Blue Wave120-Square Feet Replacement Cartridge White

Could be better price

Does its job

We have an above ground salt pool and I absolutely LOVE these filters! We live in a hot, humid climate, so algae builds up quickly in the filter. I purchased 2 filters, so when one gets corroded with algae, I use the 2nd filter and allow the algae to dry on the first cartridge. Once it dries, the algae can be "dusted" right off and the filter is good as new! When the other filter corrodes, remove, switch and repeat.

Have two of these and change out every month or so. The can be cleaned easily to be used again and again.

I wanted a second cartridge, so we could keep our pool crystal clean. So, Ipurchased so many 120 sqft replacement cartridges and not a single one fit. Thank you Blue Wave for being perfect and sensibly priced!

we use this filter on our pups heated indoor pool. this filter is expensive but has held up well.we have 2 filters we swap out every 10 days. will buy again

5 minute change plus 5 minute wash and you are back in business. This filter does a bang up job with crystal clear water and I couldn't be happier that I switched from sand to this one.

Works very well
