Home Air Filters: How They Work and Why They’re Important

Home Air Filters

As a homeowner, your primary goal is to create a comfortable, healthy space you can call your own. There are many ways to achieve this – decor, furniture, appliances, etc. The possibilities are endless…and expensive.

One factor that can end up running up the bill is your energy usage. Luckily, using a high-efficiency air filter is a great way to improve both energy efficiency and overall home comfort, keeping you and your wallet happy. In this article, we will cover how home air filters work and why they’re essential.

How Furnace Filters Work & The Benefits

A furnace filter has a couple of goals, one of which is keeping your AC unit in tip-top condition. The primary job of your air conditioning unit is to circulate the air, cool or warm it up, and then push it out into the various rooms of your home. The air being circulated isn’t always clean and can contain dirt, dust, and other airborne particles. These contaminants will damage your AC unit by creating build-up on the coils. This, in turn, will cause your unit to break down more often, and eventually result in having to purchase a new AC unit altogether.

This is where your furnace filter comes in to save the day.

The furnace filter’s job is to clean the air before it is pulled through the AC blower and circulated through your air ducts. As the dirty air moves through the air filter, the contaminants get trapped, which cleans the circulated air. This keeps your AC coils clean and saves you a lot of time and money in the long run.

On top of that, there are a handful of health benefits to having a high-efficiency furnace filter. Some of which include:

  • Improved cognitive function
  • Decreased risk of airborne illnesses
  • Lower heart rate and blood pressure
  • Improved mental focus
  • Normalized sleeping patterns

Air Filters Are Not a One-Size-Fits-All

In most cases, having an air filter is a win-win; however, air filters are not a one-size-fits-all. For a custom-sized furnace filter that will fit your unit perfectly, click here. If your filter is not sized correctly for your AC unit, the air can bypass the filter altogether. This can mean trouble for you and your AC unit. To save yourself the stress (and the money), please be sure to do your research to find a filter that is both efficient and sized appropriately.


As homeowners, we aim to create a safe and clean environment for ourselves and our guests. High-efficiency air filters allow us to do just that, and can also make homeownership a little less expensive and stressful (which is always a plus). Between the benefits for your AC unit and your health, it seems like a no-brainer to invest in something that will improve your life. Please remember that furnace filters are not a one-size-fits-all and to always do your own research. This will allow your air filter to do its job perfectly and give you the peace of mind that every homeowner deserves.
