How Often To Change Your Furnace Filter

A furnace filter is a crucial component of your home's heating and cooling system. It is responsible for capturing dust, dirt, pet hair, and other particles that would otherwise circulate in your home's air. Regularly changing your furnace filter ensures that your HVAC system runs efficiently and effectively, and helps maintain good indoor air quality. So, when should you change your furnace filter?

Key Factors

Most experts recommend changing your furnace filter every 1-3 months, depending on several factors. The first factor to consider is the type of filter you have. Different filters have different lifespans, and some need to be changed more frequently than others. For example, disposable fiberglass filters typically need to be changed every month, while higher-end pleated filters can last up to three months or longer.
The second factor to consider is the level of usage your HVAC system gets. If you live in a large household or have pets, you may need to change your filter more frequently, as more contaminants will be present in the air. Similarly, if you live in an area with high levels of pollution or construction work nearby, you may need to change your filter more often.
The third factor to consider is the time of year. In the winter, when your furnace is working hard to keep your home warm, you may need to change your filter more frequently. This is because your furnace is circulating more air, and more contaminants are present in the air during the colder months.

Signs Your Filter Needs Changing

So, how can you tell if your furnace filter needs changing? There are several signs to look out for. The first is reduced airflow. If you notice that your home's heating or cooling system is not working as efficiently as it used to, it may be because your filter is clogged with dirt and debris. A clogged filter restricts the airflow, making it harder for your HVAC system to circulate air throughout your home.

Another sign that your filter needs changing is increased dust in your home. If you notice that there is more dust settling on your furniture, floors, and other surfaces, it may be because your filter is no longer capturing the particles in the air.

Lastly, if you notice that your allergies are worsening, it may be because your filter is not doing its job properly. A clogged or dirty filter allows allergens to circulate in your home's air, exacerbating allergy symptoms.

In summary, changing your furnace filter is an important part of maintaining good indoor air quality and ensuring that your heating and cooling system runs efficiently. Most experts recommend changing your filter every 1-3 months, depending on factors such as the type of filter you have, the level of usage your HVAC system gets, and the time of year. If you notice reduced airflow, increased dust, or worsening allergies, it may be time to change your filter. By keeping on top of your filter changes, you can enjoy a healthier and more comfortable home environment.
