Indoor Asthma Triggers: How to Avoid Them

Asthma is a common, chronic health condition of the lungs which causes inflammation and constriction of the airways. As a result, it can be difficult to breathe. Those who have asthma may experience worsening symptoms or asthma attacks when exposed to a variety of different indoor air pollutants. As such, it is important to recognize and reduce the presence of such triggers to create a safe indoor environment for asthma sufferers. To do so, consult this guide to some of the most common indoor asthma triggers and how to avoid them.

Dust mites

It’s nearly impossible to find a home that doesn’t have at least some quantity of these tiny bugs in it.

How to avoid it: Wash your bedding and dust the surfaces of your home regularly. In addition, you should also consider installing a ventilation system. Mini-split ventilation systems are especially beneficial for reducing the presence of dust mites because they don’t have any ductwork for irritants to accumulate in.


This irritant is especially prominent during the spring and fall; however, it is also present in smaller quantities throughout the entire year.

How to avoid it: In addition to reducing the presence of dust mites—and several other asthma triggers—installing a ventilation system can also help reduce the presence of pollen. In addition, you should vacuum, sweep, and dust once or twice a week to avoid the accumulation of pollen on your floors and other surfaces.


Mold can release harmful spores into the air which can trigger asthma attacks.

How to avoid it: Mold thrives in moist environments, so you should try to keep the humidity in your home at a healthy level by using an effective dehumidifier or ventilation system. Humidity levels in your home shouldn’t exceed 50 percent, to help prevent mold growth.

Pet dander

It can be hard to believe that your adorable furry friend could do you any harm, but pet dander could be to blame for causing your asthma flare-ups.

How to avoid it: While getting rid of your pet is likely not something you’ll consider, you should at least try to keep them out of your bedroom and off your furniture. If possible, try to keep them outside as much as possible or make sure to bathe them frequently.

To help reduce the presence of some of the most common asthma triggers in your come, consider investing in a mini-split HVAC system.
