HEPA air filter systems?
The problem there is that they can only clean the air that actually passes through the filter, so they can only purify a portion of the air in a single room. However, most of the airborne particles in a single room will not line up single file and pass through a stationary filter, let alone an entire home. They also cause noise pollution, waste hundreds of dollars a year in electricity, are limited to collecting particles over .30 microns, and feature costly replacement filters. Our systems are designed to treat all the air in one room or area up to 270 sq ft. (15′ x 18′). Using multiple units is not only the best way to purify the air in your house, it’s the only way!
