Maintenance of furnace filters

Regular maintenance of a forced air furnace system includes periodic cleaning or replacement of the furnace filter. Available in several different varieties, the furnace filter was originally designed to protect the furnace and fans from dust, but now is used to remove particles that can affect human health. 19 

In 2009, 52% of Canadian households had a forced air furnace. Most (87%) households that had a furnace reported that they had changed or cleaned the filter in their furnace at least once during the previous year: 43% of households with a furnace changed or cleaned it at least four times in the previous year, another quarter of these households changed or cleaned it every six months, and 19% had changed it once during the previous year. Five percent of households that had a furnace had not changed or cleaned their filter during the previous year, with the remainder indicating they did not know when the filter was changed or cleaned.
