Start with the nebuliser model code. A compressor nebuliser and a mesh nebuliser can use very different parts, even from the same brand.
Identify the part and device
Check the device code and the part being replaced: mask, mouthpiece, air tube, filter, chamber or mesh cap. Match both codes in the manufacturer documentation.
Check the intended accessory
Some accessories have specified users or sizes. A child mask and an adult mask are separate accessory choices. Read the manufacturer’s stated compatibility.
Check care instructions
Follow the model’s instructions for cleaning and replacement. Buying an accessory does not establish that a nebuliser or medicine is appropriate for a particular person.
See the documented nebulisers & accessories options or find supplies for an exact device.
