Factory replacement filter cartridges for all Hot Springs, Tiger River, Hot Spot and Solana spas!

Need new spa filters? We have all the right sizes and shapes for your make and model. Our factory original replacement filters are designed specifically for Watkins Manufacturing makers of Hot Spring, Tiger River, Hot Spot and Solana spas. Specially designed filters are critical since Hot Spring spas filter 100% of the water 100% of the time. The filters play a key part in Hot Springs' "hydraulically balanced" systems. Hydraulically balanced means there is one square foot of filter fabric per one gallon of water flowing through their systems. This equation is doubled in the new patented Tri-X ceramic filters. Balanced water flow makes efficient filtering, perfect jet pressure and a happy jet pump.

We have genuine OEM factory replacement filters for every Hot Spring, Tiger River, Hot Spot & Solana spa ever made!			Have you seen theHot Spring Tri-X® ceramic filters? You can just pop them into your dishwasher (no soap and the drying cycle off) and Voila! Cleaned filters.
