At Farley & Hysaw, we often encounter homeowners who believe that purchasing the most expensive HVAC air filters will automatically provide the best air quality for their homes. Today, let’s clear the air about this common misconception.
Understanding MERV Ratings
MERV (Minimum Efficiency Reporting Value) ratings measure how effectively air filters capture particles between 0.3 and 10 microns. While higher MERV ratings (13-20) catch smaller particles, they’re not always the best choice for residential systems.
Here’s why:
• Higher MERV filters can restrict airflow
• Restricted airflow makes your system work harder
• This increased strain can lead to higher energy bills
• Some systems aren’t designed for high-MERV filters
What You Really Need
For most residential HVAC systems, a filter with a MERV rating between 8-11 provides excellent air quality while maintaining proper system efficiency. These filters effectively capture:
1. Dust and pollen
2. Pet dander
3. Most household debris
4. Common allergens
The Bottom Line
Instead of focusing solely on price or MERV ratings, consider what’s best for your specific system. Regular filter changes with the correct type matter more than using expensive, high-MERV filters that might compromise your system’s performance.
Remember: The best filter is one that:
• Fits your system’s specifications
• Gets changed regularly
• Maintains proper airflow
• Provides adequate filtration for your needs
