PureValue Retro Fit Kit

The PureValue Retro Fit Kit is a smart and affordable fix for your reverse osmosis (RO) system when the filters wear out. Instead of buying a whole new system, swap out the aging filter head and keep the tanks and faucet that still work like new. The new RO filter head snaps easily into place, pushing your water purification system back to its best performance.

Replacing just the filter head means less waste, more savings, and you keep the parts that you depend on. The kit works with both four-stage and five-stage PureValue models, and it fits standard 1/4" tubing as well as high-flow 3/8" tubing. Whatever your setup, there’s a retrofit version ready to match.

Key Benefits

Fast & Easy Installation

The kit is designed for you to install in minutes. Just unplug the old filter head and snap in the new one using the quick-connect fittings. No tools, no fuss.

All-in-One Filter Assembly

Each kit comes as a complete filter head assembly with all the necessary housings and filter stages. Tanks, faucets, and the installation kit are not included, which means you keep the components you already trust.

Cost-Effective System Renewal

When your reverse osmosis (RO) tank and faucet are still in great shape, why replace the whole system? Our retrofit kit lets you replace the filtration core and keep the savings in your pocket.

Four-Stage Retrofit Options

• PUREVALUE 4EZ50-RK—50 GPD, 4-stage filter assembly for standard 1/4" tubing.
• PUREVALUE 4EZ50-3/8-RK—50 GPD, 4-stage filter assembly for 3/8" tubing, delivering quicker flow to the faucet.

Both 4-stage systems use the classic filtration sequence—sediment filter, carbon block, reverse osmosis, and post-carbon polishing—to keep your water pure and great-tasting.

Five-Stage Retrofit Options

• PUREVALUE 5EZ50-RK—50 GPD, 5-stage filter assembly for standard 1/4" tubing.
• PUREVALUE 5EZ50-3/8-RK—50 GPD, 5-stage filter assembly for 3/8" tubing.

The 5-stage systems add an extra carbon block filter just before the RO membrane so you get even better removal of chemicals and smells, giving you the cleanest, freshest water possible.

Final Words

The PureValue Retro Fit Kit gives your RO system a new lease on life without the hassle of a full replacement. By reusing your current tank and faucet, you cut costs, minimize waste, and make the swap quick and straightforward. Select the four-stage or the five-stage version and you’ll get a sturdy, high-performance assembly designed for simplicity, reliability, and long-lasting service.

When the water coming out of your faucet has dipped in quality but the main components are still solid, a PureValue Retro Fit Kit is the wise upgrade that brings fresh, clean water back into your home without breaking the bank.
