good replacement

I used the measurements on the system to get a replacement for a spa manufacturer that is out of business. Good replacement and less than Unicell. Came out several inches taller than the 15" indicated but works fine in my spa.

I am gonna be a repeat customer for years to come!!!!

Very hard to find filters.... Customer service were great and on top of it when I told them what I needed.

Excellent Filter at a very good price.

I have used this, bought from you, four times now. It works well and is so reasonably priced that I can just replace it rather than clean it. I like that because my spa stays much cleaner and fresher.

Everything was perfect!

Both items came exactly as ordered. We will definitely order from you again.
