How It Works

The AirPura HEPA Filter with Metal Caps is one inch thick and includes over forty square feet of true HEPA material, with ten pleats per inch. This HEPA filter is capable of trapping up to 99.97% of the particles in the air .3 microns and larger. Metal caps make it one of the most inert and environmentally friendly HEPA sealing systems on the market. Air filters typically have plastic caps, which can potentially off-gas, creating problems for those who are chemically sensitive. The Airpura HEPA filter should be changed every two to five years for optimum filtration efficiency.
