Changing your furnace filter on a regular basis significantly increases the life of your furnace over those that do not have their filters changed regularly. By regular, we mean every 90 days or when it gets visibly covered in dirt. When a filter becomes clogged with dirt, air can’t pass through it very easily and this causes stress throughout the furnace. For a little over $5.00, you can make life easier on your furnace and save yourself a lot of money and headaches. Our 20 x 25 basic filter sells 12 for $64.99, which breaks down to $5.41 per filter. You can’t go to a new release movie for $5.41.

In fact, there’s a lot you can’t do for $5.41 that aren’t nearly as important as ensuring a long life for your furnace. You can’t park for the day in a Lodo garage. You can’t buy a beer at a Broncos game. Or a Rockies game. Or even a Nuggets game. Really, Nuggets? You can’t order a typical combo meal, which are generally in the $7 -$8 range. You can’t go bowling. Right now, you may be able to buy two gallons of gas, but you can’t buy three. Your furnace filter will definitely outlast the two gallons of gas you buy.

Clearly, your furnace filter is the best money you are going to spend, coming in at just over $5 each, when so many less important things cost more money. Plus, it’s the best use of your time, as it only takes a couple minutes to change out your filter.
