For Your Home
You already filter your water. That was the right call, and it is only half the job: the same process that takes out what you do not want takes the minerals with it.
Waimin is a small unit that sits after your filter and puts those minerals back, every time you use the tap. You install it once and then stop thinking about it.

Deep filtration can leave water tasting flat, because the minerals that give it body come out with everything else. Waimin puts calcium, magnesium, potassium and sodium back.
It sits in the line rather than on the bench, so the water you cook with, fill bottles from and make coffee with is all the same water. Nothing to pour, measure or top up.
Waimin is not a filter and does not replace one. It goes after whatever system you already own and works with reverse osmosis, distilled, purified and filtered water.
A cartridge lasts roughly a year in a typical household. Changing it is a two-minute job with no tools, and there is nothing else to maintain in between.

Before You Ask
Waimin connects to standard 1/4" or 3/8" water lines with push-fit fittings, after your existing system. Most people install it themselves in well under an hour, and no part of your current setup has to change.
How It Works

Waimin works after filtration and connects to 1/4" or 3/8" tubing.

Your water flows through the Waimin unit, where the cartridge adds calcium, magnesium, sodium, and potassium, along with trace elements from Himalayan salt, back in.

Remineralized water comes out of your tap, ready to drink. No daily effort, just replace the cartridge when needed.
For Your Home
One unit, one cartridge a year, and every glass in the house comes out right.
