Customer Reviews
Excellent filters so far. Order came earlier then promised with a handwritten thank you note.
Easy shopping experience and fast shipping. Recommend
Cartridges fit perfectly in my CP 420 filter. Appear to be good quality. Glad they only have 1 band, all of the bands on my old filters had broken and fallen off. Macke Pool was great, arrived when they said.
Was looking for this specific product and Macke came through with easy ordering and prompt shipping!
First of all, I would never use any filters besides Pleatco filters! Second off the Advanced Ultra series are a game changer! They keep my pool cleaner and they last so much longer than my other filters. I am very happy with my purchase!
