    You get to the store to pick something out – and there are so many options you can’t decide. In some cases, you don’t even know what the descriptions mean. One example is with HVAC filters. Each comes labeled with a MERV rating – but do you have any idea what that means, or how it can help you decide the filter that’s right for you? We’ll take a look in this post.

    WHAT IS MERV?

    MERV stands for Minimum Efficiency Reporting Value. The MERV rating ranges from 1-16 and is assigned to HVAC filters. The number represents a scale that measures the filter’s ability to remove particles from the air moving through your system. These particles can be between .3 and 10 microns in size! We’re talking things like dust, pollen, cigar smoke, and some particles you can’t even see. Most home filters have a MERV rating between 7 and 12, while a filter in a place like a hospital is more likely to be rated between 13 and 16. 

    It’s important to know that a HIGHER rating is not necessarily a BETTER rating. What’s important is that the rating of the filter matches the output and the power of your HVAC. The unit and the filter need to work together to create maximum efficiency and comfort for you!

    CHANGING FILTERS

    As with any kind of filter, your air filter needs to be changed occasionally. You need to change filters with higher MERV ratings a bit more frequently. You can change air filters on your own, but it may take some know-how to make sure you get the right one.
