Air quality has become a major concern during winter, making air purifiers the only go-to option. But is it true that overusing these purifiers can irritate the lungs? We wanted insight from experts, and Dr Suleiman Ladhani, a consultant pulmonologist at Wockhardt Hospitals, Mumbai Central, concurred that it can. “While air purifiers don’t remove moisture directly, running them continuously on high settings in a closed room reduces indoor humidity. Low humidity can irritate the nose, throat, and airway lining. This may lead to dryness, scratchiness, coughing, and burning eyes. Clean air matters, but what your lungs really prefer is clean air with healthy moisture levels,” said Dr Ladhani.
So, if purifiers reduce humidity, should people limit their use?
Dr Ladhani said purifiers remain pertinent during high-AQI days, especially for children, seniors, and anyone with asthma or allergies.
“The solution isn’t to stop using them; it’s to use them wisely. Switch to auto mode, run them for a few hours at a time, and avoid long stretches in fully sealed rooms to prevent dryness. Pairing purifiers with a humidifier, a bowl of water, or even a damp towel can help restore balance. Ideally, indoor humidity should stay between 40 and 60 per cent,” said Dr Ladhani.
How can someone tell if their indoor air is too dry?
Dr Ladhani shared signs include persistent throat irritation, morning nosebleeds, dry cough, flaky skin, and a scratchy sensation in the upper airways. “Many people blame pollution alone for these symptoms, but very dry indoor air is often an overlooked factor,” said Dr Ladhani.

What small changes make indoor air healthier during high-pollution periods?
*Use purifiers in moderation; avoid keeping them on turbo nonstop.
*Add moisture: humidifiers, bowls of water, or wet towels can help.
*Keep nasal passages healthy with saline sprays.
*Ventilate during low-pollution windows, usually early mornings.
*Seal windows and doors during peak AQI hours.
*Check and replace purifier filters regularly; clogged filters reduce efficiency and strain airflow.
What to note?
Plants don’t replace purifiers or proper ventilation, but they can add some humidity and create a more comfortable indoor environment. They’re best seen as a helpful addition, not the main solution, said Dr Ladhani.
Your home can remain a safer breathing space even when outdoor air quality drops. “The key is balance: combine purification with proper humidity. Clean air is good; clean, comfortably moist air is far better, contended Dr Ladhani.
