Signature Waterway 50 Skim WY45 Aquatune/Magnum Replacement Cartridge - SG50
Manufactured from quality Cartridge Element Media and made in New Zealand by Magnum Filters for Aquatune, the Signature Waterway 50 Skim is made of continuous filaments and does not weave out. It is heavier and sturdier than other filters on the market, and provides superior filtration - capturing particles as fine as 10 microns. These filters are our most frequently sold filter and suit Spa Industries Spas (and others). They have a handle on the top and a coarse external 49mm thread at the base. We believe this is the best quality replacement filter cartridge on the market. Please check dimensions before ordering and call us for confirmation is you're still unsure.
