This past weekend my husband and I changed out our furnace filter. The previous owner of our home had been using a space heater in one room of the home and leaving the heat otherwise completely off (which is unheard of in the Midwest). We know our vents will be full of ick as the season wares on, so the idea of a filter whistle looks like it's right up our alley! Over at the home repair and DIY blog Charles & Hudson, they shared a great tip to save a little green this winter as you start to kick those furnaces on. Instead of checking on your filter as the months go by, let it tell you when it needs to be changed by installing a Filter Whistle.
If your furnace is working harder than it should, chances are you'll be paying more for the experience. Never having used one of these little gizmos before we're can't give you tested results ourselves, but for less than $2, we're willing to take the charge. The whistle clips into your filter and goes off when it's 50% clogged, letting you know it's time for a new one. Check out more over at Charles & Hudson and the AM Conservation Group
