What is reverse osmosis?

Reverse osmosis is one of the most thorough ways to filter drinking water and is designed to remove contaminants that typical filters can leave behind, including microplastics, PFAS, lead, chlorine, fluoride, nitrates, and more. It works by pushing water through an extremely fine membrane, capturing these larger contaminant particles while water molecules are allowed to pass through. The result is cleaner, noticeably better-tasting water, and a little less to think about.

Crushed single-use plastic water bottles
Bottled water
Bottled water may taste clean, but it uses more than 5,000 plastic bottles per household each year*. One NIH-supported study found an average of about 240,000 plastic particles in a liter of bottled water.

Sans uses 4-stage reverse osmosis to remove up to 99.9% of microplastics, plus at least 98.6% of other contaminants like PFAS. The clean taste you want without extra contaminants or bottles to throw away.

UV-C purification

After the reverse osmosis membrane, UV-C light adds a final layer of purification right before the water is dispensed — an added step many RO systems don't include.

Real-time water quality results

A built-in TDS monitor shows your water quality in real time, so you can feel confident about what's in every glass.

Auto-fill glass pitcher

The glass pitcher fills itself, so fresh, purified water is always ready. Place it in the fridge or bring it straight to the table. No plastic tank or carafe.
