Health Officials Urge Winter Ventilation Checks

King County health officials are reminding residents to check their home ventilation systems as winter approaches.

Seasonal Concerns

With homes sealed tight for heating efficiency, indoor air quality can deteriorate rapidly without proper ventilation. Carbon monoxide risks also increase when furnaces run continuously.

Free CO detector programs are available through local fire departments for qualifying households.

Simple Steps

Test existing CO detectors monthly and replace batteries annually. Schedule furnace inspection before heavy use season begins. Consider adding a CO2 monitor to track ventilation adequacy.
