Using a humidifier

How can using a humidifier improve the comfort of therapy?

Using a humidifier can make a positive difference to your therapy comfort and experience. By warming and moistening the air you're breathing, it helps prevent you having a dry nose and throat and can help you keep your mouth closed while you sleep.

If you don't have a humidifier, talk to your ResMed accredited outlet or doctor about getting one.

What is 'rainout'?

You might have heard the term 'rainout' in reference to humidification. Basically rainout is condensation building up in the tube. If you have rainout, you might hear a gurgling sound in your tubing when you breathe on therapy.   

Here's what you can do to reduce rainout:

  • Use ResMed's Climate Control humidification solution, which is designed to provide enough humidification to help you breathe comfortably, while keeping rainout at a minimum. Make sure you're using a ClimateLine™ heated tube.
  • If you're still experiencing rainout, try turning the humidity level down a little.
  • Rainout can happen if your bedroom gets too cold at night, so try to keep your room warmer overnight.
  • If you’re not using ClimateLine, to keep your tubing (and the air travelling inside it) warmer during the night, you can use a tubing wrap.
