Airpura T600DLX Heavy Tobacco Smoke and Cigar Smoke.
This filter cleans the air pretty good if left on high speed for en extended period. I smoke cigars in my shop for which I bought this filter for. I anticipated a higher air flow out of the filter as currently not much is coming out even set on high. I took the bottom of the filter off to see if there was plastic around the carbon filter but found none so this may be just the way it is and the carbon filter is very restrictive. Based on the claim of cleaning 2,000 sq. Ft. One would think there would be a higher flow. My shop is 800 sq. Ft.
I should mention also that there is a substantial amount of noise when set on high, enough that it is difficult to understand conversation. Other than that if left on high overnight the air is clean of odor the next morning.
