A standard size replacement membrane is much less expensive and so much easier to replace. We suggest using the standard size Dow Filmtec 100 GPD membrane, RO membrane housing and 1000 ml inline flow restrictor. Ordering the RainSoft TRS2514-150 here will be fulfilled with the Dow Filmtec 100 GPD membrane, Membrane housing and matching flow retrictor. Learn More
