The BiLevel ventilator machine

The BiLevel ventilator works when connected to a mains electricity supply. When the ventilator is turned on, it sucks in air through a filter from the room around you and blows it out under a pressure through a tube. The air is then delivered to you using either a mask that covers your nose (referred to as a nasal mask) or via a mask that covers your nose and mouth (referred to as a full face mask). Your prescriber will advise you on the most suitable type for you.

The BiLevel ventilator delivers two levels of pressure: a higher level of pressure when you breathe in and a lower pressure when you breathe out.

Equipment cleaning

Your BiLevel ventilator is a medical device that should be treated with care and damp dusted weekly. Always ensure your BiLevel ventilator is unplugged from the main supply before you clean it. Your BiLevel ventilator should not be stored on the floor because this is the dustiest part of a house. We will service your BiLevel ventilator annually and as required. Please refer to your BiLevel ventilator instruction manual for cleaning advice.


If you are living in an area with repeated power cuts or if you are used to travelling to places where mains electricity is not available, then you may need to discuss a battery option with your prescriber. There are a number of options available depending on your specific needs.
