Dust on curtains can have a greater impact on health than many people realize. Curtains act like passive air filters, trapping dust, pet dander, pollen, and even mold spores over time. While this may seem beneficial, these particles can be released back into the air whenever curtains are opened, closed, or disturbed by a breeze from an open window. Once airborne, the allergens can be inhaled, potentially triggering allergies, asthma symptoms, and respiratory irritation. Regular curtain cleaning is an important but often overlooked part of maintaining healthy indoor air quality and creating a cleaner, more comfortable living environment for everyone.
