SunPurity Mineral Cartridge for Spa Water Treatment

Price was right on.

If you are not using this as your sanitizer, now is the time to start. I love my Sundance Spa which I have had over 10 years. One of the best features is the slot in the gate where this sanitizer goes. No bouncy things around your spa, additional chemicals you have to put in, or those floating gadgets that you have to fill. Open the door, put it in. Being in the gate, it gets the most movement and keeps the sanitizer evenly distributed and moving at all times. You probably should replace every 3 months or so, but I generally go 6 months or so and replace with a cleaning and refill. My favorite spa product for my favorite spa which I use everyday.

I put this in next to my filter. It has made a huge difference in how much chemicals I use. I still put chlorine in after use, but this helps keeps the water clear in between uses. It is great!

I love my spa but don't always to remember to add chemicals when I am not using it for a while. The sunpurity allows for this without having to worry about needing to drain and refill because biofilm formed. A little expensive but so worth it.

Delivered as promised.

Was an exact replacement for my Sundance spa!

I've used a few systems with a couple of different hot tubs, but this works the best, and is the easiest. The best part is, the water always smells clean without any chlorine smell. After making sure the water is properly balanced, I use one of these cartridges every 4 or 5 months, and just add one ounce of Oxidizer and a very small amount of chlorine granules once a week. Even with heavy use, adding a little Oxidizer after each use provides excellent results. No more floating chlorine or bromine tablet dispensers, or constant water balancing.

Great product to keep the spa looking great!
