RO Filter & Membrane Replacement Service

An RO system is a sequence of consumables doing timed work: sediment and carbon prefilters guarding the membrane, the membrane doing the fine rejection, and a polish filter finishing taste. Replacement service swaps each on its own schedule and sanitizes the system while it is open.

Overdue prefilters pass chlorine through to a membrane that chlorine destroys — so a few skipped cartridge changes quietly consume the expensive part. Water still flows either way; only the pressure and the numbers reveal the difference, which is why the change interval matters more than the taste test.

With RO carrying the PFAS and chloramine story in this market, the install base keeps growing — and every unit deserves to keep meeting the number it was bought for. We put the intervals on our calendar so they stop depending on yours.
