Clearing the Air: The HVAC Filter Myth

As a leading AC repair and HVAC installation company in Oak Park, IL, Berwyn Western often encounters misconceptions about home heating and cooling systems. Today, we’re addressing a persistent myth that has been circulating for years: the belief that using a higher MERV-rated filter will always improve your indoor air quality and HVAC system efficiency.

The Myth

Many homeowners believe that installing the highest MERV-rated filter available will provide the best air filtration and system performance. However, this isn’t always the case, and here’s why:

The Reality

While it’s true that higher MERV-rated filters can capture smaller particles, using a filter with too high a rating for your system can actually cause problems:

• Reduced airflow: Higher-rated filters are denser, which can restrict airflow if your system isn’t designed for them.
• Increased energy consumption: Your HVAC system may work harder to push air through a dense filter, leading to higher energy bills.
• Potential system damage: In extreme cases, using an incompatible filter can strain your system, leading to premature wear and tear.

The Berwyn Western Recommendation

At Berwyn Western, we recommend choosing a filter that balances efficiency and system compatibility. For most residential HVAC systems, a MERV rating between 8 and 11 provides excellent filtration without compromising system performance.

Remember, the best filter for your home depends on your specific HVAC system and indoor air quality needs. If you’re unsure about which filter to use, don’t hesitate to contact Berwyn Western for expert advice tailored to your heating and cooling system.
