Great site, competitive pricing and quality products. Have purchased through site for years
Filter well and last well over a year in rotation with two sets. Have been buying them since they became available several years ago. Reasonable price at Spa Depot
Quick and fast delivery of a quality product with fair prices
Hot tub filter.
Exact replacement. Easy to install. Lasts longer than OEM.
I bought two of these filters and both clogged within about two weeks of use, one after a fresh tub refill. Soaked both overnight with cleaner and they worked for about a minute before getting clogged again. My Marquis brand filter was going strong for over 2 months.
I had bought these replacement filters prior from Spa Depot and they always worked fine and the price seemed reasonable. This time I thought I would try the Antimicrobial version for the slightly higher cost. I was not sure if this was a real attribute of some marketing, but they have been in my spa for a couple of weeks and seem to work really well. Better than the non-antimicrobial . . . so worth the cost in my opinion.
I am happy with this purchase. The inside of the filter even has a slight lip so my sanitizing stick stays in place. I will be buying another for a backup.
i use these filters in my Marquis Wish spa. I rotate 2 sets of filters every 3 months and my water stays crystal clear.
These filters are affordable, work well in our Marquis spa, and really keep the water clean.
