Do Air Purifiers Help Asthma?

If you’re wondering whether or not air purifiers really do help asthma, the answer is yes and we will explain just why.


To best explain how air purifiers help asthma, it’s important to start with triggers. Things like mould, dust, and smoke can trigger asthma symptoms and many of these are found in your home. Think that keeping your house clean is sufficient to prevent these triggers? Think again, as these allergens can be in the air even after you’ve taken every step possible to keep your surfaces clean.

Things like dust, pollen, and other irritants can make their way into your home through open windows and doors and even on the clothing of those entering the home. Chemical irritants and fragrances can come from the very products that you use to keep your house clean, as well as from things like perfumes, air deodorizer sprays, and detergents.

Then there’s Fido and Fluffy adding to the problem with their dander. Even a clean cat or dog is still letting dander onto your furniture and into the air and yes, even those that are lovingly groomed on the regular.

And then there’s smoke—and not just from cigarettes either! We all know that cigarette smoke is bad for asthma, but did you know that enjoying a cozy fire in the fireplace or stove can trigger and worsen asthma symptoms? And even enjoying a nice barbecue or bonfire in your backyard can pollute the air in your home through open windows and doors, and cracks, as no home is perfectly sealed.

How Air Purifiers Help

Along with following doctor’s orders and taking the required medication; avoiding triggers is the best way to keep your asthma in check. Try as you might to avoid them, it’s not really possible to keep the air in your home completely free of allergens and irritants, which is where air purifiers come in.

Air purifiers keep the air in your home clean so that you can breathe better. The filters in air purifiers trap things such as:

• Dust
• Dust mite faeces
• Mould spores
• Pollen
• Pet dander
• Smoke
• Odors
• Airborne chemicals
• Gases

A good quality air purifier uses different filters to trap these pollutants and is able to catch as much as 99.97 percent of these. A combination of HEPA filters, activated carbon or charcoal filters, and even UV-C filters all work together to trap the different types of pollutants found in the air of your home.

Air purifiers are recommended by the National Asthma Council of Australia as a way to help manage and live better with asthma.

The best air purifier for you will depend on things such as the size of the room it will be used in and the type(s) of filter. They vary in price to suit different budgets and offer various features to suit your needs and preferences, such as automatic air quality control sensors and alerts to tell you when it’s time to change your filter. Speaking of the filter; changing it as required can help you make the most of an air filter so that it works efficiently.
