Air purifiers have become increasingly popular in recent years, as people have become more aware of the importance of indoor air quality. However, there is some debate about whether or not air purifiers can be harmful.
One of the main concerns about air purifiers is that they can produce ozone, which is a harmful pollutant. Ozone can irritate the lungs and cause respiratory problems, especially in children and people with asthma. Some air purifiers also produce other harmful chemicals, such as formaldehyde and benzene.
