The Truth About HVAC Filtration

One of the most persistent myths in home comfort is that the more expensive and thicker your HVAC filter is, the better it will be for your system. This widespread misconception is actually causing homeowners to waste money and potentially damage their heating and cooling equipment.

Let’s break down some common filter myths:

Myth #1: The Thicker the Filter, the Better

Actually, using a filter that’s too thick can restrict airflow through your system, forcing your HVAC equipment to work harder. This leads to:
– Higher energy bills
– Increased system wear and tear
– Potential premature system failure

Myth #2: You Only Need to Change Filters Annually

This couldn’t be further from the truth. Most filters need to be changed every 1-3 months, depending on:
– Household size
– Number of pets
– Local air quality
– Filter type

Myth #3: All MERV Ratings Are Suitable for Every System

MERV (Minimum Efficiency Reporting Value) ratings aren’t one-size-fits-all. While higher MERV ratings catch more particles, they may not be appropriate for your specific system. Many residential systems work best with MERV 8-11 filters.

The Bottom Line

The key to proper filtration is finding the right balance between air cleaning efficiency and system performance. Regular maintenance and proper filter selection are crucial for maintaining optimal HVAC performance and indoor air quality.

Remember, consulting with a professional about your specific system’s needs is always the best approach to ensure you’re making the right choices for your home’s comfort and efficiency.
