When it comes to air filtration, the MERV rating is an important factor to consider. The acronym stands for Minimum Efficiency Reporting Value, and it is used to measure the effectiveness of a filter in trapping particles. A higher MERV rating indicates a higher level of efficiency in trapping particles, and the highest rating is MERV 16. In a comparative study of MERV 16 filters and HEPA filters, the MERV 16 filters showed improved filter efficiency over time and use as dust-laden filters. This is because the MERV 16 filters are less restrictive and provide higher cabin pressure than HEPA filters.
As a result, they do not need to be replaced as often, which significantly reduces maintenance labor costs. The unique properties of MERV 16 filters also make them more efficient than other types of filters. The filter media removes most of the dirt rather than the particles embedded in the filter, resulting in a higher level of filtration efficiency. In addition, these filters are more effective at trapping small particles than those with lower MERV ratings.
In most cases, a MERV 16 furnace and an AC filter would offer twice the efficiency of a MERV 13 filter at the submicron level. However, since these filters tend to be quite deep compared to traditional filters, they require a dedicated aftermarket housing for installation. MERV 17 to MERV 20 filters are commonly used in operating rooms, cleanrooms, and other settings that require absolute cleanliness. In this case study of comparative analysis, it was concluded that the MERV 16 filters were the optimal choice for both the roof bolter and the front drill due to their improved filter efficiency, greater airflow and cabin pressurization, lower cost, and less frequent replacement than HEPA filters.
