Clarathon Premium Ultra Filters are the most effective and durable pool and hot tub spa filter cartridges available. In fact, you cannot buy a better quality filter at any price. Save even more with our generous quantity discounts!

Tips: Keep spares on hand. When you change your spa water, always rotate the soiled filter out with a clean, dry spare. The result is longer filter life and no waiting. Refresh dirty pleated cartridges with Eco Soak or Power Soak filter cleaner (special savings below).
