Indoor air pollution poses critical, year-round health threat | Photo Credit: Special Arrangement As Delhi, and various other parts in the northern parts of India , brace for severe winter smog, spokespeople for consumer durable makers LG and Dyson said that the air inside homes, too, presents a critical, year-round health threat. Outdoor emissions regularly infiltrate living spaces, combining with domestic activities to create complex, toxic indoor environments.

Citing the 2026 Commission for Air Quality Management (CAQM) analysis, an LG spokesperson said that Delhi’s winter PM2.5 pollution stems from secondary particulates (27%), transport (23%), biomass burning (20%), dust (15%), and industry (9%). Closing doors and windows does not make homes airtight as outdoor pollutants enter through micro-gaps. They then mix with emissions from cooking, incense, candles, volatile organic compounds (VOCs) from paints and furniture, and human respiratory particles.

Alex Hudson, a Dyson engineer, said that indoor air pollution is rarely driven by a single origin as even walking on carpets and sitting on sofas can stir up settled dust particles into breathing zones. The impact extends beyond respiratory irritation as the LG spokesperson highlighted the alarming cognitive toll on children’s brain development.
