Your pool filter is the heart of your pool system—it keeps the water clear, safe, and free from debris. But like any piece of equipment, it needs regular care to perform at its best. The big question pool owners often ask is: how often should you clean your pool filter?
The answer depends on the type of filter you have, how often you use your pool, and your local environment. Let’s break it down.
1. Cartridge Pool Filters
Cartridge filters are popular in residential pools thanks to their efficiency and ease of use.
- Routine Cleaning: Every 2–6 weeks.
- Deep Cleaning: Soak in a filter cleaning solution every 3–4 months.
- Replacement: Every 2–3 years (depending on wear).
- Tip: Clean sooner if your pressure gauge rises 8–10 PSI above normal.
2. Sand Pool Filters
Sand filters require less hands-on work but still need attention.
- Backwashing: About once a month or when the pressure gauge shows a rise of 8–10 PSI.
- Deep Cleaning: Every season or two using a sand filter cleaner.
- Sand Replacement: Every 3–5 years.

3. Diatomaceous Earth (DE) Filters
DE filters provide the finest filtration but need more frequent maintenance.
- Backwashing & Recharging: Every 4–6 weeks.
- Full Cleaning: Take apart the filter and clean grids 1–2 times per year.
- Powder Replacement: Add new DE powder after every backwash.
4. Other Factors That Affect Cleaning Frequency
Sand filters require less hands-on work but still need attention.
- Backwashing: About once a month or when the pressure gauge shows a rise of 8–10 PSI.
- Deep Cleaning: Every season or two using a sand filter cleaner.
- Sand Replacement: Every 3–5 years.
2. Sand Pool Filters
- Heavy Pool Use: More swimmers = more oils, lotions, and debris.
- Florida Weather: Storms and rain can clog filters faster.
- Surroundings: Pools near trees or landscaping require more frequent cleaning.
Keeping your pool filter clean is essential for clear water, healthy swimming, and long-lasting equipment. By following the right schedule for your filter type—and paying attention to pressure gauge readings—you’ll avoid cloudy water, algae, and costly repairs.
