Joseph’s Well is a DIY guide that promises to show you how to build a small machine that pulls drinking water out of the air. The sales video leans hard on a “40 gallons a day” headline and a faith-based preparedness story. So what do you actually get, does the idea work, and who should (and shouldn’t) buy it? We went through the official sales material, the vendor’s own FAQ and terms, and the science behind atmospheric water generators to give you a straight answer.
Quick verdict
Joseph’s Well is a reasonable, low-cost DIY project guide for people in humid climates who like building things and want a backup water source. It is not a magic water machine. The realistic output is far below the 40-gallon headline, it depends heavily on humidity, and the water must be filtered before drinking. If you go in with those expectations — and you are protected by the refund window — it can be a worthwhile weekend project.
- Best for: preppers and DIYers in humid regions who want a supplemental water source
- Not for: people in dry climates, or anyone who wants a plug-and-play device
- Format: digital guide (video, blueprints, materials list) — a printed edition is also offered
What is Joseph’s Well?
Joseph’s Well is an information product, not a finished appliance. You get instructions for building your own atmospheric water generator (AWG) — a device that cools air below its dew point so that the moisture in it condenses into liquid water, the same principle a household dehumidifier uses.
The program is presented by “John Gilmore.” According to the product’s own terms and disclaimer, that name is a pseudonym used for storytelling and privacy. The guide is sold through Digistore24 (and other retail platforms), and the name is a reference to the biblical story of Joseph storing provisions ahead of a drought — the whole presentation has a Christian preparedness tone.
What’s included
Based on the vendor’s sales material and third-party summaries, the package includes:
- A step-by-step video build guide, from sourcing parts to final assembly
- Printable blueprints and diagrams
- A materials list with notes on where to buy parts
- Two power options: standard grid power and a solar setup for off-grid use
- Email support from the vendor
- Bonus guides on storing a household water reserve, purifying and mineralizing water, and understanding what’s in tap water
The vendor says the core parts cost under $150 at a hardware store (solar components not included). That figure may assume you can reuse some parts, so budget a bit more to be safe.
Does it really make 40 gallons a day?
This is the most important question, and the honest answer is: probably not, and the vendor’s own materials don’t agree with each other.
- The sales page headline says 40 gallons a day.
- The product FAQ, as quoted in independent coverage, says the DIY build produces up to 10 gallons a day under favorable humidity and temperature.
- Higher figures mentioned in the video refer to large commercial-style systems, not the home build.
Treat 10 gallons a day as a best-case ceiling, not a typical result. Real output depends on relative humidity, air temperature, airflow, the quality of your build and how much electricity you are willing to use. In dry air — roughly below 40% relative humidity — output drops sharply, and in desert climates a small condensation unit may produce very little.
How atmospheric water generators work (and their limits)
Air always contains some water vapor. An AWG blows air over a cold surface; when that surface is colder than the dew point, vapor condenses into droplets that are collected in a tank. The physics is well established — but it comes with trade-offs:
- Humidity is everything. Warm, humid air holds much more water than cool, dry air.
- It uses energy. Cooling air takes power. The guide’s parts estimate does not include your electricity cost, and a solar setup adds expense.
- The water needs treatment. Condensed water can pick up dust, microbes and residue from the equipment. Always filter and disinfect it before drinking. A homemade unit is not certified by the EPA, NSF or any similar body.
- Maintenance matters. Coils, collection tanks and filters must be cleaned regularly to prevent mold and bacteria.
Pros and cons
Pros
- Low entry cost compared with commercial AWG units, which typically cost hundreds to thousands of dollars
- Based on a real, proven principle (condensation)
- Grid and solar options for off-grid or emergency use
- Useful bonus material on water storage and purification
- Refund window offered through the retailer (see below)
Cons
- Inconsistent output claims (40 vs. 10 gallons per day)
- Results depend heavily on your climate
- Requires hands-on assembly and basic tool skills
- Ongoing electricity and filter costs
- Author uses a pseudonym and testimonials are not independently verified
- Strong religious framing that won’t appeal to every reader
Price and refund policy
Joseph’s Well is a one-time purchase. Pricing is promotional and changes over time, so always confirm the current price on the official order page before you buy. The vendor advertises a 60-day money-back guarantee; because the terms say each product specifies its own refund policy, check the refund terms shown at checkout. Orders through Digistore24 are processed by Digistore24 as the retailer.
| Product type | Digital DIY guide (printed edition available) |
| Build cost (vendor estimate) | Under $150 in parts, excluding solar |
| Realistic output | Up to ~10 gallons/day in favorable conditions; much less in dry air |
| Refund | Advertised 60-day guarantee — confirm at checkout |
| Skill level | Beginner to intermediate DIY |
Who should buy Joseph’s Well?
It’s a good fit if you live somewhere humid (coastal areas, the Southeast US, tropical regions), enjoy DIY projects, and want a backup water source as part of a broader emergency plan.
Skip it if you live in a dry climate, need a reliable primary water supply, or want something that works out of the box. In those cases, a certified commercial water filter, stored water, or rainwater harvesting (where legal) will serve you better.
Alternatives to consider
- Stored water: Ready.gov (FEMA) recommends storing at least one gallon of water per person per day for at least three days. It’s the simplest and most reliable emergency step.
- Rainwater harvesting: high yield in rainy regions; check your state’s rules first.
- Commercial AWG units: more expensive, but tested and ready to use.
- Portable filters: essential if you have access to any natural water source.
Frequently asked questions
Is Joseph’s Well a scam?
It is a real product that you receive after purchase, and it is sold through established retail platforms with a refund policy. The main problem is marketing: the 40-gallon headline overstates what the vendor’s own FAQ says the build can do.
Is the water safe to drink?
Not straight from the machine. Condensed water should be filtered and disinfected, and the unit must be kept clean. A homemade device is not certified for drinking water safety.
Does it work in dry climates?
Poorly. Below roughly 40% relative humidity, output drops dramatically.
Do I get a physical machine?
No. You get instructions and plans; you build the unit yourself.
Final verdict
Joseph’s Well is best understood as an affordable DIY plan for a supplemental water source — not a solution to every water problem. If you live in a humid area, like hands-on projects and keep realistic expectations, it’s an inexpensive way to add another layer to your preparedness plan, backed by a refund window. If you need guaranteed, high-volume drinking water, look elsewhere.
