Everyone wants to breathe clean air in their home, but there’s a persistent myth in the HVAC industry that’s costing homeowners unnecessary money. At Bruton Comfort Control, we often hear from customers who believe that the more expensive the air filter, the better it must be for their HVAC system. Let’s break down why this isn’t always true.
Understanding MERV Ratings
The efficiency of air filters is measured by MERV (Minimum Efficiency Reporting Value) ratings. While higher MERV ratings catch more particles, they can actually cause problems:
- Restricted airflow in systems not designed for high-MERV filters
- Increased energy consumption
- Potential system strain and damage
- Higher utility bills
What You Really Need
For most residential HVAC systems in the Portland metro area, a basic MERV 8-11 filter provides excellent filtration while maintaining proper airflow. These filters effectively capture:
- Dust and debris
- Most pollen
- Common household particles
When Higher MERV Makes Sense
There are specific situations where investing in higher-rated filters might be worthwhile, such as:
- Homes with family members who have severe allergies
- Recently remodeled spaces with excessive dust
- Areas with high pollution levels
The key is finding the right balance between filtration and system performance. For residents in Beaverton, Tigard, Tualatin, Hillsboro, and Aloha, our recommendation is to focus on regular maintenance and proper filter changes rather than spending extra on premium filters that might do more harm than good.
Remember, the most expensive option isn’t always the best solution for your home’s comfort needs.
