FreshWater Clean Screen Pre-Filter

The FreshWater Clean Screen Pre-Filter attaches to your garden hose and filters out organic contaminants, metals, and sediment before water enters your spa. Best maintenance choice you can make for water quality is one most owners overlook entirely: starting with the cleanest possible fill water means less work managing chemistry afterward. Fill water — whether from municipal supplies or private wells — almost never comes out of the hose perfectly clean. Municipal water contains chlorine residuals, occasionally trace iron and copper from aging pipes, and sometimes mineral debris stirred up from the system. Well water frequently carries iron, manganese, sulfur, sand particles, tannins from organic matter in the aquifer, and other contaminants that vary wildly by region. Every contaminant you put into your spa is one you'll have to manage with chemistry later. The Clean Screen pre-filter is a single hardware purchase that pays dividends across many fills. One unit lasts approximately 5,000 gallons — that's around 10 complete fills of a typical 500-gallon spa, or 5–6 fills of a 1,000-gallon swim spa. Spread the cost across that many water changes and the math is favorable for any owner, but it becomes nearly required for two situations: Well-water fills — variable mineral and metal content makes pre-filtering nearly essential Salt-system spas — the year-long fill cycle gives any contamination a full year to cause problems Pro Tip: The Clean Screen filters metals (iron, copper, manganese), organic contaminants, sand, debris, and tannins. It does not filter phosphates. If you suspect high phosphate fill water — common with municipal supplies that use phosphate-based corrosion inhibitors — you'll need to test with FreshWater Phosphate Test Strips and use a phosphate remover separately. The two issues are addressed with different products. Brand FreshWater®
