To see just how much air pollution we may be exposed to in our homes, Rabinovitch conducted a study in which he asked school children to carry air monitors with them for several weeks. Twenty-four hours a day, seven days a week, those monitors collected air samples in the children's homes and as they walked to and from school.

"For many of these kids, the amount of air pollution that they were being exposed to was often higher inside the home than outside the home," he said.
That doesn't surprise Hope Duncan. Her 13-year-old son, Jack, suffered a near-fatal asthma attack in 2008, and since then, Duncan says she has learned a lot about triggers that are hidden around her home.
"They can be anywhere," said Duncan. "You never know what's underneath the carpet that has accumulated from pets or from water damage. There may be things in the couch or behind the walls that you simply don't know about," she said.

"He spends most of his time in his room, and at least nine hours a night sleeping in there," said Duncan. "After spending the day outside, collecting all these allergens in his hair and on his body, we just want to make
