The Hidden Impact of Air Filtration on Your HVAC System

When it comes to maintaining your home’s heating system, one of the most overlooked yet crucial components is the air filter’s MERV rating. At Riley Heating & Cooling, we often find that homeowners in the Melrose Park and Oak Park areas are surprised to learn about the significant impact proper filtration has on both air quality and system efficiency.

What is a MERV Rating?

MERV (Minimum Efficiency Reporting Value) ranges from 1 to 20, with higher numbers indicating better filtration. Here’s what you need to know:

• MERV 1-4: Basic filtration for large particles
• MERV 5-8: Common residential filters
• MERV 9-12: Superior residential filtration
• MERV 13-16: Hospital-grade filtration
• MERV 17-20: Clean room and surgical settings

Finding the Right Balance

For most homes in Elmhurst and River Forest, we recommend MERV ratings between 8 and 13. Higher isn’t always better – too high of a MERV rating can restrict airflow and force your furnace to work harder, potentially leading to premature wear and increased energy costs.

Regular Maintenance Matters

No matter which MERV rating you choose, regular filter changes are essential. For optimal performance in the Elmwood Park and Forest Park areas, we recommend checking filters monthly during peak heating season and replacing them at least every three months.

Remember, proper filtration not only protects your heating system but also contributes to healthier indoor air quality for your family. Contact Riley Heating & Cooling today for professional guidance on selecting the right filtration solution for your home’s specific needs.
