Replacing the Filter on a Pollenex Whole House Water Filter

The filter housing is a Pollenex PureWater 99. I'm using a Silt & Sediment Filter Cartridge, Pollenex Model #FWP37. The cartridge fits Pollenex models WPV65, WP51, WP40, and also fits Cuno Aqua-Pure, Fulflo, Filterite, Omni, Sears and most other standard size water filters.
