is a term commonly used to refer to any device that reduces pollutants or airborne contaminants from the air in a home. It is designed to reduce the impact of air pollutants on the air quality in a room and can be used to reduce the effects of allergies.

Air cleaners come in a range of styles and sizes, depending on the purpose and size of the area that needs to be cleaned. The most common type is the electronic air cleaner, which uses a HEPA filter to capture dust, pollen, and other particulates from the air. This type of air cleaner is usually used in bedrooms, living rooms, and other areas where airborne allergens are a concern.

Other types of air cleaners include activated carbon air purifiers, air ionizers, ozone generators, and ultraviolet germicidal irradiation systems. Activated carbon air purifiers work by trapping odors and other airborne pollutants in a layer of activated carbon particles, effectively removing them from the air. Air ionizers work by emitting negative ions into the air, which attach to airborne allergens, such as pollen and dust, and make them heavy enough to fall out of the air. Ozone generators use ozone gas to reduce the concentration of volatile organic compounds and other air pollutants. Finally, ultraviolet germicidal irradiation systems use UV-C light to reduce the concentration of microbes, such as bacteria and viruses, in the air.

Overall, an air cleaner is a great way to reduce the impact of airborne allergens and pollutants on the air quality in a room. By choosing the right type of air cleaner for your needs, you can enjoy fresher, cleaner air.
