The Truth About Your Home’s Air Filtration
One of the most persistent myths in home heating maintenance is that you should always opt for the highest-rated MERV filter available for your furnace system. This misconception is not only false but could be causing damage to your HVAC system and increasing your energy bills.
Let’s break down the most common filter-related myths:
Myth #1: The Higher the MERV Rating, the Better
Higher-rated filters can actually restrict airflow too much for many residential systems. This makes your furnace work harder, potentially leading to premature system failure and increased energy consumption.
Myth #2: You Only Need to Change Filters Once a Year
This dangerous myth can lead to:
• Reduced system efficiency
• Poor indoor air quality
• Higher energy bills
• Increased wear on your furnace
Myth #3: All Filters Are Created Equal
The truth is that filter quality varies significantly between manufacturers and types. The right filter depends on your:
• Specific furnace model
• Home’s air quality needs
• Local environmental conditions
The Reality
For most residential systems, a MERV rating between 8-11 provides excellent filtration without compromising system performance. Filters should typically be changed every 2-3 months, more frequently if you have pets or live in dusty conditions.
Remember, proper filter maintenance is just one component of a well-maintained HVAC system. Regular professional maintenance ensures your system operates efficiently and extends its lifespan.
By understanding these truths about furnace filters, you can make informed decisions that protect both your system and your wallet while maintaining healthy indoor air quality throughout the Treasure Valley area.
