San Francisco, California

Reverse osmosis filtered drinking water for San Francisco homes.

We specialize in under-sink reverse osmosis filtration systems for the water you drink and cook with. We help you choose a system, deliver it, and provide guidance for installation by an independent licensed plumber you choose and hire directly. Whole-home filtration is also available by request.

Why consider under-sink filtration?

Enjoy fresh-tasting water for drinking, coffee, and cooking in your San Francisco home, with less reliance on bottled water and no cases to carry or store. An under-sink RO system filters water right where you use it, making it a practical option for city houses, condos, and apartments.

Your taste preferences

We'll discuss your specific water filtration needs and how filtration may fit your preferences. We explain the selected system's capabilities.

The bottled water habit

A dedicated drinking-water faucet can reduce your reliance on bottled water, saving you money and tons of wasted plastic over time.

Older-plumbing concerns

Plumbing materials can influence water at the tap. If you have concerns, we can discuss equipment capabilities and point you toward SFPUC testing information.
