Although still in development and not yet commercialized, the beneficial properties of our NanoCeram water filter media have been transferred to air filtration.

By enlarging the pore size of the water media from about 2 to about 20 microns, NanoCeram-Air’s pressure drop is competitive with that of HEPA (high efficiency particulate air) media. Yet this media is very effective at filtering microbes and even aerosolized virus.

Studies at the University of Florida show that once a virus becomes attached to the nano alumina air media, its rate of re-aerosolization is about 3 orders of magnitude less than three other HEPA’s that were tested. The affinity for virus to attach to the media out of an air stream provides an exciting opportunity for the development of substantially improved surgical as well as pandemic flu masks. And when used for collective protection as in an HVAC system, pleated filters would provide substantial virus and bacteria retention for hospitals, in biological hoods and in biopharmaceutical manufacture.

NanoCeram-PAC has a sister product for use in air. AirPAC™ uses the same ultrafine carbon and keeps it suspended in the nano alumina structure. Because of its very small size, the surface to volume ratio is highly effective at removing chlorine and other physiosorbable gases. Yet its particulate removal capability is as effective as NanoCeram-Air. The resulting product is a chemical-biological filter capable of adsorbing a variety of toxic gases while at the same time can retain sub-micron aerosols with high efficiency.
