What Triggers Asthma?

Asthma differs from person to person. What can cause a flare-up for you may not be a problem for others. Outdoor irritants like pollen, smog, fire, and pollution can quickly cause issues for those with asthma. Pollen, mold, dust, or pet dander can be triggering. Cigarette smoke, chemicals, paint fumes can also have you reaching for your inhaler. Exercise induced asthma is also common. That’s why you must monitor when your symptoms start, pay attention to what seems to make them worse, what you were doing at the time of your flare-up, and what was going on around you to determine what your specific asthma triggers are. It will help you know what to avoid and how best to protect yourself in the future from a severe asthma attack.

Air Purifiers and Asthma

One of the most effective ways to cut down on asthma and even allergy issues at home is with an air purifier. Air purifiers pull harmful airborne particles and pollutants out of the air, trap them in a filter or series of filters, and release clean and purified air back out. 

The best air purifiers use a HEPA filter as the primary filter. HEPA filters can trap 99 percent of the smallest airborne irritants floating around in the air inside your home. Mold, pollen, dust, pet dander, and even viruses and bacteria can be caught and trapped with these high-efficiency filters.
