Prefilter pack: the cartridge set only, without an RO membrane. Complete replacement packs use the Sediment + SMART Plus prefilter set.

• Complete replacement pack, 500 GPD: the 2 prefilters plus 2 x 2.5" x 21" RO membranes (CQE-RC-04084).

Complete replacement packs are one-time purchases. Replace prefilters typically every 12 to 24 months, about 18 months for most homes; once a year on chlorinated city water. Replace RO membranes every 2 to 3 years. Actual life depends on feed water quality, system configuration and usage.
