Crystal clear water brings back the holiday spirit: pool and water maintenance is a breeze with Bestway Lay-Z-Spa Xtras filters. With dimensions of 10.6 x 8.0 cm, the cartridge immediately fits all Lay Z-Spa models. The thin-layer structure does not allow even the smallest dirt particles to escape. Even better: you can adjust the water filtration directly from your spa's digital control panel. The more often you check and clean the filter, the less likely you are to need to replace it. Cleaning is done in four simple steps: remove the filter from the spa's water inlet, remove the filter, rinse with a garden hose and reinsert it - done! Is the water still not filtered properly? Fortunately, the filter comes in a convenient double pack, so you can swap it out for a new one in a flash.
