Merv efficiency rating
WebMERV (Minimum Efficiency Reporting Value) is a standard that rates the overall effectiveness of air filters. A high MERV rating means a finer filter, which removes more airborne contaminants. The average home air system can remove airborne contaminants with a filter rated between MERV 6 – 13. Web7 apr. 2024 · MERV-16: HEPA vs High Efficiency Air Filters: As a quick side-note to summarize these filters, there are many people throughout the industry that call these higher MERV filters “HEPA” filters – and they are not. HEPAs are tested under a completely different test method, are typically a different size (24x24x11.50 exact vs 24x24x12 …

Web12 dec. 2024 · The difference between the MERV and MPR systems is that the MERV system uses a scale of 1-16, while MPR uses a scale of 100-2800. The MERV system rates air filters on their ability to capture 3 different sizes of particles. The MPR system is focused on measuring a filter’s effectiveness at capturing the tiniest particles – E1 particles.
