Filter created to combat toxic drywall gases

A Montreal company has helped create a filter to battle the toxic drywall problem. Aller Air Industries Inc is working with Spiderman Mulholland of U.S. Building Consultants Inc, to find a solution to the harmful gases being emitted from the drywall from China. “We developed a carbon filter unit specifically to reduce the hydrogen sulfide (that has been found to leach from the drywall),” said Aller Air president Sam Teitelbaum. “In a 24-hour test, there was an 85-per-cent reduction.”
