Common HVAC Filter Myths That Could Be Costing You Money


The Truth About HVAC Air Filters: Separating Fact from Fiction

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 heating system and air quality. Let’s dive into why this common belief isn’t always accurate.

Myth: Thicker Filters Are Always Better

Many homeowners believe that purchasing the thickest, highest-MERV-rated filter will provide the best protection for their HVAC system. However, this isn’t necessarily true. Here’s why:

• Too-thick filters can restrict airflow
• Reduced airflow makes your system work harder
• Higher energy bills often result from restricted air movement
• System strain can lead to premature equipment failure

The Real Story

The truth is that you should choose a filter that:

1. Matches your system’s specifications
2. Provides adequate filtration for your needs
3. Allows proper airflow
4. Gets changed regularly according to manufacturer recommendations

What You Should Do

Instead of automatically choosing the most expensive filter, consider:

• Consulting your HVAC manual
• Following manufacturer guidelines
• Changing filters monthly during heavy use
• Monitoring system performance

Regular maintenance and proper filter selection are key to maintaining your heating system’s efficiency. When in doubt, it’s always best to consult with qualified HVAC professionals who can recommend the right filtration solution for your specific system and needs.

Bottom Line

Don’t fall for the myth that the most expensive filter is automatically the best choice. The right filter for your system will balance filtration with proper airflow, ensuring optimal performance and efficiency for your heating system throughout the year.

Remember to schedule regular maintenance checks to ensure your system operates at peak efficiency, regardless of which filter you choose.
