Setting up your humidifier

Got questions about how to set up your humidifier? Find the answers to the most frequently asked questions about humidifier setup here.

Q. Can I put my device on top of the humidifier?

A. Your device should always be placed either at the same level or above the humidifier to reduce the risk of water entering the device. To further ensure that water doesn't enter your device, disconnect the humidifier and drain the water before transporting it.

Q. I have a full face mask. Will I need more water during the night?

A. A full face mask should not change the amount of water used each night. If you had a mouth leak before, you could have been losing air and humidity through your mouth, in which case you should use less water now.

Q. Does heated humidification wear out my mask and hoses faster?

A. No. The tubing supplied with devices can withstand far higher temperatures than the heat generated by the humidifier.

Q. Should I turn on my humidifier before I go to bed to make sure the water is warm first?

A. If you find the air dry and irritating, you may want to turn your humidifier on 20 minutes before going to bed.

Q. I usually use my humidifier only in the winter months when the heater is on and the air is drier. Should I be using it all year round?

A. If you're finding that you have nasal congestion or dryness at other times of the year, then you should probably use your humidifier. The added humidification will most likely increase the air comfort since it’s more moisturised.

Q. If I run out of distilled water once in a while, is it OK to use tap water? 

A. Yes you can but using distilled water will help to maximise the life of the water tub and reduce mineral deposits. Therefore, we recommend using distilled water in your humidifier tub.
