The Water Trinity

Filter.
Bathe.
Drink.

Water reaches you three ways: the tap, the tub and the glass. Get all three right, in that order. It starts with knowing what's in it.

// order in four steps

Test it. Then filter, bathe, drink.

Start with a home test. Then the Water Trinity: one for your house, one for your bath, one for your kitchen.

  1. 1Test your water

  2. 2For your house

    The Perfect FilterWhole-house, installed by local dealers

    Filters the water where it enters your home, so every tap, shower and tub gets it. A filter only removes what it's certified to remove, so ask for the certificate.

// step zero · test your own tap

EPA records describe your water system. A home test tells you what’s in your water at your tap. It doesn’t diagnose anything.

The same water feeds your kitchen tap, your shower and your tub.
So the fix covers all three.

// the trinity

Three things. One water.

Once you know what's in your water, this is the order we'd do it in: clean up the supply first, then the bath, then the glass.

01

Filter

A whole-house system at your main line, so every tap and shower draws from filtered water.

Step 01 →
02

Bathe

A hydrogen bath machine for the tub. A spa soak, built on the filtered water from step one.

Step 02 →
03

Drink

A hydrogen unit under the kitchen sink that runs on the filtered water from step one. Or start small with a bottle.

Step 03 →
// step 01 · filter

Filter the whole house.

Everything that follows is only as good as the water you put into it. A whole-house system treats water where it enters your home, so the kitchen tap, the shower and the tub all draw from the same filtered line. Filter first. Then everything else.

Ask before you buyA filter only removes what it has been tested and certified to remove. Bring your report and ask any dealer which NSF/ANSI certification covers the contaminants on it.

Whole-house · our main pickLocal install

The Perfect Filter

A whole-house filtration system installed at your main water line, sold and set up through local Perfect Filter dealers.

// step 02 · bathe

Then, soak in it.

With filtered water filling the tub, a hydrogen bath machine infuses that bath water with molecular hydrogen gas. Think of it as a spa soak: time to relax, at home.

Hydrogen, honestlyMolecular hydrogen is under study; results vary; not a medical treatment. Research on hydrogen baths is early, and we won't tell you a bath treats anything.

// step 03 · drink

Last, drink it.

The final piece is the glass. Our pick for the kitchen, Echo Flow, has no filter of its own. It's built to run on water you've already filtered, which is exactly why the Trinity starts with step 01.

Hydrogen, honestlyMolecular hydrogen is under study; results vary; not a medical treatment. And just because water is alkaline doesn't mean it has hydrogen in it. Those are two different things.

We may add another drinking option later. These are our picks today.

Under the sink · our main pickEcho

Echo Flow Hydrogen Water Machine

A hydrogen machine that fits under your kitchen sink. Echo says it has no filter of its own and connects to the filtration you already have, at the faucet, the fridge or the ice maker. Pair it with a whole-house filter from step 01.

Echo Ultimate

Echo says it makes hydrogen, alkaline, acidic and 5-stage filtered water from one kitchen tap. A good fit if you want the filtering and the hydrogen in a single machine.

// our promise

The fine print, up front.

01

We earn commissions, and say so

Links marked as affiliate links pay us if you buy. You pay the same price either way, and a commission never decides what goes on this page.

02

No prices on this page

Prices and sales change. Every product link goes to the maker's own page, so the price you see there is the current one.

03

Hydrogen, honestly

Molecular hydrogen is under study; results vary; not a medical treatment. Nothing here is medical advice. Talk to your doctor about your health.

04

Certified claims only

A filter only removes what it's certified to remove. If a maker's claim isn't backed by a certificate, we won't repeat it as fact.
