  • Five-stage filtration kit restores RO performance

Five-stage replacement filter kit

This five-piece set replaces every cartridge in a standard five-stage reverse-osmosis system. It contains two 5-micron coconut-shell carbon blocks, one 5-micron polypropylene sediment filter, one 50 GPD membrane and one 10-inch granular activated carbon post-filter with 3/8-inch quick-connect fittings. The kit matches the Watts W-525 configuration and fits several other common RO models.

Twist-in cartridges with quick-connect post-filter

Each stage uses a standard twist-lock housing so no tools are required for the sediment, carbon block or membrane cartridges. The final polishing filter ships with 3/8-inch push-to-connect fittings that snap onto existing tubing. The most common issue is forgetting to flush the new carbon blocks until the water runs clear, which can leave fine particles in the first few litres.

50 GPD membrane rating decides daily output

The included thin-film composite membrane is rated at 50 gallons per day under standard test conditions. If your household uses significantly more purified water than that, the tank will refill slowly and you may notice reduced flow at the tap. Buyers who need higher daily production should choose a system designed for a larger membrane.

Questions about this item

How do I know the 50 GPD membrane is producing water at the right rate after installation?

Time the fill of a measured container; the membrane is rated for 50 gallons per day, so output should match that daily volume under normal pressure.

Which filters and membrane come in the 5-piece set and is anything else required?

The set includes two 5 micron coconut shell carbon block filters, one 5 micron polypropylene sediment filter, one 50 GPD RO membrane, and one 10 inch inline GAC post-filter with 3/8 inch quick-connect fittings; no extra parts are needed for a standard change-out.

My system is labeled W-525 — is this the correct 5-piece kit for it?

Yes, the kit is listed as compatible with the Watts W-525 and W525 model numbers, so it matches that system.
