Consider the Unicel Filter Cartridge to be among your top go-to pool, hot tub, and spa cleaner essentials if you have 1 of those compatible models. Here are some signs it may be time to replace your cartridge: The plastic end caps on your pool cartridge ensure the material stays together. They're made of heavy-duty plastic but can crack over time with exposure to pool chemicals. When they become brittle, they can crack or chip, sending broken pieces through your filtration system and causing equipment damage. Prevent any possible harm to your pool's filtering system by replacing your cartridge as soon as you notice damage on the plastic endcaps. A crushed cartridge is a sure sign it's time for a replacement. Purchasing the correct size from the quality cartridge-makers from Unicel will help ensure this doesn't happen, and can keep your pool running efficiently and safely for years to come.
