Asthma Triggers

Asthma airways are hyper-sensitive to particles like dust mite debris, pollen, and VOCs. You need rapid air cleaning to dilute these triggers faster than they are generated.

info

Health DisclaimerAir purifiers can significantly reduce airborne triggers but are part of a management plan, not a replacement for medication.

Expert Guides on Asthma Triggers

Can Air Purifiers Help with Asthma Triggers?

Can Air Purifiers Help with Asthma Triggers?

We explore how reducing airborne triggers like dust mites and smoke can support an asthma management plan.

Common Questions

?Can air purifiers help with asthma?

Studies show they reduce particulate matter triggers, which can lead to fewer attacks and better sleep.

?Are ionizers safe?

We rarely recommend ionizers for asthmatics as some produce ozone. Simple mechanical HEPA filtration is safest.

?How often should I run it?

24/7 on Auto Mode. Sudden bursts of dust (like making a bed) need instant filtration.

?Does CADR matter?

Yes. Higher CADR means faster removal of triggers, which is crucial when an attack is imminent.
