Got 1 year of solid use and still another year of it performing around 60 percent. Great lil filter.
February 4, 2018
Odor elimination lasted about 12-14 months removed the endcaps and switched them around and odor reduction lasted another 6 months, I put the filter in a metal barel and lit a hot coal fire under it, it released a ton of smell and was good for yet an additional 6 months using both sides, on daily use in dusty conditions. After over 2 years i could not recharge it by heating it above 500 degrees. Ordered again, so far zero odor, running 24/7. Make sure you shake it out and its not pointing in the direction of anything white,as some fine carbon dust shoots out the fan for first minute or so which happens with most of these type of filters. Works best with an inline fan, the white cloth dust cover it come with helps preserve the carbon's life so use it.
