Simplicity Symmetry Post Filter Replacement for S20D & S20P Water Softener Systems - Perfect for Home Water Filtration & Salt-Free Conditioning

This genuine Foam Post Motor Filter fits Symmetry Models S20 D and S20P. This filter was originally included in a filter set, along with a secondary filter for these models, but is now being sold individually. 

We recommend replacing this filter regularly to help ensure your unit does not loose suction or filtration performance. Normal use is every 1 year. If your home has allergen or asthma sufferers, we recommend replacing every 6 months. This is a Genuine Simplicity Part.
