The Air Knight® Ionized Particle Gather (IPG) Air Purification System uses a unique bi-polar ionization system providing your air with both positive AND negative ion technology that encourages particles in the air to gather together, making even your existing air filter system better and more efficient than before. In addition to the IPG feature, PX5 technology consisting of UV light energy combined with a 5-metal, quint-metallic core, purifies the air with active air scrubbers. The high air flow design ensures that your IPG can handle the air volume from todays high SEER and commercial HVAC systems. These technologies combine to make the Air Knight® a virtually maintenance free unit that reduces odors, air pollutants, VOCs (chemical odors), smoke, mold, bacteria, and viruses.
