Sand, cartridge, or DE — each filter type has strengths. We help you choose the right one for your pool, size it correctly, and install it so your water stays crystal clear with minimal maintenance.
If chemistry is right but water won't clear, your filter likely can't keep up anymore.
Pressure 8–10 PSI above normal even after cleaning means the filter media is exhausted.
Needing to backwash or clean every few days instead of weekly signals a failing filter.
Cracks in the housing, broken internal manifolds, or crumbling filter grids mean it's time.
Cartridge filters are our most popular recommendation — they offer excellent filtration with minimal maintenance. DE is best for pools that demand the clearest water. Sand is the budget-friendly choice. We'll assess your pool and recommend the best match.
Cartridge elements every 1–3 years, sand media every 5–7 years, DE grids every 7–10 years. The filter housing/system itself typically lasts 10–15 years before needing full replacement.
Most filter replacements or new installations take 2–4 hours. If significant plumbing changes are needed, it may take a full day.
