Following the hazardous chemical incident in Garden Grove on May 21, local officials issued temporary evacuation orders for areas of Garden Grove as well as a health advisory for the general public. While there is currently no confirmed leak of chemicals on the ground or in the air, some homeowners may still be rightfully concerned about the impact poor outdoor air quality can have inside the home.
During events like this, outdoor pollutants can enter homes through ventilation systems, duct leaks, windows, and doors. Taking proactive steps to improve your indoor air quality can help reduce these contaminants and create a healthier indoor environment for your family.
At Cole Services, we’re here to keep homeowners informed and prepared during these types of events. Below are several practical recommendations that can help keep you and your family safe.
Upgrade to a MERV 13 HVAC Filter
One of the most effective ways to improve indoor air quality is by upgrading your HVAC system filter. Many homes use standard filters that are designed mainly to protect HVAC equipment rather than improve air filtration.
A MERV 13-rated filter can capture smaller airborne particles, including:
- Smoke particles
- Dust and allergens
- Certain airborne contaminants
- Fine debris from outdoor pollution
These filters provide a higher level of filtration compared to basic fiberglass filters. However, it is important to ensure your HVAC system can properly handle a higher-efficiency filter. A professional inspection can help determine the best option for your system.
Consider an Air Purification System
For homeowners looking for additional indoor air protection, installing an air purification system such as an Air Scrubber can help improve air quality throughout the home.
Air purification systems work alongside your HVAC system to reduce airborne particles, odors, and contaminants while improving overall air circulation. Depending on the system, they may also help reduce bacteria, mold spores, and other pollutants inside the home.
During periods of smoke or chemical exposure, these systems can provide an added layer of indoor air protection for families concerned about air quality.
Seal Duct Leaks
Leaky ductwork is one of the most overlooked causes of poor indoor air quality. Gaps or cracks in your duct system can allow outside contaminants to enter your HVAC system and circulate throughout your home.
Professional duct sealing helps:
- Improve indoor air quality
- Reduce airborne contaminant entry
- Improve HVAC efficiency
- Maintain more consistent airflow
Sealing duct leaks can also help lower energy waste and improve overall system performance.
Run Your HVAC Fan Continuously
During smoke or chemical incidents, running your HVAC fan continuously can help circulate and filter the air inside your home more effectively.
Keeping the fan running allows air to pass through the filtration system more frequently, helping reduce airborne particles and improve circulation throughout the home.
If your system has a fan-only setting, using it during poor outdoor air conditions may help improve indoor comfort and air quality.
Replace HVAC Filters More Frequently
When the outdoor air quality is poor, HVAC filters often become dirty much faster than normal. A clogged filter reduces airflow and limits your system’s ability to filter contaminants effectively.
Homeowners should consider checking and replacing filters more often during periods of smoke, dust, or chemical exposure.
Signs your filter may need replacement include:
- Visible dirt or discoloration
- Reduced airflow from vents
- Increased dust inside the home
- Worsening allergy or respiratory symptoms
Continue Following Local Safety Guidance
While improving your indoor air quality is important, homeowners should continue following guidance from Garden Grove city officials and emergency response agencies regarding affected areas and safety precautions.
