Why is activated carbon in the air purifier?

　　Activated carbon is added to the origin of air purification.

　　For many people, the first time they encountered activated charcoal was using a household air purifier. Too many pollutants in the air have caused many people to have allergies and asthma. Therefore, many interested people began to look for quick elimination of these pollutants. Finally, it was found that the adsorption effect of activated carbon was very obvious. It is also because of this that the indoor air purifier was born to help clean the indoor environment.

　　The purification process of activated carbon:

　　Activated carbon was used by humans to remove impurities in water 2000 years ago, and its special absorption properties are loved by everyone. In the early 1980s, powdered forms of activated carbon were commercially available to purify water and remove color from certain sugars. During the First World War, activated charcoal was found to be used in gas masks to protect soldiers. Later, it was found that it could also purify the air and adsorb particulate matter in the air, and thus began to add this process to the air purifier.

　　Why it's called "Activated Carbon":

　　You might be wondering why it's named "activated carbon" and whether it has a non-activated carbon part. The heat used by activated carbon to convert the carbon into an "activated" state causes impurities to be expelled; when used as an air purifier, activated carbon can actively desorb particulate matter in the air. Make the air clean. Note that soot or charcoal is not activated carbon.

　　Activated carbon works in a number of ways, they exhibit a high degree of porosity and extended surface area, which can only mean that it has excellent absorption properties, making it very useful for various filtration methods, where air and water are located. List.

　　The benefits of activated carbon for indoor air purifiers.

　　In indoor air purifiers, activated carbon is often combined with other minerals, such as zeolites. Zeolite can absorb ions and molecules, thereby acting as a filter for odor control, toxin removal, and as a chemical sieve. In some air purifiers, the carbon can be saturated with potassium iodide or mixed with activated alumina to increase the absorption properties. These indoor air purifiers use a combination of chemicals and are especially helpful for sensitive people because they produce compounds that, in addition to absorbing formaldehyde, also remove odors from carpets, wood paneling, and upholstery. Make environmental purification more thorough.
