Guard 7 air filter media is constructed using 5 layers of progressively
finer medical grade cotton gauze, combined with 2 layers of
non-woven synthetic polyester fabric with random porosity. The
result is high-performance air flow with the filtration efficiency
of a heavy-duty filter. This media is so unique it was granted
US patent 6,811,588 (the only filtration media of its kind to
be granted a U.S. patent).
