Why this filter
Before you buy
One maintenance cartridge, not all the filters in your system. Use the label and system reminder to identify the stage you need.
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 G3P800: close the faucet and wait 30 seconds before removing the old membrane cartridge. Twist it counterclockwise to remove it and fit the new one clockwise. Hold the RO indicator for seven seconds to reset it, then open the faucet for a 30-minute flush. Follow the full G3P800 manual and check for leaks.
