Types of Furnace Air Filters

Filter Efficiency Ratings

The efficiency of a furnace air filter is typically measured by its Minimum Efficiency Reporting Value (MERV) rating. Higher MERV ratings indicate better filtration performance, capturing smaller particles like allergens, bacteria, and viruses. For residential use, a MERV rating between 8 and 13 is generally recommended for optimal indoor air quality improvement.

Size and Compatibility

Before purchasing a furnace air filter, ensure that it's compatible with your HVAC system. Furnace air filters come in various sizes, and using an incorrect size can affect your system's performance and efficiency. To find the correct size, check your furnace manual or the existing filter's dimensions.

Price and Budget

Furnace air filters are available across a wide price range, with options to suit various budgets.
