Product overview

Waterdrop G5P500A in practice.

A compact 500 GPD RO system with mineralization and a simple mechanical faucet.

For a water filter, the treatment technology, verified reduction claims, flow, replacement-filter cost and match to your water matter more than the number of “stages.” A reverse osmosis system also depends on membrane condition, pressure and regular service.

The faucet does not display TDS; use testing rather than the faucet to assess water. Read the water filtration FAQ, check public water data, or compare all RO systems and filters.
