1. Fine atomized particles: the proportion of nebulized particles less than 5um should be more than 50%, the larger the proportion, the better the drug absorption effect, and the better the performance of the nebulizer.
2. Working noise: The noise of the compression atomizer with poor performance can reach 80 decibels, while the noise of the compression atomizer with good quality is generally less than 65 decibels.
3. Service life: the longer the service life, the better.
4. Drug residue: The lower the drug residue, the higher the utilization rate of the nebulizer, the better the performance, and the drug residue of a good household nebulizer should be less than 0.5ml.
5. Portability: The household atomizer is used alone for individuals or a family, and is developed to meet the needs of use at any time, so if the portability is good, the user can also take it with him.
