The Hidden Impact of Air Filtration Systems

When it comes to maintaining optimal indoor air quality, understanding MERV ratings is crucial for any homeowner or business looking to improve their HVAC system’s performance. At All-A-Round A/C, Heating & Refrigeration, we believe in educating our customers about these essential technical specifications.

What is a MERV Rating?

MERV (Minimum Efficiency Reporting Value) represents the effectiveness of air filtration systems on a scale of 1-20. The higher the rating, the more efficient the filter is at capturing airborne particles.

Common MERV ratings and their applications:

• MERV 1-4: Basic filtration for residential systems
• MERV 5-8: Better residential and light commercial
• MERV 9-12: Superior residential and commercial
• MERV 13-16: Hospital and general surgery settings
• MERV 17-20: Clean rooms and surgical facilities

Choosing the Right MERV Rating

Most residential HVAC systems work best with filters rated between MERV 8-13. Higher ratings aren’t always better, as they can:

• Restrict airflow
• Increase energy consumption
• Put additional strain on your system

Maintenance Considerations

Regular filter replacement is essential for maintaining system efficiency. Factors affecting replacement frequency include:

• Local air quality
• Household occupancy
• Presence of pets
• Seasonal changes

Remember that selecting the appropriate MERV rating is just one aspect of maintaining optimal indoor air quality. Regular system maintenance and professional inspections ensure your HVAC system operates at peak efficiency throughout the year.
