How Often Should You Clean you Pool Filter
Keeping your pool crystal clear and safe to swim in starts with proper pool filter maintenance. One of the most common questions we get at Orchid Pools is: How often should you clean your pool filter? The answer depends on the type of filter you have, how frequently you use your pool, and the environment around it. In this blog, we’ll break it all down.
Why Cleaning Your Pool Filter Matters
Your pool filter is responsible for trapping dirt, debris, oils, and even microscopic contaminants. If the filter becomes clogged or dirty, your circulation system can’t function properly. This can lead to:
Cloudy or dirty water
Algae growth
Increased strain on your pool pump
Reduced lifespan of pool equipment
That’s why regular pool filter cleaning isn’t just a suggestion—it’s a must for any pool owner in Florida’s warm, humid climate.
How Often to Clean Your Pool Filter (By Type)
1. Cartridge Filters
Recommended cleaning: Every 2–6 weeks
Cartridge filters are common in residential pools and easy to clean. If your pressure gauge rises 8–10 psi above the normal range, it’s time for a rinse. Regular cleaning helps extend the life of your cartridge (usually 1–3 years with proper care).
2. Sand Filters
Recommended backwashing: Every 4–6 weeks
Sand filters require backwashing rather than manual cleaning. When the pressure gauge increases by 8–10 psi, it’s time to backwash. Don’t forget to replace the sand every 5 years or so to keep it filtering effectively.
3. Diatomaceous Earth (DE) Filters
Recommended backwashing and recharging: Monthly or as needed
DE filters provide the best filtration but require more maintenance. Backwash when pressure increases and re-add DE powder after each cleaning. A full teardown and deep cleaning should be done at least once a year.
Factors That Affect Cleaning Frequency
Pool usage – More swimmers = more contaminants
Weather – Rain, storms, and pollen increase debris
Surrounding environment – Trees, sand, and insects all impact filter load
Water chemistry – Poor water balance can clog filters faster
Signs Your Pool Filter Needs Cleaning
Cloudy or green pool water
Weak water circulation or suction
Higher-than-normal pressure on the filter gauge
Unusual noises from the pool pump
Final Thoughts: Don’t Wait Too Long
Regular pool filter cleaning is one of the best ways to protect your pool investment. At Orchid Pools, we recommend checking your filter every week during the swimming season and staying on a cleaning schedule based on your specific filter type.
