Distilled Water for CPAP Machines, Delivered to Your Home
CPAP Water Without the Store Runs

- 1-gallon jugs: $5.75 per 3-pack, the easiest size for a nightly refill
- 5-gallon bottles: $10.09 each, for households that also use distilled water in humidifiers or other appliances
No contract, and you can change or pause your delivery anytime.
Why CPAP Machines Use Distilled Water
Your CPAP’s humidifier heats water to add moisture to the air you breathe. Tap water and many bottled waters contain dissolved minerals, and as the water evaporates those minerals are left behind as white scale in the chamber. That means more scrubbing and can shorten the life of the chamber.
Steam distillation removes essentially all minerals, which is why most CPAP manufacturers recommend distilled water. Always follow the guidance in your machine’s manual. Curious how distilled water compares to other types? Read purified vs. distilled water: what’s the difference.
How Much Distilled Water Do You Need?
Most humidifier chambers hold well under half a liter. If you empty and refill yours every night, here’s a rough guide:
- One gallon lasts about a week and a half
- A 3-pack of 1-gallon jugs covers roughly a month
- Higher humidity settings or a second machine in the house will use more
We’ll set your delivery frequency around how much you use, and you can adjust it anytime.

Frequently Asked Questions
Do I need distilled water for my CPAP machine?
Most CPAP manufacturers recommend distilled water for the humidifier chamber because it leaves no mineral residue behind. Always follow the guidance in your machine’s manual.
Why shouldn’t I use tap water in my CPAP humidifier?
Tap water contains minerals that can leave white scale in the humidifier chamber over time, which means more cleaning and can shorten the chamber’s life.
Can I use purified or deionized water instead?
Distilled water is the type most manufacturers name for CPAP humidifiers. If you want to use anything else, check your machine’s manual first. Our distilled water is steam distilled, which removes essentially all minerals.
How much distilled water does a CPAP use?
It depends on your machine and humidity settings. Most humidifier chambers hold well under half a liter, so if you refill nightly, one gallon typically lasts about a week and a half, and a 3-pack of 1-gallon jugs lasts roughly a month.
How often should I replace the water in my CPAP humidifier?
Most manufacturers recommend emptying the chamber and refilling it with fresh distilled water every day. Check your machine’s instructions for its cleaning schedule.
How much does distilled water delivery cost?
A 3-pack of 1-gallon distilled water jugs is $5.75 (about $1.92 per gallon), and a 5-gallon bottle is $10.09. See current prices and delivery fees on our pricing page.
Can I add CPAP water to my regular water delivery?
Yes. If you already get spring or purified water from us, we can add distilled water 3-packs to the same delivery. If not, we can set up a distilled-only schedule. Learn more about home water delivery.
