Maintaining healthy indoor air quality (IAQ) at home has become a top priority for virtually everyone in recent years. Largely due to increasing amounts of time spent at home, more people have become aware of the direct correlation between indoor air quality and one’s overall well-being. In parallel, more office workers have experienced Sick Building Syndrome, which has further increased awareness around the importance of home wellness, especially among hybrid workers.

The Environmental Protection Agency (EPA) has reported that indoor pollution levels can be up to five times higher than those found outside, which can lead to various health problems, including allergies and asthma.

When aiming to improve your home’s air quality it’s imperative to maintain your HVAC system proactively. HVAC systems help regulate the temperature and humidity levels inside your home while also filtering out dust, allergens, and other pollutants from the air. However, they can only function optimally when their air ducts and filters receive regular maintenance. In this article we take a closer look at the role of HVAC filters in air duct maintenance and why it’s important to keep them clean and replace them periodically.

What are HVAC Filters and What Do They Filter Out?

HVAC filters are essential components of your heating, ventilation, and air conditioning (HVAC) system. Their primary function is to filter out dust, pollen, pet dander, and other airborne particles that can compromise indoor air quality and negatively impact your health. Filters come in different types and sizes and feature materials, such as pleated paper, fiberglass, and polyester.

Why Do You Need to Change Your HVAC Filters Periodically?

As HVAC filters trap airborne particles, they become clogged with dirt and debris. When too much accumulates, it reduces the efficiency of your HVAC system, making it work harder than necessary to regulate the indoor temperature and humidity levels of your home. Clogged HVAC filters will then lead to higher energy bills and unnecessary wear and tear on your HVAC system. For optimal performance, change your filters periodically.

How Often Should You Change Your HVAC Filters?

The frequency of HVAC filter changes depends on factors like the type of filter, the size of your home, amount of usage, and the number of pets you have. Generally, changing your filters every one to three months is ideal, but some high-efficiency filters can last up to six months. If you notice visible dust buildup on your filters or experience reduced airflow, that’s a good indication that it’s time to change your filters.

How Can You Maintain Clean Air Ducts?

In addition to changing your filters regularly, there are other common HVAC ductwork problems to avoid. One of the most important things you can do is vacuum and dust your home regularly to minimize the airborne particles entering your HVAC system. You can also seal any leaks or cracks in your air ducts to prevent dust and other pollutants from entering your air ducts.
