Under-Sink Reverse Osmosis System

A 5-stage under-sink system for households that want to stop buying bottled water. It installs out of sight and runs to its own dedicated faucet.

How it works

Water passes through sediment and carbon pre-filters, then a reverse-osmosis membrane whose pores are fine enough to hold back dissolved solids, followed by a polishing carbon stage. The RO membrane is what reduces lead, fluoride, chlorine, nitrates and many PFAS down to trace levels, so what reaches the faucet is close to pure.

Good to know

• Reduces up to ~99% of total dissolved solids, including lead, fluoride and chlorine
• Dedicated brushed-steel faucet keeps filtered water separate from the tap
• Fits under a standard kitchen sink; quick-connect fittings, no soldering
• Replaceable pre-filters and membrane; a TDS check tells you when to swap
