Second time I have bought from you and as always great products.
Great descriptions to ensure you are getting the correct products. Fit perfectly in my older spa that was hard to find filters and parts for. Fast shipping as well. Highly reccomend!
I buy all my hot tub supplies here.
Keeps my old hot tub running clean
customer service was great
These work great and very reliable
I HAVE BEEN PURCHASING THESE FROM SPA DEPOT FOR YEARS
These filters were useable. They are not a great match for my spa... but useable.
Our spa is 15 years old and the parts fit perfectly
