Do You Need to Change Your Air Filters?

Are you wondering if it's time to replace the air filters in your HVAC system? It's an important question, as replacing them too often can be a waste of money, while not replacing them often enough can lead to reduced air quality and even damage to the HVAC system. Let's take a look at why air filters need to be replaced and how often they should be changed.

Why Do Air Filters Require Replacing?

Air filters become clogged with dirt, dust, and other airborne particles over time. This buildup will reduce the efficiency of the filter, making it less effective at trapping pollutants. It can also cause your HVAC system to work harder than necessary, leading to increased energy costs.

How Often Should You Replace Your Air Filter?

The frequency with which you should replace your air filter depends on several factors such as the type of filter being used, the level of air pollution in your area, and how often you use your HVAC system. Generally speaking, most air filters should be replaced every three months or so.

Factors That Affect How Often To Replace Air Filters

In addition to these factors, there are several other things that may affect how often you need to change your air filter. These include:

• Type of Filter: Different types of filters have different lifespans - for example, disposable fiberglass filters typically need replacing more frequently than pleated ones.
• Level of Air Pollution: The higher the level of pollution in your area is likely to mean that you'll need to change more regularly.
• HVAC System Usage: If you use your HVAC system frequently then this could mean that you'll need to change more regularly than someone who doesn't use it as much.
• Pets: If there are pets in your home then they may shed fur and dander which can quickly clog up an air filter - meaning that it needs changing more frequently.
