Before you buy

Choose this supply only when you need the CF or CB stages. The extra CF cartridge is a spare for a later change, not another stage to install now. If your RO membrane is due, it must be purchased separately. The package name does not guarantee a year of use.

Why this filter

What’s included

Includes two CF pre-sediment/carbon cartridges and one CB final-carbon cartridge. No RO membrane or separate mineral cartridge is included.

How this compares

This is a checked replacement, not a Best Overall or Best Value winner yet. Before choosing a winner, we need other filters we can trust, a fair comparison of how they work and how reliable they are, and current prices including shipping.

Filtration tests and details

These records explain which filter results we have checked and what their limits are. The same certification name does not mean two filters work equally well.

What we have verified about filtration

We have not yet verified the exact model's health-related contaminant reductions against a current independent certification listing. Manufacturer claims alone do not establish that this filters better than another option.

Installation and care

Installing the replacement

For G3P600 only: close the faucet and wait 30 seconds before changing a cartridge. Remove its wrap and cap, match the correct CF or CB position, and twist clockwise into place. Hold the matching indicator for seven seconds to reset the stage you changed. CF flushes automatically for five minutes with the faucet closed; CB needs a 15-minute flush with the faucet open. Follow the full manual and check for leaks. Keep the spare CF cartridge for a later change.
