If the indigenous method of absorbing the smell of cigarettes does not prove effective, it may be worthwhile to try an air purifier. However, the CDC warns that although "eliminating smoking indoors can completely protect non-smokers from second-hand smoke", there is no air purifier or traditional ventilation system that can completely eliminate non-smokers from second-hand smoke. Therefore, although it is obvious that the only way to completely get rid of secondhand smoke exposure is to completely ban smoking indoors, the use of air purifier mini may at least help reduce the adverse health effects and reduce unpleasant odors.

　　The carbon filter is the most commonly used filter for gas removal. They are designed to capture the gas as it passes through the activated carbon bed. It contains tiny pores to increase its surface area, thereby creating more positions on the filter to capture VOCs in the smoke. The gas attaches to the carbon filter through a process called adsorption, which allows gaseous pollutants to attach to the outside of the carbon. If you plan to use a carbon filter, the Environmental Protection Agency recommends that it contains a lot of carbon to improve efficiency.

　　Another warning is that the carbon filter must be replaced frequently. Replacing the filter in accordance with the manufacturer's guidelines is a good standard, but if you have any questions or smell toxic gases, replace it immediately. Please note that although carbon filters can help deal with smoke odors, tobacco smoke can fall and penetrate most surfaces, making it difficult to completely and continuously remove the odors. Finally, to know that a carbon filter cannot remove dangerous carbon monoxide, you should have a separate carbon monoxide detector in your home.
