Can An Air Purifier Help With Mold In Your Home?


Can an air purifier help with mold growth in your home? The mold remediation experts at iMold say yes! Mold growth is a common problem in many households in humid areas. Breathing the spores can lead to various health issues and structural damage. Dealing with mold presents many challenges, especially if it’s present in hidden areas or if it’s a persistent issue. If you’ve faced mold problems in the past, you know remediation requires identifying the root cause and proper cleanup, and you also know you don’t want to experience it again. Many homeowners wonder whether an air purifier can help prevent mold growth. In this blog, we’re here to explore the relationship between air purifiers and mold. 



  • Air purifiers only help to prevent mold growth. They can’t replace mold remediation.
  • It can prevent mold spores from spreading through the air.
  • They won’t prevent mold growth caused by moisture problems.
  • You must address hidden mold, as air purifiers can’t reach hidden spaces.
  • Always address mold growth with professional remediation and remove it at its source. 


Understanding Mold and Its Health Impacts 

Before delving into the role of air purifiers in fighting mold, it’s important to understand what mold is and its potential health impacts. Mold is a type of fungus that thrives in warm, damp environments. It reproduces through spores. These spores can become airborne and spread quickly throughout your home. When you inhale mold spores, you can experience different health problems. This is especially true for people with allergies, asthma, or weakened immune systems. Common symptoms of mold exposure include coughing, nasal congestion, throat irritation, and skin or eye irritation. 


The Role of Air Purifiers in Preventing Mold 

While air purifiers cannot replace mold remediation efforts, they can play a supporting role. An air purifier can reduce the number of mold spores and improve your overall indoor air quality. Here are several ways that air purifiers help to prevent mold growth:


1. Filtration of Mold Spores

High-Efficiency Particulate Air (HEPA) filters are the gold standard in air purification technology for capturing small particles like mold spores. Experts design these filters to trap particles down to 0.3 microns with an efficiency rate of over 99.97%. Mold spores on average range from 1 to 30 microns, so HEPA filters effectively capture them as they circulate through the air. As air passes through the HEPA filter, the microscopic fibers within the filter create a maze-like structure that traps particles, including mold spores. The filter keeps the spores from recirculating back into the room. To keep a HEPA filter working well, you must replace it regularly. 

2. Reduction of Allergens 

In addition to capturing mold spores, air purifiers can help reduce other common indoor allergens. Dust mites, pet dander, pollen, and other particles can also cause allergic reactions. Air purifiers create a cleaner and healthier environment by removing or significantly reducing these allergens from the air. This is especially helpful for anyone who experiences allergies and asthma.

3. Helps Stop Mold Growth 

Some air purifiers have additional features to stop mold growth while removing musty odors. Some of these features include:


  • UV-C Light Technology: Certain air purifiers incorporate ultraviolet (UV-C) light technology. This technology sends out short-wave ultraviolet radiation. UV-C light has germicidal properties. Germicidal properties mean it can damage the DNA of mold spores, preventing them from growing or multiplying. UV-C light can help control mold growth on the surfaces of the air purifier and nearby areas. However, it may not reach hidden areas within walls or crevices. 
  • Activated Carbon Filters: Activated carbon filters are very porous and have a large surface area. This means that they can absorb and trap odorous molecules. These filters help reduce the musty smells often associated with mold growth. However, activated carbon filters do not kill mold spores. They destroy the molecules that cause the musty smell. 


Limitations of Air Purifiers in Mold Control 

While air purifiers significantly improve indoor air quality and reduce airborne mold spores, they aren’t the magic cure for mold. Let’s talk about some ways air filters can’t help with mold.

1. Air Filters Can’t Help With Hidden Mold 

Air purifiers can only filter mold spores that are present in the air. They cannot access or help with mold spores that are not in the air. For example, mold that hides within walls or rests in corners or on ceilings. Mold colonies hidden behind drywall, underneath carpets, or within HVAC systems require professional inspection and remediation.


2. Won’t Prevent Moisture Problems 

Air purifiers do not prevent mold growth caused by underlying moisture problems. They can lessen airborne mold spores but do not always address the root cause of mold growth. Mold growth is usually caused by too much moisture. To effectively control mold, it’s important to identify and address water leaks. Look at where you have poor ventilation and high humidity levels in your home. Common areas are attics, basements, and bathrooms. 


An Air Purifier Isn’t Enough: Addressing Mold at Its Source 

An air purifier alone cannot completely remove mold from your home. The key to mold control lies in addressing the problem at its source. Mold growth is often a symptom of excess moisture and inadequate ventilation. To effectively fight mold, we recommend following these steps in conjunction with your air purifier:

  1. Identify the source of moisture:
    Inspect your home thoroughly to locate areas of excessive moisture. Common culprits include leaky pipes, roof leaks, high humidity levels, and poor ventilation in bathrooms and basements.
  2. Fix leaks and water issues:
    Once you identify the source of moisture, address any leaks or water-related problems. Repairing leaks and removing any excess moisture can prevent mold from thriving.
  3. Improve ventilation:
    Proper ventilation helps reduce humidity levels and prevents dampness in the building. Use exhaust fans in bathrooms and kitchens. In addition, place fans throughout your home to help assist with airflow.
  4. Use dehumidifiers:
    In areas with consistent high humidity levels, it is worth considering the use of dehumidifiers to reduce moisture in the air.
  5. Remove materials with mold:
    If mold has already grown on porous materials like drywall, furniture, or carpet, it’s important to remove and replace them. Otherwise, the mold will continue to spread further.  


Fight Mold with iMold! 

Air purifiers are valuable tools for improving indoor air quality and reducing airborne mold spores. However, consider them a supplementary measure rather than a standalone solution for mold control. Proper mold mitigation often requires an expert team. Homeowners should proactively maintain their homes to prevent mold growth by promptly fixing leaks, ensuring proper ventilation, and controlling humidity levels. By combining these preventive measures with air purifiers, you can help prevent mold. If mold issues continue or you suspect mold growth in hidden areas, it’s time to seek professional help! A mold remediation specialist will ensure effective and safe mold removal.
