It absorbs smoke particles in the HEPA filter under anion mode. Then, the 3 Filtration Stage True HEPA filter will filter all smokes out of fresh air. So yes, it removes the smell of smoke by catching all smoke chemicals from the air.
HEPA stands for High-Efficiency Particulate Air. HEPA filters, originally designed by the U.S. Army to remove radioactive materials from the air, are the most effective way to remove pollen, dust, and other indoor particle pollutants. A True HEPA filter can remove 99.97% of airborne particles 0.3 microns or larger-- that's 166 times smaller than a human hair. Sometimes, you may see some filters named HEPA-like or HEPA-style, or HEPA-type. Unlike true HEPA filters, these filters cannot actually remove 99.97% of bacteria down to 0.3 microns in diameter.
Generally speaking, the higher the HEPA filter grade, the better the purification effect. True HEPA filters usually range from H10-H12. And the highest grade of HEPA filter is H13-H14, which is considered to be medical grade. A normal HEPA filter (H10-H12) removes 99.97% of particles that are 0.3 microns or larger while a medical grade HEPA filter removes 99.97% of particles that are 0.1 microns or larger.

In the third and final stage of filtration, we add an activated carbon filter that helps to remove bad smells from your home. The large pores in the activated carbon are not effective in removing large particles, but they are exceptionally great at trapping odor-causing molecules so that your house smells fresh at all times. For some tough and strong odors, we would strongly recommend you to try ozone generators to do thorough sterilizing and odor removal.
