Every winter, Delhi is shrouded in its familiar gray smog, and the health effects are visible almost immediately. Despite seasonal action plans and public advice, PM2.5 and PM10 concentrations regularly exceed safe limits. “Exposure to air pollution can cause everything from pneumonia, asthma attacks and COPD to headaches, eye irritation, severe cases of sinusitis and even stroke or heart attack,” says Dr Gurmeet Singh Chhabra, Yatharth Super Specialty Hospital.
Air purifiers have long been marketed as the first line of defense, especially for urban dwellers. ,Dr Sunny Jain, Accord Super Specialty Hospital, says air purifiers can play a vital role in reducing the concentration of indoor pollutants like dust particles, pollen, pet dander, mold spores and other airborne allergens.
However, the debate is in real-world usage. Air purifiers are stationary. “Opening windows or doors can cause the AQI to level off immediately, and the real problem is when you are out of the house at work or jogging in the garden or in the market,” says Dr Sunny Jain.
Many of us spend hours commuting, working in shared offices, and moving between semi-indoor spaces where access to a purifier isn’t always possible. Doctors often stress that purifiers are helpful but not a universal solution, especially when used outside the home.
This is where personal air-cleaning gadgets come in, providing targeted protection in situations where traditional devices fall short.
