To address smell and eye irritation in a new home, first identify and eliminate the source. Common causes include mold, mildew, pet dander, or residual construction odors. Improve ventilation by opening windows, using exhaust fans, and running HVAC systems with HEPA filters. Clean surfaces with mild, fragrance-free solutions and address leaks or water damage promptly. Avoid harsh cleaning products and synthetic fragrances. For persistent issues, consider professional air quality testing and remediation.

Eye irritation and smells often stem from poor indoor air quality (IAQ) and chemical vapors. Mold and mildew release spores and mycotoxins that trigger respiratory and ocular discomfort. A 2021 study by the EPA found that homes with IAQ issues reported 30% higher rates of eye irritation and headaches. Construction materials like paints, adhesives, and carpets emit volatile organic compounds (VOCs), which the American Lung Association links to eye redness and throat irritation. Ventilation reduces airborne pollutants by up to 50% (ASHRAE, 2020), while HEPA filters capture 99.97% of particles as small as 0.3 microns. Cleaning with vinegar or baking soda neutralizes odors without triggering allergies. Addressing leaks prevents mold growth, which the JAMA study (2019) correlates with 20% increased asthma risk. Proactive IAQ management, including air purifiers and moisture control, is critical for long-term comfort.
