The Spout Monolith
Clean drinking water at home — without relying on tap, bottles, or delivery. Up to 2.5 gallons of alkaline water a day, made from the air.
Best for: Design-conscious homes wanting plastic-free, off-grid drinking water
Everything the Monolith does
One countertop unit: water generator, six-stage purifier, remineralizer, and home air purifier.
Water from air, no plumbing
Pulls moisture straight from the room and turns it into clean, alkaline drinking water. No pipes, no installation — just a standard outlet.
Exceptionally pure
Six stages of filtration remove PFAS, lead, chlorine, and microplastics, then add back essential minerals like calcium, magnesium, and potassium.
Air purification built in
Dual-layer MERV 13 air filtration removes dust, odors, smoke, and VOCs — refreshing your home's air while it makes your water.
Smart pitcher stays fresh
The Always Fresh Pitcher's UV-C light keeps water clean for days, and level sensors stop the flow automatically when it's full.
Fridge-ready, easy to clean
The slim half-gallon pitcher slides into a fridge shelf or door. The base is dishwasher-safe and the smart lid wipes clean.
Solar-ready & portable
At 25 lbs with no plumbing, it moves anywhere — and runs off-grid on a ~2 kW solar array.
Modern water isn't safe by default
Aging pipes, industrial chemicals, and plastic pollution have made clean drinking water harder to count on — and bottled water brings its own risks.
PFAS
Detected in nearly half of US tap water. These man-made chemicals don't break down and build up in the body, with links to cancer, thyroid disease, and immune harm.
Microplastics
Bottled water can carry hundreds of thousands of plastic particles per liter. They've been found in human blood and organs, where they can trigger inflammation.
Lead & heavy metals
Millions of homes still have lead service lines. Even low levels are tied to developmental problems in children and cardiovascular issues in adults.
Chlorine byproducts
Chlorine kills bacteria but forms disinfection byproducts (THMs) that have been linked to bladder cancer and reproductive concerns.
How the Spout makes water from air
The Monolith mirrors the natural water cycle — condensing moisture, filtering it through six stages, and remineralizing it for a clean, balanced taste.
Pulls moisture from the air
A NASA-inspired ceramic system quietly captures water vapor from the surrounding air — anywhere with at least 20% humidity.
Purifies and sterilizes
The vapor is condensed into liquid (distilled inside the machine first) and sterilized with UV-C light to kill bacteria and viruses.
Filters and mineralizes
Water passes through the NASA-derived filter, then is enriched with calcium, magnesium, and potassium for a smooth alkaline taste.
Dispenses to the smart pitcher
Fresh, mineral-rich alkaline water flows into the Always Fresh Pitcher — ready to pour, chill, or refill up to 5 times a day.
*Depending on local kWh pricing and conditions. Spout estimates savings up to $4,000/year for the average household.

Born from a drought notice
Spout began when founder Reuben Vollmer's parents — recently retired to a small California mountain ranch — received a state notice that they could lose their water rights during the drought. Walking his dog the next morning, he looked at the dew on a lawn and asked: why couldn't the moisture in the air be a water supply?
He spent the next decade engineering atmospheric water harvesting systems, visiting Flint, Michigan early on to hear directly from families affected by the contaminated-water crisis. Those stories shaped the company's mission: clean, abundant water that anyone can trust, anywhere — no pipes required.
After years of prototypes and refinement, the result is the Monolith: a NASA-inspired countertop water harvester that mirrors the natural water cycle, won an iF Design Award, and has been covered by Fast Company, Dezeen, and more.
Spout Monolith FAQ
Every common question, answered. Anything else — email us and we'll get you an answer fast.
How much water does the Spout make per day?+
Between 2 and 2.5 gallons per day in typical conditions, depending on temperature and humidity. Output ranges from 0.75 gallons in very dry conditions up to 2.5 gallons when humidity is high.
Will Spout work where I live?+
Spout works in any climate with at least 20% humidity — that's just about everywhere in the United States and over 80% of the rest of the world.
What is the power usage?+
Roughly 380–600 watts depending on conditions (rated range 360–640 W). It plugs into any standard wall outlet — no special wiring.
Can it run on solar?+
Yes. Spout recommends at least a 2 kW solar array, which is roughly a 6 ft × 4 ft panel footprint. That makes it a genuine off-grid drinking water option.
How often do the filters need changing?+
The Monolith uses one water filter and one air filter, and both should be replaced every 3 months for peak performance. The filter subscription delivers 2 complete packs (2 air + 2 water filters) every 6 months for $99, so your next set arrives before you run out. See our Spout Filter Pack listing on the accessories page for full details.
Can I use other brands of filters?+
No — only genuine Spout filters fit the machine properly. The good news: used filters can be mailed back to Spout for free recycling.
How pure is the water?+
Every drop passes through six stages of filtration, and the water is distilled inside the machine before filtering. Per Spout's published third-party lab results (National Testing Laboratories), no detectable PFAS, microplastics, or lead were found in Spout water.
What is alkaline water, and why does it matter?+
Alkaline water has a higher pH than standard tap or bottled water, which may help reduce acidity in the body. Spout enriches its water with calcium, magnesium, and potassium for a smooth, clean taste with no plastic, chlorine, or metallic aftertaste.
Is the water safe to cook with?+
Yes — it's excellent for cooking as well as drinking, and many owners feel it improves the flavor of their dishes.
Will it dry out the air in my home?+
No. While Spout harvests humidity from the air, the change is not typically noticeable in an average home.
We cook strong-smelling foods — will the water pick up odors?+
Spout's air filter is designed to reduce odors and airborne particles before the water is made. For best results, place the unit in a ventilated space and replace filters on schedule.
How do I remove and clean the pitcher?+
Lift the cylinder above the pitcher up an inch or two, tilt the top of the pitcher toward you, and it comes out. Clean the inside gently and rinse thoroughly. When replacing it, push down firmly so the orange ring at the bottom lifts visibly. The base is dishwasher-safe and the smart lid wipes clean.
Should I turn it off when traveling?+
The Spout automatically stops once the pitcher is full, but as a general rule it's recommended to turn it off when leaving town — like any appliance.
What's included in the box?+
The Spout Monolith unit, the Always Fresh Pitcher, one air filter, one water filter (your first 3 months), a water-resistant travel carry bag, the quickstart guide and user manual, and a 1-year limited warranty.
What are the price and shipping details?+
Pricing runs $1,495 (reserve; ships September 2026) to $1,995 (in stock, free shipping), with financing available from about $94/month. Every unit carries a 30-day money-back guarantee and a 1-year limited warranty. Note: no shipping to PO boxes. Email us for current pricing and availability.

Our hands-on review
Spout makes the atmospheric-water category aspirational: the Monolith pulls humidity from the air, condenses it, then runs it through a multi-stage air and water filter with UV-C sterilization to deliver clean, alkaline drinking water — in a countertop unit that looks like design furniture rather than an appliance.
Spout now publishes lab results showing non-detect levels of PFAS, lead, and microplastics, and the system remineralizes the water with calcium and magnesium so it tastes clean rather than flat. A built-in dual-layer filter means it doubles as an air purifier, clearing dust, odors, and VOCs while it works. The companion Always Fresh Pitcher uses UV-C and sensors to keep half a gallon ready and fridge-cold, and the base is dishwasher-safe.
Output runs 0.75 to 2.5 gallons a day depending on humidity (it keeps working from about 20% RH up), drawing 360–640 watts at roughly 5–9 kWh per gallon, and it's even solar-ready for off-grid setups. Pricing is $1,495 to reserve a unit (ships September 2026, saving $500) or $1,995 in stock with free shipping, plus Affirm financing from about $70/month and a 30-day money-back guarantee.
What we love
- Third-party lab non-detect for PFAS, lead, and microplastics (per Spout/NTL)
- Makes clean, alkaline drinking water with no plumbing
- Doubles as a home air purifier (removes dust, odors, VOCs)
- Smart Always Fresh Pitcher with UV-C stays fresh for days, fridge-ready

The HU Recommendation
Our featured pick for design-forward atmospheric water, and a natural fit for HU readers exploring off-grid and resilient water. Spout's published third-party lab results (National Testing Laboratories) show non-detect for PFAS, lead, and microplastics; combined with remineralization and built-in air purification, it stands out. Confirm your local average humidity before buying; in very arid regions, also look at the Vapor Originators category. Prices change often — verify the latest on WaterVO's Spout listing.
