Phresh_cut_awayPhresh Filters are light weight filters. This is
not only due to the light weight carbon but also to the aluminum
flange and base   The carbon bed is machine compacted. Using
very intense vibrations when filling the filter with the carbon
the filter is filled to the max. So no air leaks or shifting
carbon inside your filter.  Immediately after production the
Phresh filter is bagged and sealed to preserve all the good
qualities during transport.
