6 steps to improve indoor air quality
Spring and summer have a reputation for being allergy seasons, but actually two-thirds of allergy sufferers experience symptoms year-round, according to a study conducted by Isobar. Throughout “closed-window season” the lack of ventilation can cause irritants like dust, pet dander, and mold spores to linger and build up inside homes and offices, causing allergen-related discomfort to flare up. Volatile organic compounds (VOCs) can also build up when fresh air is not circulating and can result in airway irritation as well as other discomforts.
In some areas of the country with warmer climates, pollens can be a constant concern with plants blooming throughout the year. In cooler climate areas, temperature fluctuations can also cause pollen to be present when you least expect it.
"Many people automatically reach for an over-the-counter antihistamine when they experience allergy symptoms due to indoor or outdoor allergens,” says Dr. Bob Geng, a board-certified allergist/immunologist and medical advisor for Honeywell Air Purifiers. “However, by first evaluating your home environment and taking steps to remove or minimize allergens and allergen sources, you can reduce your exposure naturally and may be able to limit the need for medication or allergy shots.”
Reducing indoor allergens
Indoors, irritants can come from numerous sources. Take these steps to reduce allergens and irritants inside your home all year long:
1. Dust and other airborne particles can cling to window treatments, upholstery, throw pillows and other soft items that don’t get vacuumed regularly. Help minimize dust by reducing excessive amounts of fabrics in your home.
2. Wash sheets, pillow covers and mattress covers weekly in hot water of at least 130 degrees Fahrenheit. Frequent laundering in hot water can reduce the presence of dust and dust mite waste.
3. Vacuum carpets at least weekly using a vacuum cleaner with a HEPA filter to remove allergens that can settle deep into the fibers. Vacuuming can stir up, or aerosolize particles, so try to have a non-allergy sufferer do the vacuuming, or wear a disposable dust mask. Run an air purifier to supplement weekly vacuuming and to help capture airborne particles before they settle on surfaces.
4. Three in 10 allergy sufferers have allergic reactions to dogs and cats, according to the Asthma & Allergy Foundation of America (AAFA). Detectable levels of pet dander are present in nearly every U.S. home, even those without pets, as these allergens can easily be carried into the home on clothing and shoes. Limit your pet’s access to bedrooms, and keep them off upholstered furniture.
5. Common household items including soaps, detergents, perfumes, cleaning supplies and building materials like paint and varnishes can emit gases in the form of volatile organic compounds (VOCs). For many, especially for allergy and asthma sufferers with airways that are typically already inflamed, exposure to VOCs can cause nasal passage, lung and throat irritation. The EPA reports that VOC levels inside homes are two to five times higher than levels outdoors.
6. Consider using an air purifier to remove contaminants from the air. Honeywell True HEPA Air Purifiers capture up to 99.97 percent of microscopic airborne particles that pass through the filters, including airborne grass, weed and tree pollens, dust, smoke, pet fur/dander, mold spores, and certain bacteria and virus. Activated carbon pre-filters can also trap common household odors and VOCs.
