A central air cleaner is a device that is used to filter and purify the air in a home or building. It is typically installed in the central air conditioning system and works by drawing air from the home or building and passing it through a series of filters to remove contaminants such as dust, pollen, mold, and other allergens. The air is then returned to the home or building, purified and free of pollutants. Central air cleaners are a great way to improve indoor air quality and can help reduce the risk of respiratory illnesses and allergies. They are also an effective way to reduce energy costs by eliminating the need to run air conditioning systems at full capacity. Central air cleaners are an important part of any home or building’s air filtration system and should be regularly maintained and serviced to ensure optimal performance.
