Using distilled water in your CPAP humidifier is important. Even though tap water is convenient for many users, manufacturers of CPAP equipment recommend the use of distilled water for many reasons. Tap water could contain organisms and minerals that you can’t risk breathing in. These minerals also build up on your equipment and can break down the material.

The Downsides Of Using Tap Water In Your CPAP Humidifier

Using a Humidifier With CPAPWhen choosing the best water to use in your humidifier, it is important to keep in mind that even after boiling tap water, some minerals such as magnesium, iron, and calcium are not eliminated and the water may remain ‘hard’. Boiling might kill microbes, but it can’t fully eliminate the chemical contaminants. 

Because these minerals are abrasive, when they accumulate, they can destroy the water chamber and even the rest of the machine. The harsh nature of these minerals can cause the physical breakdown of the plastic and other material on your equipment. If your only option is tap water, you can soak the reservoir in white vinegar to remove the build-up of minerals.

The Best Water To Use  While Traveling?

Water that is not safe to drink will be unsafe to inhale. Using tap water will expose you to chemicals such as chlorine, ammonia, and bleach, and harmful pathogens as well.

 If you are unsure of or do not trust the water supply, do not use it in your humidifier. It is easier to look for the nearest pharmacy and buy distilled water. 

Some CPAP users will temporarily use bottled water until they have access to distilled water. Using distilled water minimizes exposure to risks to both yourself and your equipment. 

If finding safe water is a problem, you can forego the use of your humidifier until you can access distilled water, or get back home.

Benefits of Distilled Water 

Distilled water keeps away bacteria and helps your CPAP equipment run smoothly. Using distilled water on your humidifier also ensures the right amount of pressure from your equipment. Using a humidifier directly exposes your lungs to the water. Adding scented oils, soaps or water softeners will definitely expose you to harmful chemical fumes such as alcohol, chlorine, and bleach. This is why using plain distilled water is crucial to your health.
