Keep your AquaRest spa running clean and clear with this replacement filter cartridge, engineered specifically for the 2015-and-newer AquaRest Discover Collection (AR150, AR300, AR400, AR500, AR600). Pleated polyester filter media traps dirt and debris, while rust-resistant, mold- and mildew-resistant, antimicrobial construction keeps the cartridge performing between changes. Compact and lightweight at 7.25"H x 5.5"W x 5.5"D, it drops straight into your existing filter housing with no tools and no assembly required. For best spa water quality, rinse the filter with water regularly and replace it every 3 months. This filter is designed exclusively for the AquaRest Discover Collection and is not compatible with other branded hot tubs or the current AquaRest DayDream Collection.
