    Filter


    A Filter is any porous device that allows the passage of air but traps air born particles, thus cleaning the air.

    HEPA Filter

    HEPA stands for High Efficiency Particulate Air. HEPA filters were developed during World War Two as a safety device for the Manhattan Project, the American effort to develop nuclear weapons. HEPA filters use glass fibre as a filter and can clean 99.7 per cent of particles above 0.3 microns in diameter. Though brittle, these filters are now widely used in a variety of filtration devices, and are widely considered to be the best air filter available to the public.
