Optimum Pool Technologies Compatible Replacement Filter Cartridge Kit for System 3® (S7M120) 300 SQFT

Fantastic customer service plus the install went better than expected. The price was competitive considering the quality of the product, which I consider a great value. Finally the installation instructions were well written which included a parts list of my whole Sta-Rite system.

Works as good as the higher price brand. Very satisfied.

Filters fit like a glove and came packaged nicely. Quality and craftsmanship seem comparable to the OEM filters. We'll see how they hold up over the next year or so. If anything changes when I clean them in 6 months, I will definitely be back to adjust my review accordingly.

Ok as replacement product not sure about quality though

It is not the same quality of the Pentair cartridge filter, but so far it is holding up to being cleaned more than a few times already. Thank you for the quick delivery and making a quality product.

I have run a swimming pool service for 23 years, and serviced thousands of pools. It was a great day when generic cartridge production began for the Sta-Rite system 3 models. I have now bought this specific brand 9 times and I can tell you they are just as good as the OEM filters. People complaining that their pool turned green three days after putting these filters in are full of it. That would only be caused by operator error. And having the physical dimensions off by a quarter of an inch is a ridiculous complaint. This isn't a space ship. Anyway, I require customers to replace this model of filter cartridge every four years. I clean them on a 6-month interval. With that maintenance schedule these filters do a great job.

Adorable and fast delivery, it was at least $100.00 less than what my pool guy quoted.

Perfect fit. Much cheaper compared to local pool supply store. Update: after almost a year of use, still going strong. Thoroughly cleaned after almost a year with power wash. !
