Today we Design, Build, Test, and Review this high power shop air cleaner! This video was a year in the making. It's easy to build an air filtration system, but the most important part is how it works. It takes time to fully test something. The end of the video includes a detailed breakdown of how much performance you can expect out of this unit.

A secondary use of this type of filter is to clean the air in public spaces to reduce airborne pathogens. Filters with a MERV 16 or higher rating are capable of filtering 95% of particles between .3 and 1 micron in size. At 2500CFM a this filter unit can process all the air in a small restaurant/shop (1000sq.ft./ 90sq.m) in as little as 3 minutes.

I retested this filter with 2 different fans and got some updated numbers. Check out the new video here:    • Air Filter Updates & The Science of A...
