Air Purifiers FAQs: Do Air Purifiers Help With Mold?

When you consider the health and well being of your family, It’s natural to wonder “do air purifiers help with mold?”

Mold spores can cause allergic reactions and illnesses, so you’ll want to inspect and clean your dwelling on a regular basis and free of moisture caused by leaking water.

Air purifiers will not completely solve mold problems all by themselves but they definitely can help with mold: According to the Environmental Protection Agency’s Guide to Air Cleaners in the Home, “Portable air cleaners and furnace/HVAC filters may remove some of the particles generated by mold. In some cases, they may also help reduce odors, but they will not resolve a mold and moisture problem.”

More advanced equipment is used to remove mold. The EPA notes in another edition of its report on air cleaners that ultraviolet germicidal radiation or UVGI cleaners can destroy “molds that are airborne or growing on HVAC surfaces (e.g., found on cooling coils, drain pans or ductwork.”

The air purifying system you install can include in-duct particle removal. As the EPA puts it, “Most mechanical air filters are good at capturing larger airborne particles, such as dust, pollen, dust mite and cockroach allergens, some molds, and animal dander.” Air filters are rated by their minimum efficiency reporting value (MERV) ranging from 1 to 20. The EPA reports that air panels with a MERV of 1-4 can trap some mold spores, so they can provide a useful role in your air purifier setup.

Preventing Mold Growth

Mold tends to grow in moist conditions, so make sure to periodically tour your property, looking for cracks and signs of leaks. Sealing all potential entry points for water also helps keep out the wind, which makes it cheaper to keep your home warm in winter and cool in the summer. If you detect a mold infestation, it would be prudent to contact mold eradication professionals to help take care of the problem safely and efficiently.

Remember to Change Filters on a Regular Basis

It makes sense to use air purifiers inside your home, especially if you have children, elderly people or anyone with a health issue that would be affected by poor air quality. To get the most out of your home air purifier, make sure to read the manufacturer’s recommendation on how often you should change the filter. Then put a reminder in your calendar, just as you would to routinely swap out batteries in your home’s smoke alarms.
