A more expensive HVAC filter isn’t automatically a better filter for your system.
Filters with very high filtration ratings can catch smaller particles but they can also restrict airflow if your HVAC system wasn’t designed for them.
And restricted airflow can lead to:
• Longer run times
• Higher energy use
• Less comfortable rooms
• Extra strain on your blower motor
• Frozen AC coils
The goal isn’t to buy the filter with the biggest number on the package.
The goal is to use the right filter for your system and change it before it becomes clogged.
