1. Plant elimination method (spider plant, aloe vera) Spider plant, aloe vera, and tiger tail can absorb a large amount of indoor formaldehyde and other pollutants to eliminate and prevent indoor air pollution; The fungicides secreted by flowers such as jasmine, lilac, honeysuckle, and morning glory can kill certain bacteria in the air, inhibit the growth of tuberculosis, dysentery pathogens and typhoid bacteria, and make the indoor air clean and hygienic. Most plants photosynthesize during the day, absorbing carbon dioxide and releasing oxygen; It breathes at night, absorbs oxygen and releases carbon dioxide. Some plants are the opposite, such as cacti release carbon dioxide during the day, and absorb carbon dioxide at night to release oxygen, so that at night there is a cactus in the room, which can replenish oxygen and facilitate sleep.

2. Adsorption method (activated carbon) Adsorption is a solid surface phenomenon. It is the use of porous solid adsorbents to treat gaseous pollutants, so that one or several of the components are adsorbed on the surface of the solid adsorbent under the action of molecular gravity or chemical bonding force, so as to achieve the purpose of separation. Commonly used solid adsorbents are coke and activated carbon, among which activated carbon is the most widely used.

Activated carbon has adsorption function for benzene, toluene, xylene, ethanol, ether, kerosene, gasoline, styrene, vinyl chloride and other substances.
