Minimum Efficiency Reporting Values, or MERVs, define the ability of a filter to capture larger particles between 0.3 and 10 microns.
You have an HVAC system in your home, your business, just about anywhere you go. The filters that are part of that system play a huge role in your own air quality and overall health of that space. Regular changing of your filters can increase the quality and efficiency of your systems along with helping in your fight against viruses.
