Many homeowners believe that purchasing the most expensive, highest-rated HVAC air filters will automatically result in cleaner indoor air and better system performance. At Nuccio Heating & Air Conditioning, Inc., we’re here to debunk this common misconception.

Understanding MERV Ratings

MERV (Minimum Efficiency Reporting Value) ratings range from 1-20, with higher numbers indicating finer filtration. However, here’s why the highest rating isn’t always the best choice:

• Higher-rated filters can restrict airflow
• Restricted airflow makes your system work harder
• Excessive strain leads to higher energy bills
• System performance may actually decrease

Finding the Right Balance

Most residential HVAC systems are designed to work optimally with filters rated MERV 8-13. These filters effectively trap:
• Dust and debris
• Most allergens
• Common household particles

The Cost-Effective Solution

Instead of focusing solely on MERV ratings, consider these factors:
• Your specific indoor air quality needs
• Your HVAC system’s specifications
• Regular filter maintenance schedule

Remember, the key to maintaining optimal indoor air quality isn’t just about buying the most expensive filter – it’s about choosing the right filter and maintaining it properly. Regular filter changes with appropriate MERV ratings will keep your system running efficiently while protecting your indoor air quality.
