Las Vegas' most affordable purified water. Family-owned and operated since 2003, delivering crystal-clear reverse osmosis water at a price that makes sense for your family.

The Process

What Is Reverse Osmosis Water?

Reverse osmosis is a multi-stage filtration process that forces water through a semi-permeable membrane under pressure. This is designed to reduce dissolved contaminants, including chlorine, fluoride, lead, nitrates, arsenic, and other impurities commonly found in municipal tap water.

Las Vegas tap water is notoriously hard and heavily treated. It travels long distances through aging infrastructure and arrives at your tap loaded with calcium carbonate, chlorine, and byproducts of the treatment process. RO filtration is designed to significantly reduce these substances.

The result is water with a neutral pH of around 7, clean, clear, and free of the off-flavors that make Las Vegas tap water so unpleasant to drink or cook with. It's also safe for sensitive applications like CPAP machines, baby formula, humidifiers, and aquariums.

At $0.40 per gallon, our purified RO water is a fraction of the cost of bottled water, and noticeably cleaner tasting than local tap water. Bring your own container, or pick one up in store.

Conveniently located at 9132 W Sahara Ave near the Durango and Sahara intersection — serving customers from Summerlin, Spring Valley, Rhodes Ranch, The Lakes, Peccole Ranch, and the greater west Las Vegas area.

Why Customers Choose RO Water

Uses & Benefits of Purified Water

Drinking & Daily Hydration

A clean, neutral-tasting option for everyday drinking water. Free from the chloramine taste common in local tap water — many customers notice the difference immediately.

Cooking & Soups

RO water lets the true flavors of your food shine. Eliminating mineral interference produces noticeably better-tasting soups, pasta, rice, and coffee.

CPAP Machines

The recommended water type for CPAP humidifier chambers. Prevents mineral buildup that degrades machine performance and shortens equipment life.

Humidifiers & Steamers

Mineral-free water extends the life of humidifiers and steam appliances by preventing the white dust and scale deposits that tap water leaves behind.

Baby Formula

Low-mineral purified water is widely used for mixing infant formula. RO water has a lower mineral content than local tap water, making it a popular choice among parents who prefer to control what goes into their baby's water.

Aquariums & Plants

Control exactly what goes into your aquarium or planter. RO water gives you a clean baseline to add only the minerals your fish or plants actually need.

Common Questions

Purified Water FAQ

What is reverse osmosis water?

Reverse osmosis is a multi-stage filtration process that forces water through a semi-permeable membrane under pressure, designed to reduce dissolved contaminants including chlorine, fluoride, heavy metals, and nitrates. The result is water with a neutral pH and a clean, neutral taste — noticeably different from local tap water.

Is purified RO water suitable for CPAP machines?

Purified RO water is widely used in CPAP machines because it is low in minerals. Las Vegas tap water is very hard and the mineral content can cause buildup in CPAP humidifier chambers over time. Many of our customers come specifically for this purpose and refill weekly at $0.40 per gallon.

Can I bring my own container?

Yes, we encourage it. Bring any clean bottle or jug and fill up for just $0.40 per gallon. We also have bottle cleaning stations on-site so your containers are rinsed and fresh before filling. Containers are also available for purchase in store.

How is RO water different from alkaline water?

Both start with the same multi-stage purification process. RO water stops there — minerals and contaminants are reduced through filtration, leaving water at a neutral pH of around 7. Alkaline water is then mineral-enhanced to raise the pH to 9.5–10.2. RO water is ideal for equipment, cooking, and those who want the lowest TDS water. Alkaline water is popular for everyday drinking. We carry both at our W Sahara Ave location.

Is your RO water tested regularly?

Yes. We test our water consistently using TDS measurement to make sure it meets our quality standards. We have been serving Las Vegas since 2003 as a family-owned business, and water quality is something we take seriously every day — not just on paper.
