What is the MERV rating of lofted microglass media that is color-coded yellow?

The MERV rating system (Minimum Efficiency Reporting Value) is used to evaluate the effectiveness of air filters in capturing a range of airborne particles. Lofted microglass media is a specific type of filter media known for its enhanced filtration capabilities and is often associated with higher MERV ratings.

Filters made from lofted microglass media that are color-coded yellow typically denote a MERV rating of 14. This classification indicates that the filter is capable of capturing very small particles, providing a higher level of efficiency compared to lower MERV rated filters. Specifically, a MERV 14 filter can effectively capture particles in the 0.3 to 1.0 micron range, including some bacteria and smoke, making it suitable for critical applications where air quality is essential.

This contrast with the other MERV ratings mentioned highlights the advanced filtration capability of the yellow lofted microglass media. Lower MERV ratings, such as 9, 11, and 13, do not achieve the same level of efficiency in particle capture, thus reinforcing the choice of MERV 14 as the correct answer.
