Furnace air filters come in a range of prices. Many customers ask us, “Does it make a difference whether you buy an expensive filter or a cheaper one?” Honestly, the answer is not a simple yes or no.
When you compare a $4 filter with a $30 filter, it may be tempting to go with the cheap one.
However, air filters are NOT created equal.
Rather than Looking Just at Cost, Evaluate Furnace Air Filters By their Minimum Efficiency Reporting Value (MERV) Rating
MERV grades the efficiency and effectiveness of furnace air filters. Most home filters range between a 1 and 13 rating, with 1 being the lowest rating. 13+ refers to HEPA filters.
When shopping for an air filter, you should be more concerned about checking the MERV ratings than comparing which filter is more expensive than the others. Price does not necessarily equal efficiency when it comes to furnace filters.
Following MERV Furnace Air Filter Ratings Can Make a Difference in the Efficiency of Your Furnace
Studies have shown that air filters with 1-5 MERV ratings minimally protect your HVAC system; these low-efficiency filters offer little pollutant protection.
Filters with high MERV ratings of 7-13 offer significant pollutant reduction. Filters with MERV ratings of 7-13 have even been shown to help individuals with respiratory conditions like asthma.
Choosing the Right Air Filter for Your Furnace Depends on Many Factors
Do you have pets? Do you have asthma or respiratory issues? Do you live in a high pollution / high traffic or high allergen area? If so, don’t skimp on your air filters.
Use air filters with the MERV rating recommended by your HVAC system’s manufacturer and regularly change your filters.
