Cartridge Set (4PK) Replacement For Pentair® Clean & Clear® Plus 420 by Optimum Pool Technologies

My 1st purchasing filter cartridges on my own. I called to ensure I was purchasing the replacement. Friendly staff confirmed I choose the correct one for my filter. He took my credit card and three days later they showed up on my porch, not two days as promised. I still give them a 5 star rating and will purchase replacement from them when time comes around again.

New filters

This is the first set of replacement filters I've purchased. The inner diameter on each end was not as tight as the factory filters. They fit correctly in every other way. I'd buy again!

wrong part but great customer service

these guys were great, even though I ordered the wrong cartridge they were so nice, sent me a prepaid fed ex label, the best customer service!!
