How Often Do You REALLY Need to Change Your HVAC Filter?

Have you been putting off changing your HVAC air filter? The temptation can be to procrastinate just a little while longer, but a dirty air filter is actually harmful to both your home and your health. Let’s take a closer look.

What is the Lifespan of an Air Filter?

The lifespan of an air filter varies based on brand, size, and workload. Generally, there will be a recommended time of use on the front of the filter’s package, which you should write down. However, if you have pets, children, or tend to overwork your system, it might not hurt to change your furnace filter more often than the package suggests.

If you still aren’t sure, a good rule of thumb for the average home is to change 2″ filters every three months, 4″ filters every six months and 5″ filters every year. This will prevent pollutants from entering your ductwork and lowering your home’s indoor air quality.

Signs Your Furnace Filter Needs to Be Changed

1. You can see dirt on the filter.

It stands to reason that if your filter is visibly dirty, it needs to be changed! Even if you don’t notice poor air quality in your home, you should check your air filter regularly to ensure no dirt is building up. If it is, change it before it begins negatively affecting your home.

2. Your home is dusty.

A filter’s purpose is to prevent unwanted dust, dirt, particles, and pollutants from cycling through the air in your house. If your home is dirtier or dustier than usual, it could be that your air filter isn’t doing its job because it needs to be changed.

3. You are experiencing allergy problems.

One of the side effects of poor indoor air quality is difficulty breathing. You might think you’re suffering an allergic reaction to the pollutants outside, but if your air filter is dirty, it might be the inside pollutants causing you discomfort.

4. You notice strange odors.

Burning smells coming from your HVAC unit typically point to a dirty furnace filter. Don’t ignore the warnings of your nose. Investigate!

Other Things that Affect Your HVAC System

• Animals
  As already mentioned, if you have pets, your HVAC system will likely need to be inspected more regularly.

• Smoking homes
  Cigarette smoke can significantly lower indoor air quality and cause many health issues, as well as problems with your HVAC system.

• Dust
  You want to keep too much dust from settling into your ductwork, so do your best to keep the rest of your house clean and dusted.
