I’m just gonna leave this pic up here. That lovely dark grey color is the furnace filter from when I moved into my new place. It looks like the last residents did not change the filter for at least a couple years. Gross. The clean fresh white filter on right is the one that a replaced it with about a week after I moved in. Yes, it took me a week to remember I needed to check the state of the furnace filter. So while I spent my first week unpacking and getting settled, I was also breathing in that nastiness on the left.
I figured this would be a useful post now that the weather has (finally!) cooled down and most of us here in Chicago are turning on the heat. Whether you rent or own, make sure to change the furnace filter! Many renters don’t realize that changing the furnace filter is your responsibility, not the landlords.
So why do you want clean filters?
1. It saves $$$. A clean filter means that the furnace isn’t working as hard to do the same work. This, in turn, leads to a (slightly) lower energy bill, which is good for you pocketbook and the environment. For homeowners, this also helps the furnace last longer so you will have less frequent repair/replacement costs. Worst case scenario: a dirty furnace can start a fire. This is extremely rare but dangerous and disastrous.
2. It can improve your health. It doesn’t take a genius to look at the picture of the two filters and figure out which will provide better air quality in your home. Replacing your filter regularly reduces dust, allergens, mold, bacteria, pollution and a slew of other irritants circulating through your home. This will have the biggest effect on those of you with allergies and/or asthma. Even if you don’t suffer from the previously mentioned A-words, https://elporno.org a dirty filter can lead to more colds, congestion, and eye irritation with all those extra particles floating through the air.
Go check your furnace filter and change it as needed. Furnace filters only cost a few dollars each month and can be purchased at any hardware store. You can buy filters that need to be changed monthly, annually or in-between. I usually buy the three-month filter, but that’s my personal preference.
