Separating Fact from Fiction in HVAC Maintenance

The Myth: Expensive HVAC Filters Are Always Better

Many homeowners believe that the more expensive the HVAC filter, the better it will perform. This misconception leads people to invest in high-end filters with impressive MERV (Minimum Efficiency Reporting Value) ratings, thinking they’re making the best choice for their system and indoor air quality.

The Truth: It’s Not Always About Price

While it’s true that higher-rated filters can capture smaller particles, they’re not always the best option for every HVAC system. Here’s why:

• Restricted airflow: High-MERV filters can restrict airflow, making your system work harder and potentially reducing its lifespan.
• System incompatibility: Some HVAC systems aren’t designed to handle the resistance of high-efficiency filters.
• Overkill for most homes: Unless you have specific health concerns or allergies, a mid-range filter is often sufficient for maintaining good indoor air quality.

What You Should Do Instead

Rather than automatically opting for the most expensive filter, consider these factors:

1. Consult your HVAC manual or a professional to determine the appropriate MERV rating for your system.
2. Change your filters regularly – this is often more important than using a high-end filter.
3. Consider your specific needs, such as allergies or pets, when choosing a filter.
