I keep reading that I need to use distilled water in my cpap humidifier. Is this actually necessary? Seems like an expensive hassle. If it’s good to drink, why can’t I use it in CPAP?
The reason they tell you to use distilled water is two-fold.
1-it prevents calcium buildup in your machine.
2-tap water may contain microorganisms that you wouldn’t want floating around in your body.
Use distilled. We bought a table-top machine to distill our water since I used so much. It was about $100 but we don’t have to lug around bottles from the store.
