First, remove old air filter, Next, insert the carbon filter into the duct work behind the grille air filter slot..Then install the second white furnace filter in the return air grille filter slot.

You now have a two step filter process. The white pre-filter captures dust, pollen and other particles. The air then filters through the second carbon filter that captures gases and odors. This two step system reduces pollution significantly in your home, clinic or other business.

For the best pollution control, change the carbon air purifier filter at least once per year. The white allergen filter needs replacement at least every three months. More polluted environments may require more frequent changes of both filters.

Safe Home Air Purification System includes 4 pre-filters that fit the cold air return grille slot and one carbon filter that fits into metal ductwork behind the grille.  Each one inch white pre-filter is pleated and has a continuous metal diamond pattern on all pleats. Filters are made to fit into a metal return air frame. Always install so that return air flows through the pre-filter first.
