Is it okay to use purified water in a CPAP machine?
Filtered water may remove some of the minerals but may not remove living organisms or other chemicals. Bottled water that has been distilled is certainly 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.
As you may gather from the information above, there is essentially no difference between purified and distilled water, aside from the purification process. Distilled water goes through distillation, while purified water is processed by other means (reverse osmosis, sand filtration, ion exchange, etc.).
- Purified water tends to be acidic and can only be recommended as a way of drawing poisons out of the body. Once this is accomplished, the continued drinking of purified water is a bad idea. Water filtered through a solid charcoal filter is slightly alkaline.
- Drinking distilled water. Yes, you can drink distilled water. However, you might not like the taste because it's flatter and less flavorful than tap and bottled waters. Some sources claim that drinking distilled water will help detoxify your body and improve your health.
- For example, many people mistakenly think that Aquafina is distilled water because it is also purified. Even though Aquafina's purification process removes some impurities and minerals from its water, it is still not considered a distilled form of water.
