The furnace (or utility) room is my favourite room in the house. It is the lifeline to your home and it often gets no attention. All the ductwork in your home is like the veins in your body. Cycling air throughout the house is the most important thing. I always say to change your furnace filter every 3 months, and monthly in the winter. It's not a bad idea to get an air purifier for your home as well (preferrably one on each level). | Mike Holmes

Here is how to change your furnace filter. And yes, I do recommend changing it once a month. | Mike Holmes
