Yes, HEPA filters have been proven to capture and remove mold spores from the air effectively. They can trap particles as small as 0.3 microns and are designed to protect against airborne particulates such as dirt, dust, smoke, pet dander, pollen and even bacteria. In addition to capturing these particles in the air, they keep them from circulating back into your home or office environment. This is why most HEPA air cleaners are highly recommended for people with allergies or those looking to reduce exposure to harmful contaminants like mold spores. It's important to note that while a HEPA filter can help reduce exposure to mold spores, it cannot eliminate them. The best way to get rid of mold is by tackling its source – moisture buildup around windows, walls and other home areas.
