Reverse Osmosis Replacement Filters

Match Reverse Osmosis replacements to your exact system and service stage. ROCOMP, ROUSA, countertop and other multi-stage RO systems do not all use the same cartridges.

Filters and membranes have different jobs

Pre-filters, membranes and finishing cartridges can have different maintenance requirements. Follow your model’s service schedule and check what is included in a replacement pack before ordering. Do not infer membrane replacement from a pack’s title alone.

If your compact RO depends on Whole House pre-filtration, maintain that system too. Use the service guides or send AquaCo the model number and a photo for a compatibility check.

Choosing a new system? Compare Reverse Osmosis systems and read our fluoride-reduction guide.
