Mold remediation is a vital part of returning to a safe and healthy living place. However, after mold has been removed, airborne spores and remaining musty smells can still adversely impact indoor air quality. Listed below are some methods to improve air quality after mold has been remediated to help revitalize the indoor space.
High-Efficiency Air Purifiers
Using HEPA (High-Efficiency Particulate Air) filters works very well to remove mold spores, unwanted allergens, and other airborne particles. Therefore, adding air purifiers to the concerned region of the structure as well as in locations of high traffic will help to clean the indoor air and help resolve a musty smell or moderate mold exposure after remediation.
Increase Ventilation
Increasing airflow in the environment is especially important when avoiding trapped air, which increases moisture. Keep windows open and use fans to facilitate increased ventilation. An energy recovery ventilator (ERV) or heat recovery ventilator (HRV) is another option for maintaining continuous fresh air flow throughout the indoor space.
Use a Dehumidifier
Since mold will continue to thrive in high humidity, it is important to maintain an appropriate indoor humidity level (ideally between 30-50%). A dehumidifier will reduce excess moisture, which can help reduce the possible regrowth of mold and keep the indoor space comfortable.
Change HVAC Filters
If your HVAC system is not changed after the mitigation, it's possible that your system can carry mold spores. Changing the filter with a HEPA-grade filter can help trap fine particles to prevent mold spore contamination. You may want to consider the option of having your HVAC ducts cleaned by a professional to remove any residual mold or debris.
Regularly Clean and Disinfect Surfaces
After the remediation, you may still have particles of mold that have settled on surfaces. Wipe down walls, floors, and furniture with an antimicrobial cleaner. Do not use bleach alone, as it does not always kill all the mold at the root level.
Utilize Natural Air Purifiers
Use houseplants such as peace lilies, snake plants, or spider plants to help improve your air quality by absorbing toxins and releasing oxygen. Be sure the plants do not hold excessive moisture, which can promote mold growth.
Use Activated Charcoal and Baking Soda
Activated charcoal and baking soda are natural odor absorbers. Bowls of activated charcoal and baking soda placed around your home can help eliminate any lingering musty smell left over from the mold.
Schedule Regular Inspections
Mold spores can be reintroduced if whatever caused the mold to reoccur is not identified, such as leaks or condensation. Conduct regular inspections of your home, especially in areas where moisture is common, such as bathrooms, kitchens, and basements. Address leaks or water damage immediately.
