Why Does My Home’s Air Filter Get Dirty So Quickly?

Does it feel like you just replaced your home’s air filter yesterday, yet you find yourself changing your air filter once again? Why is this happening?

There are many factors that play into how often you should change your air filter and why your home’s air filter is getting dirty so quickly.

Top Factors:

  • The type of air filter you’re using.
  • You have pets in your home.
  • You have leaky air ducts.

Type of air filter you’re using

1 inch pleated air filters are one of the most common air filters used, and if you do use this, you may be finding yourself having to change your air filter much more often. 1 inch pleated filters get dirty quickly because they’re as fine as a fish net with very small gaps. These filters catch everything small and big, but that also means they fill up faster. Consider switching to a disposable fiberglass filter, thicker pleated filter, electrostatic, or HEPA filter.

Pleated filters are made from polyester or paper material and come in a variety of widths from 1 to 6 inches thick. Consider choosing a pleated filter with a higher thickness level.

Fiberglass filters are typically 1” thick and made from spun fiberglass. Fiberglass filters typically need to be replaced about once a month.

Electrostatic filters technically never need to be replaced because they can be washed. These filters trap air contaminants between positively and negatively charged materials. It is recommended that you vacuum or wash electrostatic filters at least once a month.

HEPA filters are used in most home air purifying systems and should be replaced every 12-18 months.

You have pets

Furry pets can quickly clog up your air filter with hair, dirt and pet dander.

You have leaky air ducts

Leaks in your air ducts can introduce dust and dirt from your attic. The more dirt brought in by your leaky air ducts, the more dirt your air filter accumulates.
