Pleated Air Filter: 20 x 25 x 1", MERV 7, 71% Efficiency MPN:118-701-004

Air filters play an essential role in maintaining air quality inside buildings and machines by capturing particulate matter such as dust, allergens, or pollen from the air. Pleated filters provide high efficiency even on larger particles due to their structure, which increases the surface area available for trapping particles. This filter measures 20 x 25 x 1 in and has a MERV rating of 7, meaning it can capture efficiently most of the large particles while still allowing some airflow through. Its high efficiency provides an ideal option for areas that require clean environments where air quality needs to be controlled, commonly seen in medical facilities or commercial buildings; also, these filters are designed to withstand repeated cleaning so that they're environmentally friendly, reusable, and cost-efficient in the long run.
