Nebulizers play a vital role in medical and home health care, and their importance is reflected in many aspects:
Nebulizers can convert liquid drugs into tiny mist particles and deliver them directly to the respiratory tract, especially the lower respiratory tract. This allows the drug to act more directly on the site of inflammation or infection, improve treatment efficiency, and reduce systemic side effects.
Applicable to a variety of respiratory diseases, such as asthma, chronic obstructive pulmonary disease (COPD), bronchitis, pneumonia, etc. And used to relieve respiratory infection symptoms, promote sputum discharge, and improve the quality of life of patients.
For children, oral medications may be difficult to accept due to taste or difficulty in swallowing. Nebulization therapy provides a painless, non-invasive option that makes it easier for children to cooperate with treatment.
Nebulization is not only used for treatment but also has a positive effect on preventing respiratory diseases by keeping the respiratory tract moist and reducing the risk of infection.
Modern nebulizers are designed to be small and portable, suitable for home use or even for carrying out. Patients can receive treatment at home or while traveling without frequent trips to the hospital.
Technological advances such as compressed nebulizers and mesh nebulizers have made nebulization treatment more efficient, with smaller nebulized particles that can be better deposited in the lungs. At the same time, the noise control and self-cleaning functions of the equipment have greatly improved the user experience.
Different types of nebulizer cups and drug combinations allow doctors to adjust treatment plans according to the patient's specific condition and achieve personalized treatment.
The filter can effectively remove impurities, dust, bacteria, and other harmful substances in the air, ensuring that the air entering the nebulizer is clean. This can reduce the pollution of air quality during the drug atomization process and protect the user's respiratory health, especially for patients with respiratory problems.
The filter intercepts particles such as dust, dirt, and hair in the air to prevent these substances from entering the nebulizer. This can prevent the inside of the equipment from being blocked or damaged, extend the service life of the equipment, reduce the occurrence of failures, and ensure the long-term stable operation of the nebulizer.
The filter ensures that the nebulizer gets clean air, which helps the drug to be atomized and distributed more evenly. Clean air helps the nebulizer produce finer atomized particles, thereby improving the inhalation efficiency and treatment effect of the drug, ensuring a smoother and more effective treatment process.

It can be used for water filtration, such as in fish tanks
Disadvantages:
It cannot effectively filter fine particles, such as PM2.5, bacteria, etc.
Long-term use may breed bacteria and requires regular cleaning
Features:
Dense mesh structure woven from glass fiber or synthetic fiber
Can filter ≥99.97% of 0.3 micron (μm) particles (such as bacteria, viruses, smoke)
Commonly used in medical-grade air purification equipment
Advantages:
Highly efficient filtration of PM2.5, germs, pollen, smoke, and other particles
Suitable for medical and high-end air purification needs
Suitable for people with allergies and respiratory diseases
Disadvantages:
Expensive, cannot be washed (needs to be replaced regularly)
High filtration resistance, may affect airflow
Requires a powerful fan or compressor to be used with
Features:
Unlike ordinary filters, PSA is a gas separation technology, not physical filtration
Mainly used in oxygen generators, zeolite molecular sieves adsorb nitrogen at different pressures to concentrate oxygen
No filter is required, but the molecular sieve needs to be replaced periodically
Advantages:
Can directly separate oxygen and improve purity (up to 95%)
Low operating cost, suitable for home oxygen generators
Suitable for gas purification of continuous airflow
Disadvantages:
Cannot remove particulate matter in the air (such as dust band bacteria)
Molecular sieves have a limited lifespan and need to be replaced for long-term use
Only suitable for specific gas separation, such as oxygen and nitrogen preparation
Nebulizer filters have the following main functions:
The filter can remove dust, bacteria, allergens, pet hair, and other harmful particles in the air, ensuring that the air entering the nebulizer is clean, thereby reducing the irritation of pollutants to the respiratory tract, especially for patients with asthma, allergies, and other respiratory diseases.
The filter can prevent dust, impurities, and particles from entering the nebulizer, thereby protecting the equipment from blockage or damage, reducing the frequency of maintenance, and extending the service life of the nebulizer.
The filter ensures that the air entering the nebulizer remains clean, which helps the drug atomization to be more uniform. Clean air helps the nebulizer produce finer atomized particles, improves the inhalation efficiency of the drug, and ensures the treatment effect.
① Filter dust, impurities, and microorganisms in the air
② Protect the internal parts of the nebulizer and extend the life of the equipment
③ Improve the quality of nebulization and ensure that the patient inhales pure nebulized drugs
Daily use: High-frequency use will accelerate filter clogging, it is recommended to replace it every 1-2 months.
Occasional use: Low-frequency use will cause the filter to become polluted more slowly, and the replacement period can be extended to 3-6 months.
Severe air pollution: The filter is prone to dust accumulation and needs to be replaced every 1-2 months.
With pets or secondhand smoke: pollutants such as hair and smoke accelerate the loss of the filter, replacing it every 1-2 months is recommended.
Humid environment: mold is easy to grow, it is recommended to replace the filter every 1-2 months and keep it dry.
Dry environment: it can be appropriately extended to 3-6 months.
Children, the elderly, and patients with chronic diseases have high requirements for air quality, so it is recommended to replace the filter every 1-2 months to avoid health risks.
Dirt accumulation: Is there any obvious dust, stains, or drug residue on the filter surface?
Discoloration or deformation: If the filter changes color (such as yellowing or blackening) or deforms, it has lost its original filtering effect.
Damage: Is there any damage, crack, or wear that affects its function?
Poor atomization effect: If the atomizer's mist output decreases, it means that the filter may be blocked.
Increased breathing resistance: If you feel increased resistance during use, the filter may be blocked by particulate matter, resulting in airflow obstruction.
Mold or odor: The filter is prone to mold growth and unpleasant odors when it is damp. If you smell an odor, you should check and replace it in time.
Moisture accumulation: The filter in a long-term humid environment may accumulate water or mold and need to be replaced.
Refer to the recommended replacement cycle based on the frequency of use and environmental conditions. If the filter has been used for more than the recommended period (such as 1-2 months), you should consider replacing it even if there are no obvious signs.
If the filter cleaning effect is significantly reduced, the atomizer performance becomes worse, or it feels uncomfortable when used, this may be a sign that the filter has lost its effectiveness.
