We utilize the Sirona™ Simply product line for a bromine-free, chlorine-free solution designed to keep cold tub water sparkling clear and sanitary, with no chlorine odor or dry skin. Our kit works regardless if you are using your Edge Tub at 37*F or 107*F or anywhere in between. Sirona’s Oxidizer breaks down organics such as body oils while the EPA-regulated Sanitizer provides excellent bacteria control as well as protects against staining and discoloration due to metals.

*ATTN:  If the filter housing on the back of your cold tub chiller is BLUE you must purchase the BLUE specific filter option. If the filter housing on the back of your cold tub chiller is CLEAR you must purchase the CLEAR specific filter option. Failure to do so may cause chilling unit damage and malfunction.

*Assuming 7 uses per week. Oxidizer and Sanitizer usage may increase with additional persons or more frequent plunges. Filter longevity can be extended by rinsing off prior to entering water, especially after exercise.

6 pack 20 Micron Pleated Cartridge filters. *ATTN:  If the filter housing on the back of your cold tub chiller is CLEAR you must purchase this specific filter. Failure to do so may cause chilling unit damage and malfunction. If your filter housing is blue, please click HERE.


Our 20 Micron Pleated Cartridge filter keeps the water in your cold tub clean and filters out dirt, sweat, hair, and debris.

To keep your ice bath water crystal clear, it’s important to change out your filter every 2-4 weeks *depending on frequency of use, volume and water chemistry.

To check if your filter needs to be changed, please see weekly maintenance video here.

*Our filters are designed specifically for use with Edge Chillers. Other filters may not fit properly and cause damage to the product, and will void the warranty.
