Why Mold Is More Than a Surface Problem
Mold is more than just an unsightly problem. It can trigger allergies, aggravate asthma, and lead to chronic respiratory issues when left unchecked. With indoor air quality becoming a bigger concern than ever, many people are turning to air purifiers to protect themselves from airborne mold. But do air purifiers actually work against mold? Let’s explore the science.
What Is Mold, and Why Is It Harmful?
Mold is a type of fungus that grows in damp, humid environments. It reproduces by releasing tiny spores into the air. When inhaled, these spores can cause a range of symptoms, including coughing, sneezing, headaches, and skin irritation. For people with asthma, mold exposure can be particularly dangerous.
Can Air Purifiers Remove Mold Spores?
Yes—many air purifiers are effective at capturing mold spores from the air. HEPA filters, for example, are designed to trap particles as small as 0.3 microns, which includes most mold spores. However, simply capturing spores isn’t always enough.
Here’s why:
-
Mold spores can remain viable even after being captured in a filter.
-
If not replaced regularly, a filter can become a breeding ground for mold.
-
Air purifiers that rely solely on passive filtration may not address mold on surfaces where it often thrives.
Why Active Purification Works Better
Unlike passive purifiers, Airea uses an active technology called photocatalytic oxidation to generate stable H₂O₂. Using UV-C light and a specialized catalyst, Airea creates H₂O₂ molecules from ambient moisture and oxygen at safe concentrations (10-20ppb). These molecules target mold spores and surface mold at the molecular level. This approach doesn't just filter mold spores from the air—it actively destroys them.
Surface Mold: The Hidden Threat Most Purifiers Miss
Most mold doesn't float through the air—it grows and spreads on surfaces like window sills, bathroom tiles, or inside HVAC ducts. Airea's active purification technology goes beyond the air, helping to reduce microbial contamination on nearby surfaces.
This added layer of defense is especially important for:
- Homes with high humidity or past water damage
- Bathrooms, kitchens, and basements
- Families with allergies or immunocompromised individuals
Complementing HEPA with H₂O₂
Already using a HEPA purifier? Great. Airea works alongside it by targeting what HEPA might miss:
-
Smaller biological particles that pass through filters
-
Mold spores that land on surfaces and grow
-
Airborne pathogens that filters can’t neutralize
Together, they offer a more complete purification strategy.
The Bottom Line: Air purifiers can absolutely help reduce the presence of mold—but only if they use the right technology. Airea’s filter-free, H₂O₂-based system actively destroys mold in the air and on surfaces, giving you a smarter, more comprehensive solution for protecting your home and your health.
