Why do CPAP machines require distilled water?

Distilled water prevents mineral buildup in the humidifier, reducing the risk of bacteria growth and extending the life of your CPAP equipment.

Can I use tap water in my CPAP machine?

Tap water contains minerals, bacteria, and impurities that can cause buildup and damage the humidifier over time. Always use distilled water when possible.

What happens if I don’t use distilled water?

Using non-distilled water can lead to mineral deposits, bacterial growth, and potential machine damage, reducing performance and hygiene.

Can I make my own distilled water for CPAP?

You can boil water and collect the steam, but it may not be as pure as store-bought distilled water. A home distiller is the best DIY option.

Is bottled water safe for CPAP use?

Not all bottled water is the same. Only distilled water is recommended. Spring, filtered, or purified water may still contain minerals.

Can I use CPAP without water?

Yes, but it may cause dryness and irritation. Some machines allow you to turn off the humidifier or use a heat moisture exchanger (HME) instead.

How often should I replace the CPAP humidifier water?

Daily—always empty the humidifier each morning, rinse it, and refill it with fresh distilled water before use.

What if I don’t have distilled water for my CPAP?

For a short time, filtered or bottled water is better than nothing, but clean your humidifier thoroughly afterward to avoid buildup.
