MERV. What does it mean? Why is it important? You may have noticed this word as you searched for new filters for your furnace, but if you don’t understand what it means and why it’s important chances are, your home’s heating system won’t be working up to its full potential this winter.
Let’s start with the basics - what does MERV mean? It stands for Minimum Efficiency Reporting Value which in plain English means “how effective is this air filter?”
MERV Ratings Explained
The scaled used to rate air filters when it comes to the MERV system ranges from 1-16. The higher the rating, the fewer dust particles and other airborne contaminants can get through, though higher ratings don’t always mean the filter is better. Filters are commonly tested for things like pollen, dust mites, mold spores, pet dander and tobacco smoke.
Since filters with high ratings make it more difficult for particles to pass through, airborne pollutants tend to build up on the filter more frequently. As a result, they require more frequent maintenance - whether it’s changing or replacing the filter completely. Neglecting your furnace filters can cause your system to work much harder than it has to and can potentially lead to severe damage.
