Asthma and the quality of the air you breathe are closely linked. Many people with asthma wonder if an air purifier can make a noticeable difference. Below, you can read about what an air purifier can and cannot do for asthma symptoms.
What triggers asthma symptoms indoors?
For many people, asthma symptoms are triggered by airborne irritants: dust mites, pollen, pet allergens, particulate matter from cooking or the outside air, and sometimes cigarette smoke or strong odors. The more of these irritants present in the indoor air, the greater the chance of symptoms such as shortness of breath, coughing, or wheezing.
What an air purifier can do
An air purifier with a HEPA filter captures a large portion of these irritating particles from the air: particulate matter, pollen, dust mite debris, and pet dander. By lowering the concentration of these substances in the air, an air purifier can contribute to a more pleasant indoor climate for people with asthma. Many people find that the air feels fresher and that certain triggers are less present when the device runs regularly, especially in the bedroom where you spend most of your time.
What an air purifier cannot do
An air purifier is not a medical device and does not treat asthma. The device only filters particles from the air; it has no effect on the underlying condition and does not replace any medication or treatment prescribed by your doctor. If you have concerns about your symptoms or medication, always consult your GP or pulmonologist. You can find more background information on asthma and airborne triggers at the Longfonds.
Combine with proper ventilation
An air purifier does not replace fresh outdoor air. Continue to ventilate according to the usual approach, even if the air purifier is running at full capacity. The combination of adequate ventilation and air purification generally provides the best results for a healthy indoor climate.
What should you look for when choosing?
- HEPA13 filter: captures up to 99.97% of particulate matter, pollen, and other small particles.
- Sufficient capacity: choose a CADR value that matches the floor area of the room — calculate this using our CADR calculator.
- Silent operation: especially for the bedroom, where the device often needs to run at night — see our dB guide.
- Regular use: an air purifier works best when it runs consistently, not just when symptoms occur.
Our advice
The AirPure Plus PA244 features a HEPA13 filter with 4-stage filtration, a CADR of 260 m³/h for rooms up to 55 m², three settings with an automatic mode, and a quiet night mode between 28 and 60 dB. In our experience, this is a suitable choice for those looking to improve air quality in the bedroom or living room as a supplement to the regular management of asthma symptoms.
Conclusion
An air purifier can contribute to fewer airborne irritants and thus improve comfort for people with asthma, but it is not a replacement for medical treatment. Combine the use of an air purifier with regular cleaning, ventilation, and the advice of your doctor.
