The best way to deliver easy-to-manage, longer-lasting hot tub water is to start with the cleanest water possible. This can be achieved with the Clean Screen Pre-Filter. This one-of-a-kind pre-filter traps organic contaminants, metals (such as copper and iron), and tannins before they are introduced into the spa, so the water is as clean as possible at start-up. It is simply screwed onto the hose before you fill the spa and everything is filtered out as the water runs through the Clean Screen.
Another benefit of the Clean Screen Pre-Filter is that it can be used with any chlorine, bromine or biguanide water care program. Removing contaminants prior to introducing water into the spa helps decrease the need for additional chemicals that would otherwise be needed to treat the water. Adding fewer chemicals means less work for you. Additionally, reduced chemical use can contribute to a lower Total Dissolved Solids (TDS) level, which may help extend the life of the water, making water changes less frequent. So with all of that said, this product should be used each time you fill, refill, and top off your hot tub.
