TFP (Turbulent Flow Precipitator) Technology removes health threatening particles from the air far more effectively than most other residential cleaners. It operates continuously at maximum efficiency without the need for constant adjustment and cleanout. Unlike some air cleaners, it introduces absolutely no ozone into your home. It cleans the air throughout your home, benefiting all the family, all the time. The TFP allows air to circulate freely, without putting any extra load on your air distribution system.
