Why families switch

Better than bottled. And it never runs out.

No factory, no bottling line, no plastic bottle to shed microplastics into your water. It goes from your kitchen faucet straight to your glass: purified, with the minerals put back.

No cases to carry, no jugs to fill, no delivery days and no running out on a Sunday. Water this good for every glass, every pot of pasta and every ice tray.

The Sango Coral

The UMH Pure water structuring device
03 · Structure

The UMH Pure

A solid quartz crystal pyramid and seven glass vials send your water spiraling in a double helix, bringing back the natural movement of a mountain stream, for a smoother, more satisfying feel. Made in Austria. No power, nothing to replace.

How the UMH Pure works
What's inside
1Solid quartz crystal pyramid
7Handcrafted glass vials

How it moves your water

Inside the gold-plated chamber, the quartz crystal pyramid splits the stream and sends it spiraling in a double helix past seven sealed borosilicate glass vials. It is the folding, turning motion water has in a mountain stream, instead of being pushed in a straight line through miles of pipe.

Good to know
Made in AustriaAdds nothing to your waterTakes nothing outTÜV EU certified5-year warranty

Installs last in the line, after the Sango Coral, with quick-connect fittings. No soldering, no electricity.

What it costs to own
$2.74a day

for a family of four, over the first two years.

Less than one bottle of spring water a day, for the whole family.

Spread over its first two years, the Stack costs your household less each day than a single bottle of spring water. After that, replacement cartridges come to under $1 a day.

Installation takes about an hour, and we provide concierge-level support for you or your plumber.

Before you buy

The questions people ask right before they buy.

Doesn't reverse osmosis take the minerals out too?

Yes, every reverse osmosis system does, ours included. That is exactly why the Sango Coral is in the Stack: calcium, magnesium, sodium and potassium go back in, with over 70 trace ocean minerals, from fossilized coral. Nothing synthetic.

Isn't this an expensive alkaline filter?

No. An alkaline cartridge is filled with manufactured mineral balls and gets replaced every 6 to 12 months. The Stack is three products, each doing one job: a reverse osmosis system with five NSF/ANSI certifications, coral that puts natural minerals back for two years at a time, and a structuring device that never needs replacing.

I already have an RO. Do I need the whole Stack?

No. Add the GoodFor Sango Coral, or the Sango Coral and the UMH Pure, to the system you have.

Should I wait for a tankless version?

A tankless unit needs a plug. Lose power in a storm and you lose your drinking water, which is when you want it most. The Stack runs on water pressure alone.

Is the faucet in the photos the one I get?

Yes, in chrome, brushed nickel or matte black. If you would rather not add a second faucet to your counter, add the 2-in-1 kitchen faucet above the Add to cart button: it replaces your main faucet and pours both.

Can I return it?

Unused, in original packaging, within 30 days.

One of the best upgrades a healthy home can make.

Purified, replenished with natural electrolytes and structured, straight from your kitchen faucet. For every glass your family pours, every day, without another bottle or delivery.
