Product Description

O.F.S. stands for Organic Fiber Sterilization. This patent pending filter media is based upon phytopharmaceutical research and is really a breakthrough in air purification. # Most filters capture bacteria, but advanced OFS technology kills it as well. OFS filters are bonded with a patented media that creates a chemical reaction and kills trapped bacteria. Independent tests conducted by the CHN Center for Disease Control show that the O.F.S. filter killed 97.7% of airborne bacteria in a mid-size room after 6 hours of operation. A HEPA filter removes a minimum of 99.97% of contaminants at 0.3 microns in size. A micron is One one-thousandth of a millimeter. To help you better understand something that small consider the following example. A human hair is about 60-75 microns in diameter. Particles under 35 microns in size can't be seen with the naked eye. Pollen is in the 10-100 micron size range with dust in the .5-5 micron range. Particles under the 5 micron size are the most troubling for asthmatics since that is the ideal size to penetrate deep into the lungs.
