Prompt delivery, outstanding filter
The filter fit perfectly and is performing well. I also needed some PVC fittings to stop a leak in my spa they also were the correct parts to fix the problem, the technical staff was very helpful in selecting the proper fittings.
Very satisfied with the filter and quick/easy ordering. Will use Spa Depot in the future.
The product was exactly what I was looking for.
this filter is used on a older spa and so far its been working well
After running the new filter for two days, my water looks like it was just changed. The cloudiness is gone. Yes, this is way more expensive that the white paper filterm but the results are well worth it.
Good product Cheaper to buy than my regular supplier
Thank you for the excellent replacement filters for my Marquis Spa! They fit perfectly and have more filtering surface than the original ones! The Spa Frog chemicals make the water perfectly balanced and a joy to use.
Great material and construction
