How Air Purifiers Can Remove Mold Spores from the Air

Mold is a persistent indoor air quality issue that can pose serious health risks, especially for individuals with allergies, asthma, or weakened immune systems. Whether caused by leaks, humidity, or flooding, mold growth releases tiny airborne spores that can spread throughout your home or workplace. The good news? A high-quality air purifier can help remove mold spores from the air and prevent respiratory issues.

What Are Mold Spores?

Mold spores are microscopic reproductive particles that mold releases into the air. They can settle on surfaces and grow into new mold colonies if they land in damp or humid areas. Since they are lightweight, they can stay suspended in the air for long periods, making them easy to inhale.

How Do Air Purifiers Remove Mold Spores?

1. HEPA Filtration: The Gold Standard

The most effective air purifiers for mold spores use True HEPA (High-Efficiency Particulate Air) filters, which can capture 99.97% of airborne particles as small as 0.3 microns. Since mold spores typically range from 1 to 30 microns in size, a HEPA filter can effectively trap them, preventing them from circulating in your indoor environment. Airpura purifiers have Super HEPA 14 which can capture 99.99% of airborne particles ≥ 0.3 microns

2. Activated Carbon for Odor Control

Mold doesn’t just release spores—it also produces musty odors and volatile organic compounds (VOCs) that can cause irritation. Air purifiers equipped with activated carbon filters can absorb these odors and chemicals, improving overall air freshness. Airpura has 18lbs-26lbs of custom blended activated carbon (the most amount in one purifier on the market!)

3. UV-C Light Technology

Some air purifiers feature UV-C (ultraviolet-C) light to neutralize airborne mold spores. UV-C radiation damages the spores’ DNA, preventing them from reproducing and forming new mold colonies. Airpura purifiers have a UV-C light which are non ozone emitting

4. Powerful Air Circulation

An effective air purifier continuously cycles air through the filters, reducing the overall concentration of mold spores indoors. The faster the air exchange rate (measured in ACH—Air Changes per Hour), the quicker the purifier removes airborne mold particles. Airpura purifiers have 360° air distribution which allows for purification for up to 2500 sq. ft with 2 air exchanges an hour

Additional Steps to Prevent Mold Growth

While an air purifier is essential for reducing airborne mold spores, it’s also important to tackle the root cause of mold:

· Control humidity levels (keep indoor humidity below 50%)

· Fix leaks and improve ventilation

· Use a dehumidifier in damp areas

· Clean and inspect HVAC systems regularly

Clears the VOCs

I bought three of these in Dec 2024 when my flooring was refinished, one for each bedroom. It's been a life-saver, being able to live in our house while VOCs are gassing off downstairs, knowing the rooms are clear of chemicals - no smell at all - because of these amazing air purifiers. We leave them on all the time. One of them, however, is oddly louder than the other two, and not sure why.

Does not draw air into filter

Quickly after receiving two of these units I realized the air does not draw into the unit enabling the air to be pulled through the filter and released. The filter is designed in my opinion poorly as it blows air from the top and is assumably drawn in from the bottom. The problem is there is no air being drawn in from the unit. Essentially it is cavitating and I ran a test using a product called smoke in a bottle which shows even the slightest air movement. I placed the smoke in a bottle about 1 ft away from the unit on the lower side which is supposed to be the intake side and puffed smoke. The results were that the smoke was pushed away from the unit as opposed to pulling it in to filter it. I tried this multiple times with the same results. After contacting the dealer and the manufacturer originally they thought something was wrong as hearing those details anyone would suspect. Upon their investigating of the unit the response later was that's the way it's supposed to work. In my opinion that's the issue is that it does not work and in order to filter error it must be pulled through the filter and cycled out. The air around the unit seems to cavitate and I can only imagine if it cannot pull air in from one foot away how in the world is it going to pull air in across the room? Again my opinion it's not going to. I wanted to attach a video of an experiment that I did with the smoke in the bottle but I did not see a link that gives me the ability to upload the video. Just my opinion again but if I were going to purchase a unit I would look elsewhere then this unit.

Thank you for sharing your experience and observations. However, the method used to test airflow in this case may not provide an accurate representation of the unit’s performance. The placement of the smoke bottle was in a turbulence zone and near the exhaust, which naturally causes air movement away from the unit rather than towards it. If the smoke had been introduced at the intake, the results would likely have been different.

That being said, we understand that the unit did not meet your expectations, and we’re glad to hear that you were able to return it and receive a full refund from the dealer. We appreciate your feedback and hope you find a product that better suits your needs.

Small and Sturdy

This unit is actually smaller than I thought it would be and it is really well put together and sturdy. I don't see any visible dust floating in the air when I have it on, like I normally do.

Great

I used this filter when I cooked a steak to clean out the smoke from the room. Worked very quickly and reduced the smell! Pleased with the purchase

C700DLX is a great air purifier

After experiencing persistent asthma exacerbations and wheezing episodes in my newly constructed home, I systematically investigated potential environmental triggers. Through a process of elimination, I identified elevated volatile organic compound (VOC) levels likely originating from construction materials and off-gassing furnishings. Implementing Airpura's air purification system with medical-grade activated carbon filtration proved transformative - I successfully discontinued daily montelukast and antihistamine regimens while achieving sustained respiratory relief. This solution effectively addressed the indoor air quality challenges inherent to new builds, demonstrating remarkable efficacy in neutralizing airborne chemical contaminants. I commend Airpura for engineering a purification technology that restored my respiratory health and living environment!
