Where to Get Distilled Water—and When to Make Your Own

Updated September 29, 2026

If you need to know where to get distilled water, the fastest dependable option is usually a nearby grocery store, pharmacy, medical-supply retailer, or water-delivery service. Availability changes quickly during storms and shortages, so call ahead and confirm that the label says distilled rather than purified, spring, drinking, or demineralized water.

Common local sources

• Grocery and big-box stores, usually in the bottled-water or infant-care aisle
• Pharmacies and medical-supply stores, often for humidifiers or CPAP equipment
• Water-delivery companies and commercial beverage suppliers
• Laboratory or industrial suppliers when a documented grade is required
• Marine or automotive retailers for equipment uses—not automatically for drinking

Read the intended-use label. Water sold for batteries, radiators, laboratories, or industrial processes may not be packaged or certified as drinking water. For medical devices, use the water type and cleaning procedure specified by the device manufacturer.

Distilled is not the same as sterile

Distillation boils water and condenses the vapor, separating many dissolved solids and microbes from the collected water. The final product can be contaminated again by dirty tubing, hands, or storage containers. Ordinary distillation may also be less effective for some volatile chemicals unless the system includes suitable pretreatment or venting.

The EPA’s guide to selecting water-treatment systems summarizes the benefits and limitations of distillation and other treatment methods.

Making distilled water at home

Small-batch stovetop methods can demonstrate the process but are slow, fuel-intensive, and easy to contaminate. A purpose-built unit is more practical when repeated production is required. The active Gravi-Stil survival water distiller is designed to distill challenging feed water, including brackish or salt water, when operated according to its instructions.

Confirm the unit’s batch output, fuel needs, cooling-water requirements, setup, cleaning, and safe operating location. Hot metal, steam, pressure, and flame can cause serious injury. Never seal a boiling system or alter its relief and venting path.

What changed from the previous article

The AquaViable AV-5 atmospheric water generator and the Crystal Quest portable RO unit previously promoted here are not currently active products in the store. They have been removed rather than replaced with equipment that solves a different problem.

When you need drinking water—not necessarily distilled water

Distilled water is not required for most emergency drinking situations. The priority is water that is microbiologically and chemically safe for the source and intended use. During a local emergency, follow instructions from the water utility or public-health authority. Boiling can address many microbial hazards but does not remove salts, fuels, heavy metals, or many chemicals.

For stored emergency drinking water, the active Ready H2O pallet is a bulk option to evaluate. Check packaging, storage temperature, lot dates, space, rotation, and delivered quantity before ordering.

Store distilled water correctly

• Use clean, food-grade containers for water intended for consumption.
• Keep containers tightly closed and away from fuels, pesticides, and solvents.
• Store in a cool, dark place protected from freezing and excessive heat.
• Label the source and date.
• Avoid touching the inside of caps, spouts, and containers.

Build redundancy

Keep several water strategies: a stored drinking-water reserve, a way to treat local fresh water, and distillation only where its broader contaminant removal or specialized use justifies the energy. Knowing where to get distilled water is useful; knowing why you need it prevents buying the wrong product during a shortage.
