House Dust
House dust contains a potent mixture of dirt and allergens , from dust mites and mold to animal dander and insects . Breathing dust particles can irritate inflamed airways , as well as set off allergic reactions .
Dust mites are tiny insects , not visible to the naked eye . They require two things to live : human dander ( the skin flakes that people naturally shed ) and moisture . Dust mites live in mattresses , pillows , carpets , bed covers , and upholstered furniture , and their allergens easily settle in furnishings and house dust .
How can you control dust mites ?
• Vacuum regularly with a HEPA ( high-efficiency particulate air ) - filtered vacuum .
• Cover mattresses and pillows with special dust-mite-proof encasings , to keep allergens out of your airways while sleeping .
• Wash bed linens , sheets , and covers every week in hot water ( at least 130 ° F ).
• If possible , get rid of carpets , extra pillows , and upholstered furniture , especially in your bedroom .
• Limit stuffed animals in children ’ s rooms ; use only those that can be washed weekly in hot water ( at least 130 ° F ).
• Dust often .
• Keep humidity levels in your home below 50 %; use a dehumidifier in damp areas , such as basements .
Molds
Molds can be found almost anywhere that moisture and oxygen are present . They live both indoors and outdoors . The key to managing molds indoors is to reduce moisture throughout your home .
• Keep humidity at less than 50 % to discourage mold growth . If needed , use a dehumidifier , especially in basements .
• Repair water leaks wherever they occur , such as around pipes or in the walls or ceilings . Watch out for mold in areas where water is normally present , such as around and under sinks and in bathtubs and showers .
• If mold is visible on a surface , clean it with fungicide or a bleach and water solution .
