Aprilaire's air cleaner uses the same types of filtration as HEPA filters, but with a lower restriction to airflow. This means you can filter all the air moving through the furnace. Air can be cleaned throughout the entire home, not just a single room. The complete line of Aprilaire air cleaners offers units for general air cleaning needs and an electronic air cleaner that is the most efficient (non-HEPA) residential air cleaner on the market. 2. When should I change the media?The air cleaner media in the Model 2200 can last from 6 months up to 2 years.
