The Truth About HVAC Air Filters: More Expensive Doesn’t Always Mean Better

Common Misconceptions in Home Air Filtration

One of the most persistent myths in the HVAC industry is that the most expensive air filters are always the best choice for your home’s heating and cooling system. At Nuccio Heating & Air Conditioning, Inc., we regularly encounter homeowners who believe they’re doing their system a favor by installing the highest-rated, premium-priced filters.

Let’s clear the air about this common misconception.

Understanding MERV Ratings

MERV (Minimum Efficiency Reporting Value) ratings indicate how effectively an air filter captures particles passing through it. While it might seem logical that the highest MERV rating (16-20) would be ideal, this isn’t always the case for residential systems.

Here’s why:

• Higher MERV filters are denser and restrict airflow
• Restricted airflow makes your system work harder
• Increased strain can lead to higher energy bills
• System performance may actually decrease

What You Really Need

For most residential HVAC systems, a filter with a MERV rating between 8 and 13 provides excellent air filtration while maintaining proper airflow. These mid-range filters effectively capture:

• Dust and pollen
• Pet dander
• Mold spores
• Most airborne particles

Remember, the best filter for your system is one that balances air quality with system efficiency. If you’re unsure about which filter type is right for your HVAC system, consulting with a professional technician can help you make the best choice for your home’s specific needs.

Regular maintenance and proper filter selection are key to maintaining optimal indoor air quality and system performance. Don’t fall for the myth that the most expensive option is always the best choice for your home.
