This company's High Airflow Particulate Air (HAPA) filter media has micro-fiber technology to reduce airflow resistance, which can help create smaller, quieter and more effective appliances. The filter can be incorporated into any appliance that requires air cleaning, including air purifiers, hvac filters and more. HAPA filters are far less restrictive to airflow than HEPA filters and outperforms HEPAs in the filtering of tobacco smoke and oily aerosols. It provides higher cfms and efficiencies and is also more durable than glass micro-fiber.
