This is the genuine Davey replacement filter cartridge (part Q2312) for the Davey CrystalClear 39100EU pool and spa cartridge filter. The polyester element sits at the heart of the filtration system, trapping suspended particles as water passes through so that clean, clear water is returned to the pool. It is designed to be periodically removed, cleaned, and reused, with full replacement recommended approximately every two seasons depending on usage and cleaning frequency.<\/p>\n
This cartridge is the correct OEM replacement element for the Davey CrystalClear 39100EU cartridge filter \u2014 a model suited to small and medium-sized in-ground and above-ground swimming pools and spa pools. The 39100EU is the European-market variant of the 39100 series and features unions sized for 50 mm European PVC pipe. Always verify your filter model number before ordering; other CrystalClear models in the range use different cartridge references (e.g. Q2311, Q2313).<\/p>\n
Pool water enters the filter tank and passes through the pleated polyester cartridge element, which captures dirt, debris, pollen, and other fine particles. As the element loads up, pressure rises and flow to the pool decreases \u2014 the signal to remove and clean the cartridge by spray-washing. When cleaning no longer restores adequate flow, or after approximately two seasons of use, the cartridge should be replaced with a fresh genuine Q2312 element to maintain optimal filtration performance.<\/p>\n
As a genuine Davey part, the Q2312 cartridge is engineered to the exact dimensions and material specification of the original element, ensuring a precise fit inside the 39100EU tank and consistent filtration performance. Using the correct OEM cartridge protects your filter housing, maintains the manufacturer’s intended flow rates, and avoids the risk of poor sealing or premature failure associated with ill-fitting aftermarket alternatives.<\/p>","protected":false},"excerpt":{"rendered":"
