The Truth About HVAC Air Filters Every Homeowner Should Know

Separating Fact from Fiction in Home Air Filtration

One of the most persistent myths in home comfort is that expensive, high-MERV air filters are always the best choice for your HVAC system. This widespread misconception needs to be addressed to help homeowners make informed decisions about their indoor air quality and system efficiency.

Here’s what you need to know:

The Reality of Air Filter Ratings

• Higher MERV ratings don’t automatically mean better performance
• Some systems aren’t designed to handle thick, dense filters
• Over-filtering can actually reduce system efficiency

Finding the Right Balance

The truth is, your HVAC system needs the right amount of airflow to function properly. Using a filter that’s too restrictive can:

1. Increase energy consumption
2. Reduce system performance
3. Lead to premature wear on components
4. Cause unnecessary strain on your blower motor

Best Practices for Filter Selection

For most residential systems, a MERV rating between 8 and 11 provides excellent filtration while maintaining proper airflow. This range typically removes:

• Dust and pollen
• Pet dander
• Most airborne particles
• Common household allergens

Remember to change your filter regularly – typically every 60-90 days for standard filters, or more frequently for homes with pets or high dust levels.

By understanding these facts about air filtration, you can make better decisions for your HVAC system’s health and your home’s air quality. Don’t fall for the myth that the most expensive filter is always the best choice – choose what’s right for your specific system and needs.
