This inline prefilter reduces sediment, algae, red worms and other impurities in the coldwater supply to doubleprotect household appliances such as washing machines and smart toilets, as well as the water heater. Key benefits Filters sediment, red worms, algae and other impurities to protect washing machines, smart toilets and other appliances from contamination. Helps prevent scale and blockage in the water heater by ensuring cleaner water is heated, extending heater life and maintaining performance. Improves water quality entering showers and fixtures by reducing particulates and impurities. How it works Installed on the coldwater inlet of the water heater, it filters and purifies incoming water before heating. By removing sediment and particles before they are heated to temperatures, it minimizes scale formation and reduces the risk of clogging the inner tank and related components. This simple inline filter acts as a first line of defense for the water heater and connected appliances. Use scenarios Scenario 1: In homes with traditional electric or gas water heaters, install the prefilter on the coldwater inlet to minimize sediment buildup, extend heater life, and maintain consistent hot water performance. Scenario 2: For households with washing machines, place the prefilter on the coldwater supply to reduce sediment and impurities that can affect washing efficiency and appliance longevity. Scenario 3: In homes with smart toilets or other appliances relying on clean water, use the prefilter on the coldwater line to help prevent blockages and maintain reliable operation. Installation note Note: The prefilter is installed on the coldwater line feeding the water heater. It filters and purifies incoming water to protect the water heater. Regular checks and timely filter replacement, as recommended, help maintain performance.
