Air Filtration Systems for Homes, Offices, and Schools
Protecting Our Families from Air Toxics
Air Filtration Systems: A Personal Journey
This topic is near and dear to my heart. When we moved less than 1,000 feet from three major EPA Title V facilities in El Segundo, CA, I never really considered the impact of air toxics. I'm honestly embarrassed it didn't cross my mind, but at the time the location seemed like a charming seaside town.
Our kids were exposed to air toxics at home, daycare, and their public school 24/7, as all these locations were within the same buffer zone. I also worked at the airport while pregnant, where my office was constantly exposed to aircraft exhaust and diesel ground support equipment. When our son's behavior was erratic for years, I often wonder if these prolonged air toxic exposures have worsened the symptoms of his autism, which, while genetic, can be influenced by environmental conditions. It's definitely something that keeps me up at night when I think back on the "would haves" and "should haves."

I am also very aware that not everyone can pick and choose where they live. I grew up near the 91 freeway in Riverside and know many Americans are locked into their locations due to finances and jobs. This is why I wanted to share my lessons learned on how to make your home cleaner and advocate for your children's school to also have cleaner indoor air.
Understanding MERV Ratings
MERV (Minimum Efficiency Reporting Value) ratings measure the effectiveness of air filters at trapping particles. Here's a quick breakdown:
MERV 1-4: Basic filtration, suitable for residential use where minimal filtration is required.
MERV 5-8: Better filtration, commonly used in residential and commercial settings to capture smaller particles like mold spores and pet dander.
MERV 9-12: Enhanced filtration, suitable for homes and offices that require above-average air quality.
MERV 13-16: Superior filtration, often used in hospitals and general surgery settings.
MERV 17-20: Ultra-fine filtration, typically used in cleanrooms and environments requiring the highest level of air purity. ***This is what I recommend for air toxics***
Recommendations for Specific Areas
Near Facilities with Known Air Toxics: If you live near a facility that emits air toxics, consider using filters with a MERV rating of 13 or higher. These filters are effective at capturing smaller particles, including many hazardous air pollutants. However, I believe MERV 17 is the best option for optimal air quality. Be aware that you might face resistance from your school district regarding this choice. Trust me on this.
Fire-Prone States: In areas prone to wildfires, HEPA filters (MERV 17-20) are highly recommended. They can capture fine smoke particles and other pollutants, ensuring better indoor air quality during fire events.
Template Email for School Air Quality Advocacy
Subject: Request for Improved Air Filtration Systems at [School Name]
Dear [Principal's Name],
I hope this message finds you well. I am writing to express my concern about the air quality at [School Name] and to request the installation of advanced air filtration systems to ensure the health and safety of our students and staff.
Given the proximity of our school to [mention any nearby facilities or environmental concerns], it is crucial that we take proactive measures to improve indoor air quality. I recommend installing air filters with a MERV rating of 13 or higher to effectively capture harmful particles and pollutants. A continuous maintenance and replacement of filters will also need to be implemented into the school’s maintenance plan.
I kindly request that this matter be discussed at the next school board meeting. Please find the school board and district supervisor copied on this email for their awareness and support.
Thank you for your attention to this important issue.
Sincerely, [Your Name]
[Your Contact Information]
CC: [School Board Members], [School District Supervisor]
Continuous Maintenance and Replacement of Filters
Regular maintenance and replacement of air filters are essential for optimal performance. Here are some tips:
Inspection: Check filters every 1-3 months, depending on usage and environmental factors.
Replacement: Replace standard 1-inch filters every 90 days, or more frequently if you have pets or allergies.
Cleaning: For reusable filters, follow the manufacturer's instructions for cleaning and ensure they are completely dry before reinstalling.
Conclusion
Ensuring clean air in our homes, offices, and schools is vital for our health and well-being. By understanding MERV ratings, advocating for better air filtration systems, and maintaining our filters, we can significantly improve indoor air quality.
