FAQs

Each filter type has its benefits. Cartridge filters are low-maintenance and energy-efficient. Sand filters are cost-effective and easy to use. DE filters offer the finest filtration but require more upkeep. The best filter depends on your pool size, usage, and water quality goals.

Cartridge filters should be cleaned every few weeks or when pressure rises 8–10 PSI above normal. Sand and DE filters require backwashing, typically once a month or as needed based on pressure readings.

If your pool water remains cloudy despite proper chemistry, or if the filter pressure stays high after cleaning, it might be time to replace the filter media or the entire unit. Cracks or leaks in the housing are also signs of wear.

Some filters are designed specifically for above-ground or inground pools, while others are compatible with both. Check the filter’s flow rate and pool size compatibility before purchasing.
