Why your room stays dusty even with windows shut

Closed windows don't keep a room dust-free, says Deepak Kumar H, CEO of Papillon Interiors, because much indoor dust is generated at home. Walking, sitting or changing bedsheets releases particles. Curtains, sofas, mattresses, carpets and cushions constantly shed textile fibres that mix with skin flakes, hair and outdoor particles, which is why beds are a major source.
