H2X Swim Spa Hot Tub Filters
We offer a variety of factory direct OEM replacement filters for the following H2X Swim Spas: Challenger, Therapool and Trainer.
The H2X Swim Spa uses two types of replacement filters: H2X filters and the H2X Eco Pur filter. Master Spas Eco Pur filtration is patented technology that ensures your water is above all industry standards, and it should be replaced every 6 months. You can order the H2X filter individually or in a filter set for more savings.
If you are looking for a mineral cartridge replacement, refer to the Master Spas Eco Pur Charge Filter, as that is the filter cartridge you will need to use going forward.
For H2X swim spa filter questions (because we know this can be confusing), feel free to give us a call at anytime at 855-308-2149 and we will help you find the correct filter! When you call, please have the year, make and type of Master Spa you own to make the process easier.
Eco Pur Charge filters by Master Spas can help reduce your chlorine usage by up to 75%, while also extending the lifetime of your spa or hot tub. The new Eco Pur Charge Filter is the replacement for all previous Eco Pur Mineral cartridges for Master Spas hot tubs.
