If you're noticing your pool water isn't looking as clear and sparkling as usual, it may be time to replace your pool filter. With the Sta-Rite System 3 S7M120 pool filter, there are 2 filter cartridge parts. If you need to replace the small, inner filter of your Sta-Rite System 3 S7M120 pool filter pump, grab this replacement part from Sta-Rite. The Sta-Rite System 3 filter allows you to avoid replacing your filter cartridges for longer, but the day will always come. For most multiple cartridge filters, you only need to replace the filter cartridges once every 3 years. Whether it's routine maintenance or a decrease in filter performance, you'll want to remove both the System 3's inner and outer filters to inspect for damage, disrepair, or trapped, large debris. If the culprit is the inner filter, you replace it with this. This replacement pool filter cartridge is specifically the inner filter (model number: 25021-0200S) of the System 3 S7M120. It measures 11 inches in diameter and 30.5 inches tall and is only for use in this system. Simply stop the water flow to your filter pump, open the lid, and remove both filters. The inner filter should remove by twisting and lifting. If you need to replace the outer filter as well, the compatible outer filter cartridge (model number: 250220201S) is sold separately. With all the necessary parts, the System 3 filter cartridge keeps pools with an area up to 100 square feet clean and clear. Reduce mineral, scale, oil, and rust build up in your pool with this handy pool filter. This means your pool water will be clean of debris and impress your guests with its shine. You'll appreciate the removal of minerals and oils which will help your skin feel softer and avoid irritation. Routine maintenance isn't anything to be afraid of. Your pool will be back to it's normal sheen in no time with the System 3 S7M120 Replacement Inner Pool Filter Cartridge from Sta-Rite.
