Air purifiers can sometimes include an Air Quality Index (AQI) display as a feature. The AQI display on an air purifier can provide a real-time reading of the current air quality in the room where the air purifier is located.

The AQI display on an air purifier works by measuring the concentration of pollutants in the air and converting this concentration into a numerical value that corresponds to a specific AQI category. The AQI categories range from “good” to “hazardous,” with each category corresponding to a specific range of AQI values.

Some air purifiers may also include color-coded indicators that correspond to the different AQI categories. For example, a green light may indicate “good” air quality, while a red light may indicate “hazardous” air quality. The AQI display on an air purifier can be a useful tool for monitoring indoor air quality and determining when to turn on or adjust the air purifier.

An air purifier can help to improve the air quality in your home or office by removing pollutants from the air. Air purifiers work by using filters or other technologies to trap pollutants and prevent them from circulating in the air.

Air purifiers can be particularly helpful for people who are sensitive to pollutants or have respiratory problems, such as asthma or COPD. Air purifiers can also be useful in homes with pets, as they can help to remove pet dander and odors.

Overall, the role of an air purifier is to improve indoor air quality and create a healthier living environment for people. However, it’s important to note that air purifiers are not a substitute for good ventilation and other measures to prevent pollution, such as reducing the use of chemicals and avoiding smoking indoors.
