CHF-Compatible RO Membrane — 50 GPD

The stage that does the actual filtering.

Everything else in your system exists to protect this one cartridge. The reverse osmosis membrane is where dissolved solids are reduced — the things far too small for any cartridge filter to catch.

A 50 gallon per day element in the standard 1812 size, producing roughly 190 litres a day depending on your water pressure and temperature.

How you know it's time. The tank takes longer to refill. The water tastes different, or tastes like nothing at all. Your TDS reading has climbed since the system was new. Or it's simply been two years. A membrane doesn't fail suddenly — it declines quietly, and most people don't notice until they compare a fresh one.

Getting a full life out of it. Membrane life comes down almost entirely to what sits in front of it. Chlorine attacks the membrane film directly and sediment blinds the surface, so keeping the sediment and carbon stages on an annual schedule is the cheapest way to protect a component that costs several times more.
