Many of the recommendations that I and other indoor air quality professionals make can be very expensive – like installing hardwood or tile floors, or replacing a hot-air heating systems with baseboard or radiator heat. But there are a number of things you can do that won’t cost a fortune and that can help keep the air in your home clean and allergen and irritant free. Below are 15 examples. Read the rest »

If your son or daughter has allergies or asthma, there may be conditions inside the school building that could cause your child to experience health symptoms. What are some of these conditions, and what you can you as a parent do about it?

Carpeting. Many modern school buildings have wall-to-wall carpeting, which is often cleaned in the summer, when weather is most humid. If the carpeting remained damp for more than 48 hours, it may well contain mold growth, subsisting on captured dust. If your child’s classroom smells musty, the carpet may be the culprit. Ask the school to have the carpet dust tested for mold (or contact DACI lab at Johns Hopkins University and find out how to take a sample yourself). Read the rest »

Of all the environmental hazards in houses, lead paint is potentially one of the most serious, because it can and does have the largest number of victims. Lead-poisoned children number in the tens of thousands and suffer from reduced learning skills, behavioral and nervous system disorders, and in the worse cases of poisoning, mental retardation. Lead can also affect unborn children.

Up until 1978, nearly all exterior paints and most interior wood trim paint contained lead pigment. In the Boston area where I live, 80% of the homes contain lead paint, because much of the building stock in the city is older. If you live in an older home, contact your local health department to see what you must do about lead paint. Read the rest »

Soot particles are small enough to be breathed deeply into the lung and even pass directly through capillary walls into the blood stream. The particles may contain carcinogens – such as benzo[a]pyrene – and can also act as “surrogate allergens.” The medical community recognizes that the cornstarch powder in latex gloves (used to keep the rubber from sticking to itself) can acquire latex allergens. When the powdery granules become airborne and are inhaled by someone who has latex allergy, that person can experience an allergic reaction – sometimes severe. Similarly, the microscopic particles of soot that settle on surfaces that contain mold or pet dander can become contaminated with allergenic substances. The particles can then become airborne again and be inhaled when surfaces are cleaned or otherwise disturbed in some way. Read the rest »

Your family is growing in size and you have to find a roomier home. You may feel lucky if the person moving out is leaving behind a refrigerator or some stylish carpeting, but beware. Many things left behind in a house should be cleaned or removed prior to occupancy, especially if you or someone else in your family, particularly a child, has allergies, asthma or other environmental sensitivities.

If you have a child with allergies or asthma, you probably work hard to keep your home and the air inside your home as clean as possible. But there are some things you might do or buy that can actually introduce rather than solve indoor air quality (IAQ) problems.

Let’s start with a hot-air heating and/or central air conditioning system – often a source of many allergens and irritants in a home.

1. Electronic filters are efficient in theory but lose their filtering capacity quite quickly as they get dusty. Since people rarely clean such filters frequently enough (monthly), these expensive filters (often costing upwards to $1,000 each) end up being pretty next to useless – kind of like using gold jewelry as a paperweight.

Your family is growing, and you need more room.

The real estate market is slow, though, so instead of buying a larger home, you may be considering finishing your basement to gain a playroom, office or exercise room.

Maybe that’s your New Year’s Resolution, and you plan to hit Home Depot for your supplies and get started on the project. Read the rest »
