Carpets in schools can help the quality of indoor air by trapping contaminants and allergens, says a Cornell University indoor environmental expert.
The findings run counter to growing concerns of some doctors, parents and schools that carpeting might be affecting some children’s health by compromising schools’ indoor air quality (IAQ).
“Concerns that carpeting in schools is contributing to an increase in respiratory problems, allergies and asthma in schools are unfounded,” says Alan Hedge, professor of design and environmental analysis at Cornell. “As long as schools keep floors clean and use high-efficiency microfiltration vacuum bags, carpets can be a healthy, safe and economical floor covering in schools and day-care centers. Microfiltration bags will trap very small particles, such as dust mites and feces, so that these will not become airborne.”
Hedge presented his findings at the annual meeting of the Council of Education Facility Planners, International in Orlando, Fla., recently.
Carpeting, he reports, can improve IAQ because it captures and holds dirt, contaminants and allergens that would otherwise become airborne. These substances are readily and effectively removed by vacuuming with the high-efficiency bags. Synthetic carpets are better than wool, Hedge says, because their fibers’ electrical charges attract potential contaminants.
The best design solution for classrooms, Hedge says, is to combine the strengths and benefits of carpeting for areas under desks and where sitting and teaching activities occur but to use smooth floorings around wet sink areas and boot/shoe storage. But, says Hedge, “Whatever the floor covering, it’s critical that it be kept clean and dry to eliminate any IAQ risks from biological contaminants such as bacteria, fungi and dust mites.”
