2. How MERV 8 filters work

How does the filtration process of MERV 8 filters work?

MERV 8 filters work through a combination of three filtration mechanisms: impaction, interception, and diffusion. When air passes through the filter, larger particles are captured by impaction, which is the process of particles colliding with filter fibers. Smaller particles are intercepted as they try to navigate through the filter fibers. Finally, the smallest particles are captured through diffusion, where they collide with gas molecules and are forced to adhere to the filter fibers.

How effective are MERV 8 filters in removing various particles from the air?

MERV 8 filters are highly effective in removing a wide range of particles from the air. They can capture particles as small as 3 microns, which includes common allergens such as dust mites, pollen, and pet dander.
