We tend to forget about changing the filter, although we should do it! It is the job of the furnace to keep the living room warm, but nobody cares about its needs. Nonetheless, a dirty filter will make it work harder, which will lead to higher utility costs.

First of all, set an alarm on your phone or wall calendar. Personally, I prefer the first Saturday morning of every month.

When the alert rings, go directly to the basement or utility closet. Locate that part of your furnace where the air is sucked and remove the old filter. See the number indicated on the cardboard frame of the filter – it will help you to buy the right size. There will probably be something like 16x25x1 or a similar designation.

However, if you are unable to identify the right filter yourself, you can always take the old one to Home Depot or Lowe’s. Employees there will help you to figure out your number easily enough. In addition, there are plenty of filters available for your choosing, but personally, I prefer mid-price pleated filters. They efficiently catch dust particles and save me money.

Indeed, this five-minute procedure will protect your house from being cold in January. It will also allow you to avoid paying big amounts of money for utilities. Clean air is an additional bonus. 😊

It might be useful for you to write down the number of your filter and put a note on your furnace. Consequently, installation of a new filter will be a breeze – just plug it in with the arrow directed towards the blower.
