Lifegard Replacement filter pad material
is bonded to keep its original shape. It has superior filtration with uniform
and consistent material and filters all size of particulate matter.
Make a pattern out of cardboard or paper to match the size of your filter box
opening. Place a pattern on the filter pad material and cut 1/4" larger on all
sides for a snug fit. Insert pad into filter Blue side up. For even better
filtration, cut 2 pads and sandwich a bed of Lifegard Activated Carbon between
the 2 pads.
