   Dust consists of tiny particles like skin cells, hair, and soil. Over time, these particles settle in nooks and crannies. Regular cleaning may not completely eliminate dust in older homes due to intricate architectural features that trap particles. The American College of Allergy, Asthma, and Immunology states that dust mites in accumulated dust can also contribute to allergies and health issues, which may compound the unpleasant smell.

3. Trapped Odors:
   Older fabrics, carpets, and upholstery (often found in antique homes) can absorb and retain odors. These materials can become especially problematic if exposed to smoke, pet dander, or cooking smells over the years. A comprehensive review by M. B. Kull et al. (2019) highlights how textiles can emit odors, particularly when they contain remnants of smoke or mold.

4. Deteriorating Materials:
   As materials in older homes age, they release volatile organic compounds (VOCs), which can contribute to distinct smells. VOCs are emitted from paints, varnishes, and building materials as they break down. The World Health Organization (WHO) states that prolonged exposure to VOCs can have health implications. Older wooden structures may also release odors as they dry out and crack, further adding to the old house smell.

5. Humidity Levels:
   Humidity plays a critical role in exacerbating odors. High humidity levels can promote the growth of mold and mildew, as noted previously. The National Weather Service indicates that relative humidity levels above 60% can contribute to musty odors. Maintaining a balance of humidity is essential for curbing the old house smell and preventing further moisture-related issues.

How Do Air Purifiers Help Eliminate Musty Odors in Old Houses?

Air purifiers help eliminate musty odors in old houses by removing airborne mold spores, dust, and volatile organic compounds (VOCs) that contribute to unpleasant smells. They use filters and technologies to improve indoor air quality effectively.
