Yuwell 403M Air-Compressing Nebuliser

The Yuwell 403M is a home-focused compressor nebuliser with an oil-free vacuum motor design — eliminating any risk of oil contamination in the medication path. The unit produces fine medication particles delivered via the precision connecting port, with one-tap operation and a safety hook for the atomising tube that keeps the workflow clean. Sub-60 dB noise level suits family bedrooms and paediatric use.

Who it's for

Households managing asthma, COPD, bronchitis, or paediatric respiratory infections at home. The 403M sits in the middle of the Yuwell home nebuliser range — quieter than the entry 403T, less feature-rich than the 403AI. Choose by noise sensitivity and budget. If you need clinical-duty 24-hour operation, step up to the 407A.

Frequently Asked Questions

How does the 403M compare to the 403AI and 403T?
403T is the simplest entry unit. 403M adds an oil-free vacuum motor and tube safety hook (this product). 403AI is similar to the 403M but slightly higher feature spec. 407A is the clinical-grade option with 24-hour duty cycle and ≤55 dB noise.

Why does "oil-free" matter?
Some compressor nebulisers use oil-lubricated pumps; oil can theoretically reach the medication path over time. Oil-free designs eliminate this contamination concern entirely.

Can children use it?
Yes — paediatric mask included. The ≤60 dB noise is comfortable for most children, though anxious kids may prefer the silent M102 mesh nebuliser.
