They are a good value

Excellent replacement filters, dropped right in, fit perfectly and the price was good.

Perfect Fit
Size: S8M150
Exact replica of name brand, fits perfectly.....we bought and installed these filters at the height of pollen season in middle GA (i.e. pollen hell) and they have been incredible at filtering the pool. The week after we installed them the temps changed dramatically and we fought an early season algae bloom and absolutely would not have won the battle without these new filters. Absolutely a great purchase.

So Far, So Good!
Size: S7M120.
Initially we thought the filters were bad based on recommendation from the service company. We ordered new filters and replacing this set, we discovered they are still in great shape! We washed the set and set it aside for cleaning cycles.

Cracked horribly in 10 months
Size: S8M150
I would give 0 stars if possible. These filters did not last one year before extensive cracking on both filters. I regularly clean, and we have a very light filtering load with pool filters I've designed for our pool size. DO NOT BUY THESE FILTERS. My Sta-Rite filters lasted 2015-2025 before needing replacement due to the bands wearing out. These did not last even 12 months. STAY CLEAR! They did work fine for the first 10 months, so if you are fine with replacement that often, that's up to you.

So Cheap - and So Awesome

Saved about $700 buying these through Amazon instead of direct from store. Great move - they fit perfectly! Pool has been great all summer.

Compatible with Pentair Sta-Rite S7M120
Size: 1 Pack
Replaced the O-ring on my Pentair Sta-Rite S7M120 and it completely stopped a leak I couldn’t figure out. The old O-ring didn’t look worn, but this new one is slightly thicker and sealed everything up right away. Fit perfectly and worked exactly as expected. Definitely a simple fix that made a big difference

Swamp to Lake to Pool
Size: S7M120.
These fit perfectly and our pool is crystal clear again. We're two weeks in and I didn't notice any problems when I cleaned them. They work perfectly. We're first time pool owners (came with the place). Old filters needed replacement (falling apart), trees everywhere, and no waste line. Imagine the worst algae bloom possible. Now times it by 10. We had a swamp. I wish we did this before flockulant. At least we can now see as we vacuum up PILES of dead algae. It legit looks like the bottom of a sandy lake (but we can see it!)
