Why Change Your Air Filter?

By February 5, 2019November 29th, 2020No Comments

Have you ever wondered why you have to change your air filter regularly? Here are a few reasons why changing your air filter at least every 90 days is so important.

Changing your air filter is a home maintenance task that is often overlooked because

  1. It’s hidden, it’s not something we see every day
  2. The effects of not changing your filter are not obvious

You might be thinking: what’s the big deal?  Do I REALLY need to change them that frequently?  Here’s what happens when you do not change your air filter regularly.

System Inefficiency & Failure:

When your air filter is dirty and clogged with debris, air cannot flow through properly.  This is the #1 reason for system inefficiency and failure. The added strain on the fan motor can cause it to overheat and eventually fail to operate. In the meantime, stressing the system forces more energy consumption leading to higher electricity costs and utility bills.

Poor Air Quality:

Today’s air filters are specially designed to remove many harmful contaminants from indoor air.  Dirty air filters decrease contaminate catching efficiency of the filter media. Depending on the MERV rating you choose, contaminants that are removed include:

  • Lint and Dust
  • Pollen
  • Pet Dander
  • Mold
  • Dust Mites
  • Auto Emissions
  • Smoke
  • Bacteria

Dirty House:

Dirt, dust, and debris from dirty air filters cause heating and air conditioning system and air ducts to become dirty faster.  This dirt and dust, in turn, will be re-circulated into your home out of the ventilation systems causing a much dustier living space.

Bad for the Environment:

Dirty air filters increase your carbon footprint because they force the system to work harder using more energy.

As you can see there are legitimate reasons why it is necessary to replace your furnace and air filters on a regular basis.  Improving indoor air quality by removing harmful contaminants, keeping your house clean longer, saving money on high utility bills and decreasing your carbon footprint are all good reasons to make sure you replace your filters.  Most require either monthly changes or every 3 months.  This will depend on the type of filter you use.
