How Harmful Is Air Purifier For Humans: Air purifiers have become common in every home nowadays. It is claimed that they keep the air clean and protect it from viruses, bacteria and harmful particles. But a new study from America’s University of Colorado has raised serious questions about their use. About 700 studies were reviewed in this research. The surprising thing that came to light was that most of the research was not done on humans, but on empty rooms or animals. That is, there is very little concrete evidence on what effect these air purifiers have on humans in real life.
Less testing on humans, alarm bells
The researchers found that only 8 percent of the studies tested air purifiers on humans. The rest of the research was based on lab rats, guinea pigs or just air samples. In such a situation, it is not clear what effect these devices have on human health in the long run. The study also revealed that some air purifiers can produce dangerous gases like ozone and formaldehyde. Ozone can damage the lungs, increase asthma and also increases the risk of heart-related diseases. Whereas formaldehyde causes irritation in eyes, nose and throat and in large quantities can also cause cancer. In some machines, ozone or ionizer reacts with the chemicals present inside the house and creates more poisonous particles, which are very small and can reach directly into the lungs and blood.
Lack of investigation into real situation
After analyzing 672 studies from 1920 to 2023, it came to light that many new technologies were not tested on humans. For example, there are dozens of studies on some techniques that kill bacteria, but only a limited amount of research has been done on their effects in humans. The researcher says that companies make big claims, but they do not have solid evidence. Before installing these devices in places like schools, hospitals and offices, it is important to prove that they are both safe and effective.
What do experts say?
According to Dr. Yogeshwar Deshmukh, Consultant Pulmonologist, Shaheed Hospital, Durg, “Air purifiers do not directly remove moisture from the air, but if they are continuously run on high setting in a closed room, then the humidity of the room can be reduced. Due to low humidity, there can be irritation in the nose, throat and respiratory tubes. This increases problems like dryness, soreness, cough and irritation in the eyes. It is important to have clean air, but it is also harmful for the lungs.” Along with clean air, it is equally important to have the right humidity.”
What to keep in mind before buying?
Doctors and experts advise to be cautious while buying an air purifier.
- Avoid purifiers that create ozone or work on chemical reactions.
- Purifiers with HEPA filters are considered safer
- Choose the device according to the size of the room
- Periodic cleaning and replacement of filters is necessary
