There are many opinions on what type of water to use in a CPAP humidifier. The important thing to realize is that water is never just pure water, there is always something dissolved in it, and it's the dissolved stuff that can be the cause of concern or possible problems.
When there are germs in the water, we boil it to make it safe, and municipal water supplies add chlorine to kill and prevent the growth of germs. When there are too many minerals in the water, we soften it to remove those minerals. Filters are used to remove sediment that's dissolved in water.
Manufacturers often recommend that you use distilled in your CPAP machine because distilling water solves all of these problems.
The safety and quality of your water supply may be the key consideration in deciding whether to use distilled, boiled, filtered or tap water in the humidifier. Boiling water will kill microbes, but it will not remove minerals or chemical contaminants. Filtered water may remove some of the minerals but may not remove living organisms or other chemicals. Bottled water that has been distilled might be the safest option.
As for whether you're required to use distilled water in the CPAP humidifier: most manufacturers do recommend the use of distilled water. According to ResMed’s product website, the use of distilled water "will maximize the life of the water tub and reduce mineral deposits." The site also points out that it's okay to occasionally use tap water to clean the equipment. But since the water tub is typically replaced on a regular basis — perhaps every 6 months — maximizing the product life may not be a major concern. The concentration of minerals, that is the water hardness, will depend on your water supply.
If you're traveling to a part of the world where you don't trust the water supply, you should use distilled water in the humidifier. If the water's not safe for you to drink, it's probably not safe to put it in your CPAP machine. Using distilled water in this case will minimize your exposure to potentially harmful substances. In addition, the use of tap water within Neti pots in Louisiana has led to a few reports of harmful parasite infections affecting the brain. Even though the same problem has never been reported with the use of a CPAP machine, it's a concern for some people.
Ultimately, you must be aware that you'll be exposing your lungs to the water placed in the CPAP humidifier, which may motivate you to clean it on a more regular basis. Moreover, you must not place any substances in the tank that would be harmful to breathe. Perfumes, cologne, or scented oils are not a good idea. Exposure to fumes from bleach, alcohol, chlorine or ammonia may damage your lungs. The use of moisturizing, antibacterial, and glycerine-based soaps is also discouraged. Water softeners and descaling agents should also not be used in the reservoir.
If you question the safety or quality of your water supply, err on the side of caution and use distilled water in your CPAP humidifier. This is especially true if you are traveling in regions of the world with unsafe water supplies. If distilled water is not available use bottled drinking water. Tap water may lead to mineral deposits accumulating in your CPAP humidifier tank, and may be a concern for potentially undesirable exposures or other effects.
