O.F.S. stands for Organic Fiber Sterilization technology.
Independent test results conducted by the CHN Center for Disease Control and Prevention institute for Environmental Health and Related Product Safety show that the O.F.S. filter killed 97.7% of certain airborne bacteria in a mid-size room after 6 hours of operation.
How Neoair Air Purifier Works
The first purification stage starts with the Pre-screening Filter.
Its main function is to capture large particles such as dust, pollen and skin flakes. Another feature of the pre-filter is to preserve and extend the life of the HEPA and Activated carbon filters. By pre-filtering the larger molecules, it shields the HEPA filter from getting clogged.
The 2nd stage consists of a High Efficiency Particulate Air Filter commonly called a HEPA filter. Originally developed by the Atomic Energy Commission, it removes 99.97% of particles down to 0.3 microns in size, almost 300 times smaller than the width of a human hair. HEPA technology is currently the only type of air purification tool recommended by the U.S. Government
