The Hydration Stack
Your one-stop shop for ending bottled water and delivery for good. This bundle brings together a highly certified reverse osmosis system, Okinawan coral that replenishes calcium, magnesium and over 70 trace ocean minerals, and a vortexing step that brings natural movement back to your water.
Named “Best Upgrade Reverse Osmosis Water System” by Forbes Vetted (2026)
Will it fit under my sink?
Farm sinks and tight cabinets usually work: the cartridges can mount to the side of the cabinet and the tank can lie on its side. Not sure? Send a photo to hello@thegoodforco.com and we will confirm the fit before you order.
Certifications
Certifications are for the GoodFor 8500, tested by the Water Quality Association. The UMH Pure is TÜV EU certified.

What's in the box
Upkeep and warranty
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.
Purify. Replenish. Structure.

And by design
Reverse osmosis also reduces sodium, nitrates and nitrites, chloramine byproducts, dirt, rust and sediment, and typically 97.5% or more of total dissolved solids.
Certified figures are the WQA-tested reductions for the GoodFor 8500, NSF/ANSI 42, 53, 58, 401 and 372; a check means certified without a published figure. Arsenic figures apply with detectable free chlorine at the inlet.

The Sango Coral
Beautiful, sustainably harvested Okinawan coral adds natural electrolytes back to your water: calcium, magnesium, sodium and potassium, with over 70 trace ocean minerals. All from one natural source, not manufactured mineral balls, and no packets to mix. About two years a cartridge.
The minerals it puts back
The four core electrolytes
Calcium and magnesium lead, in their natural 2:1 balance, with sodium and potassium alongside.
Over 70 trace ocean minerals, including
Where the minerals come from
340 g of food-grade Sango coral per cartridge. Nothing synthetic, nothing added.
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
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
Installs last in the line, after the Sango Coral, with quick-connect fittings. No soldering, no electricity.
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.
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.
Free shipping · 30-day returns on unused items · 10-year warranty on the GoodFor 8500
