Description

Clean & Clear Plus Cartridge Pool Filters have a corrosion-resistant, injection-molded, fiberglass-reinforced, polypropylene filter tank featuring superior strength and reliability. The cartridge assembly uses four, nonwoven, polyester cartridges. There is no need for backwashing. The Clean & Clear Plus filter’s design provides maximum filter surface area to capture more dirt and solids and stretch out time between cleanings. Plus, we use the most durable materials to extend cartridge life. The Clean & Clear Plus filter delivers commercial-grade performance that keeps pools clean and sparkling, day in and day out. Pentair Clean & Clear Plus Cartridge Filters have a large filter area for increased dirt capacity, and if the pressure gauge shows that the system is running at 10 PSI higher than its starting pressure, it is time for a cleaning. Be sure to consult a pool professional before performing maintenance or attempting pool filter cleaning on your own, or call a servicer outright if you're unsure of how to clean a pool filter. Large filter area for increased dirt capacity

Buy these (OEM) because they last much longer
My last OEM’s lasted 6 years with semi-annual cleanings. My pool guy tells me you’re lucky to get half that with the 3rd party alternatives. So very much worth the extra cost.

NOT GENUINE OEM PARTS
Wording of the ad led me to believe it was a true Pentair product. It’s is not, even though it showed up in Pentair packaging. The picture in the ad even shows Pentair filters. These are not. They don’t even fit tightly and would allow particles to bypass the filter media. Believe the other one star reviews. If you think you are getting OEM parts, you are not. ... show more

True Pentair Brand pool cartridges! Great value!
This seller and product is 100% Quality Brand Pentair replacement (4) pool filter cartridge set! Looked everywhere for Pentair real cartridges for our inground Pentair pool filter. Finally found this seller who assured me I would not recieve replica/fake cartridges. That they only sold brand name Pentair cartridges. Great value compared to other sellers. Super fast shipping. I could not be happier with the customer service I received. Beyond happy as a single mom with these cartridges and how they performed all summer to keep my kids inground pool sparkling clean! These quality cartridges will keep our pool clean for years. ... show more
