In recent days, many regions have been suffering from severe smog, and with the rise of haze, various "clever" tips have started circulating online. One such trend has gained attention: using the filter plug from a cigarette as a nasal filter to block PM1.6 or larger particles. The claim is that inserting the filter into the nostrils can help reduce the effects of smog.
However, according to experts, the primary purpose of a cigarette filter is to trap harmful substances like tar during smoking, not to filter out fine particulate matter such as PM2.5 or PM1.6. This misconception has sparked a wave of online discussions and experiments.
Some netizens have shared their experiences, claiming that by removing the paper wrapping from two cigarette filters and inserting them into the nose, they were able to breathe more comfortably in smoggy conditions. They even posted photos of themselves doing so, saying that it helped reduce the smell of smoke and made breathing easier.
Despite these claims, respiratory specialists warn that this method may not be safe. Dr. Liu Yi, a senior physician at the Air Force General Hospital, pointed out that inserting the filter into the nose increases air resistance, making it harder to breathe. Many who tried it reported that it wasn’t as smooth as claimed, and some even found the taste of tobacco unpleasant.
Moreover, after testing, some users noticed that the filter material had a slight chemical odor and could irritate non-smokers. Additionally, there are concerns about the long-term effects of inhaling tiny fibers from the filter, which could potentially harm the lungs.
According to research, most cigarette filters are made of cellulose acetate or polypropylene, which are generally considered non-toxic. However, for people with allergies, these materials might cause adverse reactions. Experts also emphasize that cigarette filters are not designed to block PM2.5 or smaller particles, and using them as nasal plugs is not a recommended solution.
Dr. Liu added that relying on such methods could be dangerous, as it may interfere with normal breathing and expose individuals to unknown risks. He advised people to use proper face masks instead of makeshift solutions when dealing with smog.
As the haze continues, it’s important to rely on verified information and professional advice rather than untested online trends. Stay safe and protect your health.
