O.F.S. stands for Organic Fiber Sterilization technology.

Most filters only capture bacteria, acting like flypaper for the microscopic organisms. But the advanced O.F.S. filter not only snares bacteria but kills it as well.

The O.F.S. filters are soaked in a special neutral, non-irritating organic solution. The compound bonds with the filter media and starts a chemical reaction that destroys certain bacteria trapped on the surface within time after contact.

The technology behind the O.F.S. filter is the first of its kind.

In environments like hospitals or laboratories where cleanliness and sterility are crucial, the new O.F.S. filter technology is an invaluable tool in fighting the spread of disease and infection.

The O.F.S. technology has proven to have broad spectrum antibacterial effects and can restrain growth and reproduction of Gram-positive and Gram-negative bacteria.

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 airborne bacteria in a mid-size room after 6 hours of operation.
