Filter Cartridge Cleaning and Care

Note: Unplug pump from wall outlet before removing and / or replacing filter canister.

1. Once your filter cartridge is removed from your SFS / SFX / RP / RX / CP - 2000c canister, it’s time to rinse. Use a garden hose to rinse debris from between the pleats, moving from the top of your filter to the bottom. The sprayer on your kitchen sink also works. In both cases, adjust the water flow so not to damage the filter. Try to remove as much debris as possible. Flip the filter 180 degrees and, again, hose from the top down.

2. Inspect the filter for physical damage. The paper pleats might be torn from debris or over use. The plastic at the top and bottom may be worn, which makes a good seal impossible. Replace if necessary. You can purchase filters at our online store or by calling Polygroup customer service department at 1-888-919-0070.

3. For the next step you’ll need a bucket or a large trash can that’s big enough to hold your filters. This step will help you remove sunscreen, lotions, perspiration and oils. In order to do this, you’ll need to soak the filters in a store-bought filter cleaner, Trisodium Phosphate (one cup per five gallons of water) or dishwasher detergent (one cup per five gallons of water). Be sure to soak the filter cartridge for 1 to 10 hours. The longer you soak the filter, the better the cleaning.

4. Once your filter cartridge is done soaking, you’ll want to shake the filter while it’s still submerged to help loosen debris. If you still notice debris in between the pleats, you can repeat the rinsing steps. Be sure to remove all cleaning solutions and oils before proceeding.

Finally, give the filter cartridge one final rinse to spray off the acid/water solution. When reassembling your filter cartridge, it is recommended to apply a drop of silicon based lubricant to the o-ring to help extend its lifespan.


Keep extra filters on hand. When one filter is removed from a canister system to be cleaned, use the extra filter. Rotate the filters each time you clean one. A properly maintained pool would need to clean/replace filters once every two weeks or so dependent on local conditions.

When a filter is cleaned, inspect it, just as with a car air filter, it is easy to determine when it is time to discard a filter and replace it. When your last new filter is placed into a filter canister, it is time to buy more. You can purchase filters at our online store or by calling customer service at 1-888-919-0070.
