SunPurity Generic Mineral Purifier Cartridge for Sundance Spas Sun Purity

bought many of these over last 5 years. work great for about 4 months with a minimal amount of chlorine in a small Sundance hot tub. Price is great for the product, seem to have a little less minerals in them than the original ones but half the price and work fine.

I had to use aquarium acrylic glue to put this back together. the corner was crushed on the product and it was partially exposed. So I glued it back together. seems to be okay now. disappointing for what I paid.

Great product! I have tried the "stick" type of sanitizers, but never get the results i get with this one.

Used for our Sundance hot tub so far it’s great plus cheaper than sun purity!

Works perfectly in my Sundance Spa; at a very fair price and shipped quickly.

I have used this for 13 years. It keeps the spa beautiful and clear. Delivery very quick.

This is just like the name brand sanitizer for my hot tub for less money. Easy to install..

Repeat order for my fountain. Works great to keep water fresh and clean, cuts down cleaning to once every 3 - 4 months running 24/7.
