Common HVAC Filter Myths That Cost You Money


The Truth About Air Filters Your HVAC System Really Needs

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

Let’s break down the reality:

The High MERV Myth

Many people believe that purchasing the highest MERV (Minimum Efficiency Reporting Value) rated filter will provide the best air quality for their home. However, unless your HVAC system was specifically designed for high-MERV filters, using one can actually:

• Restrict airflow
• Make your system work harder
• Increase energy costs
• Potentially cause system failure

The Real Solution

Instead of focusing solely on MERV ratings, consider these facts:

1. Most residential HVAC systems work best with filters rated MERV 8-11
2. Change your filter regularly (every 1-3 months)
3. Consult with professionals about the right filter for your specific system

Cost-Effective Alternatives

If you’re concerned about air quality, consider:

• Regular system maintenance
• Standalone air purifiers for specific rooms
• Proper ventilation
• Regular duct cleaning

Remember, the most expensive filter isn’t always the best choice. The key is finding the right balance between filtration and system efficiency. When in doubt, consult with HVAC professionals who can recommend the perfect filter for your specific system and needs.

Protecting your HVAC investment doesn’t have to break the bank. By understanding these filter facts, you can maintain optimal system performance while ensuring healthy indoor air quality for your family.
