Why is Changing my Air Filter so Important?

I don’t know about you, but when it comes to changing my air filter, I tend to dig in my heels and resist. I really don’t know why. It makes no sense. They are not hard to change. They do not cost much money. They make the air I breathe better. And they keep my air conditioner working at its best.

It is August and my air conditioner is running pretty much all day long. In Houston it is HOT, and it is HUMID. The idea of my air conditioner breaking is more of a nightmare than a bad dream. One of the easiest and best things you can do to keep your air conditioner working is to change the air filters. A clogged air filter can cause extensive damage to your system. Thus, if you check your air filter’s condition regularly, you ensure the longevity of your system — saving yourself thousands in possible repair and replacement costs.

Even if my air filter does not lead to a complete breakdown and service call, it does reduce the efficiency of my system. When your air filter is clogged it acts as a barricade preventing the flow of air from the room, to the air conditioner, and back out into the room. This will cause your system to work overtime drawing air in and pushing it back out to keep your home cool. This extra work will show up in your utility bills.

Most important, changing your air filters improves the respiratory health of the family. Allergies and asthma are an issue in my family, especially for my husband. A clean air filter means you are not constantly circulating dust, dust mites, pollen, bacteria, mold, and other small particles in the air that contribute to allergies, asthma, and other chronic respiratory issues. Instead, your system will be able to purify the air, leaving it clean and healthy for your entire family.

So, why when my husband asks me to buy air filters, do I resist spending that $12-$20 extra dollars at the grocery store? I will try really hard not to anymore.
