Maintaining The AC Air Filter

If you live in a house or apartment with a central air conditioning system, or even drive a car, you’ve probably had to change an air filter at some point. Air filters help trap dust and other allergens from being circulated back into your home’s breathable air.

Let’s take a look at how air filters function and how you can keep your air filter doing its job for as long as possible.

How an Air Filter Works

Air filters, being simple, actually do quite a lot. They are usually made of spun fiberglass installed between a cardboard frame. They keep your air cleaner by filtering by trapping allergens and particles that work their way into your house. These particles include:

  • Pollen
  • Dust
  • Bacteria
  • Mold spores
  • Animal fur

You need to change the air filter as often as possible because it actively cleans the air anytime the AC unit is running. This ensures that your breath remains free of mold particles and other harmful things.

Maintaining The Air Filter

Clogged air filters not only let allergens and other particles stay in your house’s air, but it also limits the free airflow from your AC unit. This can, for sure, raise energy bills and cut down the unit’s efficiency. 

Maintaining the air filter is as simple as cleaning or changing it. An AC air filter should be checked at least every month and either replaced or cleaned. The simple way to check the filter is to hold it up to the light if you cannot see the light passing through the filter, it means it’s time for a new one. 

Common Air Filter Problems

There is a row of issues that can occur due to a clogged air filter. If you notice frozen evaporator coils or your unit is not cooling as good as it should, all this may be caused by a dirty filter that just needs to be replaced. 

Understanding your AC equipment can help you identify potential problems early on, saving you time and money later.
