Clarathon Premium Ultra Filters are the most effective, durable hot tub spa pleated filter cartridges. Clarathon uses the best polyester filtration media that money can buy. The result is longer filter life and better water quality. In fact, you can expect up to 33% better filtration than some other brands which may look about the same, but use cheap filter media. An added bonus: Our sharp pleat folds increase water flow rates while making cartridge cleaning easier.
