4-pack Biofoam filter, inflatable Lay Z Spa cartridge 58323 filter We Bestway[C]-yux

Brand new and high quality\nColor: Blue\nQuantity: 4 pcs\nYou are looking at Z-type foam filters that are compatible with many models of inflatable hot tubs.\nPlease note that you will see many misshapen versions of these filters for approximately the same price as square or hexagonal ones. They have this shape because they are cheaply manufactured and obviously not as good as the round types which provide a more consistent surface. They are also unusually thick, which obviously restricts water flow and puts a lot of strain on your pump. Why put a thick hexagonal foam block in a housing designed for round filters?\nI used the original filters myself for about 12 months and noticed that they only lasted about a week. It was almost impossible to clean them. More importantly, they cost me a fortune.\nI decided to investigate a foam alternative and after about 6 months of trial and error, I settled on the filters you can see in this listing. I have been using them ever since without any problems at all.\nThese are much cheaper than the original filters, much more free-flowing, and I find that they filter much better.\nI have managed to source round filters instead of the cheaper misshapen ones sold elsewhere. These filter the water much better due to the consistent surface and have proven to fit better.\nThese filters require more attention and I recommend using bromine as this chemical is odorless, cheaper, better for your skin, and much more filter-friendly.\nIf you choose to use chlorine, I strongly recommend changing these filters weekly.\nPlease note that these filters will discolor with use. This is completely normal and nothing to worry about. Other sellers dye their foam green to hide this, but I believe in being completely transparent with my customers.
