The filtering efficiency is even higher for particles larger or smaller than 0.3 microns. An air filter’s minimum efficiency reporting value (MERV) rating measures how effectively the filter stops dust and other contaminants from passing through the filter and into the air stream. MERV stands for Minimum Efficiency Reporting Value. MERV means Minimum Efficiency Reporting Value. What Is An Air Conditioner Filter? If your HVAC system does not support MERV or HEPA filter upgrade, get a HEPA air purifier for every room and turn it on with at least 2 air changes per hour. HEPAs are tested under a completely different test method, are typically a different size (24x24x11.50 exact vs 24x24x12 nominal) and HEPA filters are also defined by IEST standards. Evidently, not all filters are created equal, and if you seek efficiency in the system you acquire, continue to read to first understand how two on the most common filter types work and differ, more precisely MERV filters and HEPA filters.
