Spa Marvel Filter Cleaner

I have used many different filter cleaner products. Spa Marvel is by far the best, my filters are cleaner than ever!

I was referred to this product by a large number of hot tub owners and service personnel and I can certainly understand why. The product is easy to use, cleans extremely well, works reasonably fast and doesn't require a PhD in chemistry to utilize. As our Wellis hot tub has three filters, this is an extremely beneficial product and has absolutely made a difference in our monthly filter servicing.

Thanks the only hot tub filter cleaner we use. We place the recommended amount in a 5 gallon pail and allow filters to soak overnight. Rinse thoroughly and allow to dry. It is harsh on your skin so avoid touching the water when soaking use a wooden spoon if you need to adjust filter in bucket.

I have maintained my hot tubs for over 20 years and I am so disappointed that it took so long to find the best and most economical cleaner. Two capfuls in a five gallon bucket, an overnight soak, jet spray afterwards, (I know that the directions say to spray before the soak but this worked too.). And the filter looks very white and clean. No foam taking several rinses to remove. WOW!

Does a wonderful job as specified and does not cause excess foam like other brands

Certainly not the cheapest, but it cleans the filters better than other cleaners I tried. Highly recommend.

Ordered 4 bottles of this for current and future uses. After leaving filter in solution for over 48 hours, the granuals never dissolved and are at the bottom of the water. Filter is still dirty and looks no different from when I started the process. Cannot return the product for a refund because it contains chemicals according to policy. Bad investment.

I belive it’s over rated don’t really see a big difference between product and just water when cleaning

We have used a few brands, but this one appears to have better results. We were quite surprised after soaking the filters, that the water was more dirty than usual and the filters came out looking more clean.

This product works great. I am very happy with it

Spa marvel is a must if you own a hot tub,it's simply amazing..with this product you can keep chlorine levels very low ..plus they have awesome customer service

Seems to do job , I thought a little expensive for the quantity received

I will never buy another filter cleaner for my hot tub!! I love this whole line of Hot Tub products!
