How Often Should You Change Furnace Air Filters?

The air inside your home has a major influence on the quality of life of you and your loved ones. Therefore, maintaining your Furnace Air Filters is an important chore. It is even more critical for those who suffer from allergies or respiratory problems.

Here is a detailed guideline to Furnace Air Filter in Ottawa and how often should you change it.

What is the Use of a Furnace Air Filter?

Your furnace air filter traps airborne pollutants and cleans your air. While it does that, it is not a filter's only job. 

A furnace air filter's primary goal is to catch airborne pollutants, not to improve air quality. Since the filter removes pollutants, it also acts as an advantage for the air quality.

How often should You Change Furnace Air Filters?

The frequency of changing furnace air filters varies from home to home. The regularity of changing depends on the type of furnace air filter that you have installed. As a result, changing the filters could be once a month to once a year. 

Just as there are various filter types, similarly, there is a broad range of how to replace filters. Nevertheless, replacing furnace filters isn't a guessing game.

You can take help from the product information of the furnace air filter. This manual will have all the information you wish to require.

Here's a quick guideline to give you a head start:

Thicker filters have more media to trap pollutants. Therefore, a 5-inch filter has to be changed less frequently than a 1-inch filter. 

Filter efficiency also has an effect which is measured in MERV (Minimum Efficiency Reporting Value).

In general, this is how frequently you should change furnace air filters:

1 to 2 inches filters should be replaced every 1 to 3 months.

3 to 4 inches filters should be replaced every 6 to 9 months.

5 to 6 inches filters should be replaced every 9 to 12 months.

Never Forget to Change Your Furnace Air Filters!

We all know by now that changing the furnace air filter is good for your HVAC system and your health. 

But like out of sight is out of mind. Your HVAC has similarly hidden away. However, this is an important chore that must be prioritised. 

It's smart to check your filter once a month to see how it's doing, as your system may need early furnace filter replacement. 

In addition, there are few tips to help you remember:

1 - Mark monthly filter checks on your calendar.

2 - You can even schedule reminders on your smartphone.

3 - Checking and changing furnace filters can be done with other important monthly tasks. For example, you can check the filter status when paying your monthly electricity bill. 

To sum it up

Taking care of your Furnace Air Filters has a major influence on your home's comfort and indoor air quality. They also add up to your HVAC system's performance, energy efficiency, and lifespan.
