Just buy the filter you won't regret it!
[This review was collected as part of a promotion.] Oh man this baby is heavenly with this amazing filtration system, durability with all the dirty that gets in from dirty kids feet. I love how compact and tight the filter is and easy to replace and maintain. I received this complementary from Influenster to give my completed on his opinion, but I have a big one . 😂
Very stong not flimsy.
[This review was collected as part of a promotion.] This new pool filter is super stridy and really durable upon looking at it as i took it out of the box. The size is perfect. The filter is the white part which it super stong. Its better than the last one i have.
Super efficient!!
[This review was collected as part of a promotion.] I was so impressed when I pulled this filter out of the box! It is so well-made and has so many folds to trap all of the little spring flowers coming off of the trees in our backyard. It is amazing and works much better than the filter that we originally had!! I would recommend purchasing this replacement filter!!
