Your ad was the ONLY one that had the CORRECT dimensions. I was having a lot of trouble finding this filter due to the errors on other sites. Thank you for your attention to detail. This is used on our Maxx hot tub.
Good quality filter at a reasonable price
This model of filter is so easy to reorder & so easy to replace in my hot tub!
Used in my hot tub…
Have had a hard time finding this spa filter, and was pleased to find it at this dealer. It arrived quickly and in good condition. It is the perfect replacement for our old filter, and we will use this dealer again.
I use this product multiple times by cleaning and disinfecting it and letting it dry then use it again they are very strong and last
Sometimes it's hard to know exactly what you need especially when ordering replacements for old filter from older or custom models spas. This site allowed me to do some measurements and the filter that came was ""Spot on."" Thanks!
Fast shipping and good price. The filter fit and seems to be working well.
Great filter fits perfect excellent price
I purchased this as a less expensive option for the name-brand filter. The filter itself looks to be of the same quality as the branded version. The fit of the housing wasn't quite as good, but still acceptable once the cover was snapped on. Overall it is a very nice option for our hot tub.
