Cleaning your nebuliser

All nebulisers need to be maintained and cleaned. If your health care professional arranges one for you, they should give you information about this. 

You should always follow the instructions from the nebuliser’s manufacturer.

It can be time-consuming to clean and maintain your machine, so you’ll need to build this into your routine. It’s important to clean and dry your nebuliser thoroughly every day if you use one regularly.

Wash your nebuliser after each use by:

  • washing your hands
  • disconnecting the mask, mouthpiece and chamber
  • washing the individual parts in warm soapy water
  • shaking off excess water and leaving the parts to air dry on a clean tissue or kitchen paper towel

You may also be advised to disinfect the nebuliser regularly.

Parts such as mouthpieces, masks, tubing, filters and the nebuliser’s chamber need to be changed regularly, at least every 3 to 4 months.

To avoid cross infection, you should never use other people’s mouthpieces, masks or tubing.

Risk of infection from nebulisers

Hospitals assess the risk of infections caused by using nebulisers and have clear procedures to avoid spreading infections. These may include using nebulisers or their parts only once, and processes to clean and decontaminate them. At home, you should also be aware of the risk of infection. Nebulisers can be contaminated by infections in your airways and bacteria in the environment. Any fluid left in a nebuliser can easily grow bacteria.

So it is very important you know how to clean and dry your nebuliser after every use.
