When it comes to pool maintenance, one of the most overlooked—but critical—tasks is cleaning your pool filter. A clean filter not only keeps your water sparkling but also ensures your pool system runs efficiently and lasts longer. But the big question is: how often should you clean your pool filter?
The answer depends on your filter type, pool usage, and environmental conditions. Let’s break it down.
Types of Pool Filters and Their Cleaning Schedules
1. Cartridge Filters
Cartridge filters are popular due to their ease of use and minimal water waste during cleaning.
- Clean Every: 2 to 6 weeks
- When to Clean: When pressure gauge rises 8–10 psi above normal or water flow is reduced
Pro tip: Rinse with a hose regularly and deep clean with a cartridge cleaner every few months.
2. Sand Filters
Sand filters are low-maintenance and ideal for larger pools.
- Backwash Every: 1 to 4 weeks
- Deep Clean Every: 2 to 3 months
Watch for cloudy water or pressure changes—they’re signs it’s time to backwash.
3. Diatomaceous Earth (DE) Filters
DE filters offer the finest filtration but require more upkeep.
- Backwash Every: 1 to 3 months
- Manual Clean: 1 to 2 times per season
- Recharge DE Powder: After every backwash
Remember to handle DE powder with care and dispose of it responsibly.
Factors That May Require More Frequent Cleaning
- Heavy pool usage
- Storms or high winds
- Nearby trees or landscaping debris
- Algae blooms or chemical imbalances
If any of these occur, inspect your filter right away.
Signs Your Pool Filter Needs Cleaning
- Water looks cloudy or murky
- Pressure gauge reads 8–10 psi above baseline
- Poor circulation or weak return jets
- Auto cleaner isn’t moving efficiently
Final Thoughts
Routine filter maintenance is essential for a clean, healthy pool and a long-lasting system. Whether you’ve got a cartridge, sand, or DE filter, stick to a schedule—and don’t wait for your water to tell you it’s time.
If you’re unsure or want it done right, consider hiring a professional pool service to keep everything running smoothly.
