What Is a Nebuliser and Who Needs One?
A nebuliser (sometimes spelled "nebulizer") is a medical device that converts liquid medication into a fine mist or aerosol, allowing it to be inhaled directly into the lungs. Nebulisers are commonly prescribed for people with asthma, chronic obstructive pulmonary disease (COPD), bronchitis, cystic fibrosis, and other respiratory conditions.
While inhalers work well for many patients, nebulisers are often recommended when higher doses of medication are needed, when a patient has difficulty using an inhaler (common in young children and elderly patients), or when medication needs to be delivered over a longer period.
Types of Nebuliser: Which Is Right for You?
Compressor (Jet) Nebulisers
The most common type for home use, compressor nebulisers use compressed air to turn liquid medication into an aerosol. They are reliable, affordable, and compatible with most nebuliser medications. Models like the Airmed 1000 and the Clement Clarke Medix range are popular choices for home respiratory care in the UK.
Pros: Affordable, reliable, works with all medication types
Cons: Louder than other types, bulkier, requires mains power (though some have battery options)
Ultrasonic Nebulisers
Ultrasonic nebulisers use high-frequency vibrations to create the aerosol. They are quieter and faster than compressor models, but are not suitable for all medications — particularly viscous solutions or suspensions like budesonide.
Pros: Quiet, fast treatment times
Cons: Not compatible with all medications, more expensive
Mesh Nebulisers
The newest technology, mesh nebulisers push liquid through a fine mesh membrane with thousands of tiny holes to create the aerosol. They are the smallest, quietest, and most portable option. The Cirrus 2 Nebuliser is an excellent example of a compact, portable unit.
Pros: Very portable, quiet, fast, battery-powered
Cons: Higher cost, mesh requires careful cleaning
Key Features to Consider
Portability
If you need to nebulise while travelling or at work, a portable battery-operated nebuliser is essential. Mains-only units are fine if treatment will always be at home.
Noise Level
For treating children at bedtime or using at work, a quieter ultrasonic or mesh nebuliser may be preferable. Compressor nebulisers can produce 50–60 decibels — roughly the volume of a conversation.
Treatment Time
Faster nebulisation means shorter treatment sessions. Mesh and ultrasonic nebulisers typically deliver medication in 5–8 minutes, while some compressor models can take 10–15 minutes per session.
Medication Compatibility
Check that the nebuliser is compatible with your prescribed medication. Compressor nebulisers work with virtually all nebuliser solutions, while ultrasonic models may not work with suspensions. Always confirm with your pharmacist or GP.
Replacement Parts Availability
Nebuliser masks, tubing, and chambers are consumables that need replacing regularly (typically every 3–6 months). Choose a nebuliser from a brand with readily available replacement parts — we stock a full range of nebuliser accessories for all our machines.
How to Use a Nebuliser
- Wash your hands thoroughly
- Measure and add the prescribed medication to the nebuliser cup
- Attach the mouthpiece or face mask
- Switch on the nebuliser and breathe normally until the medication is finished (usually 5–15 minutes)
- Clean the nebuliser cup, mask, and mouthpiece after each use according to the manufacturer's instructions
Nebuliser Accessories and Replacements
To maintain hygiene and treatment effectiveness, replace these parts regularly:
- Nebuliser masks (adult and paediatric) — every 3–6 months
- Tubing — every 3 months or when discoloured
- Nebuliser cups/chambers — every 6 months
- Air filters — as recommended by the manufacturer
