A:Answer These type of air purifiers are design to process odors that are suspended in the air, not odors that have saturated into furniture, carpet, clothes, etc. Put 1/4" of white vinegar into 3" diameter bowl and it will adsorb smoke odors from furnishings. You will need (1) bowl for every 400 sf. This can take days. If the smoke keeps getting generated, and clothes are not washed in a vinegar / oxyclean solution, you are just fighting a losing battle. The air purifier can cutdown on the smoke odor suspended in the air if ran on high and located near the source.
