HTH Spa Care Filter Cleaner Liquid for Spas & Hot Tubs, Deep Cleans & Extends Filter Life, 16oz

After letting the filters soak only 2 hours, they came out really clean. Of course, I sprayed off the loose dirt first. I highly recommend this product!

The filter cleaner worked great like it said it did. i have not had a chance to test the test strips out. all in all everything is great so far. The on-line ordering is really easy.

It was what I need it, good price

Is wonderful stuff for your pool or spa

[This review was collected as part of a promotion.] This filter cleaner has helped keep my filters from becoming dirty so quickly. It is easy to use. If you're having a problem with your filter getting dirty and having to buy new ones all the time, use this.

[This review was collected as part of a promotion.] I really love this filter cleaner! It works amazing! I like being able to just clean the filter instead of having to replace it each time. Once you notice the water pressure decreasing and realize the filter needs to be cleaned you use this product. It's very simple, rinse off the filter, fill a bucket with water and add the cleaner, put the filter in this solution for 3-6 hours and let sit. You will notice a huge difference, it's like putting back in a brand new filter. It saves on having to purchase a new filter and also better for the environment as well as not as many filters being used. It's so easy to do and so effective! I would highly recommend this product!

[This review was collected as part of a promotion.] Does a great job deep cleaning filter in Spa or Pool helping to maintain clarity of the water itself while extending the life of the filter. The difference is noticeable when looking at the filter itself before adding the Cleanser. Can be used with many Spas & Pools. Doesn't leave any cloudiness behind.

[This review was collected as part of a promotion.] This spa filter cleaner works great! Just fill up a container, add the cleaner, and add the filter. You soak it a while, the. We rinsed it off. We were amazed and how much dirt was removed and how much cleaner the filter was after using this product!

So, I saw very little cleaning of the filter that wasn't even that dirty in the first place. But, the bigger issue was the inability to really rinse the chemical off the filter. I still feel that I'm seeing foam from that chemical and we're breathing it in once in the tub it seems. I'll likely end up emptying the tub and buying a new filter because of this. I would not recommend.

Terrible product. Used as per instructions, rinsed the soap off the filter after soaking overnight, but the tub is still foaming after 4 days. Will need to drain and refill 300 gallons of water
