How Often Should I Change My Air Filter?

HVAC, Indoor Air Quality

When it comes to replacing your HVAC system’s air filter, whether it be an AC or furnace, there is no absolute rule or answer to this question – however, it is vital to keep your air filter fresh to maintain optimal indoor air quality. Several factors should be taken into consideration when determining whether to replace air filters, for example, how dirty is the filter? If it’s dirty, it’s time to replace it. Having said that, however, it’s best to avoid allowing the filter to become completely dirty or clogged because your HVAC system needs a clean air filter to breathe, essentially to deliver its full potential throughout your residence. To help you determine when it’s time to replace your air filter, we at Lebanon Heating & Cooling present the following factors for consideration.

Do You Suffer From Allergies?

If you or anyone else in your home suffers from allergies, you might want to replace your air filter more frequently. Why should you replace it frequently? Because doing so will help remove indoor air pollution such as allergens. Replacing your air filter frequently allows you to breathe better cleaner air. When an air filter is dirty, it is not able to trap these airborne particles or allergens thus making allergy symptoms worse.

What Type of Filter Do You Have?

Air filters come in a variety of shapes and sizes. From the type of material they are made with to how thick they are to their form – there are a variety of different types of air filters. When considering what type of air filter to get, it’s important to keep in mind that buying a cheaper air filter can actually cost you more money in the long run. An inexpensive or cheap air filter will need to be replaced more often than one of better quality. If you are able to, we encourage you to spend a little more on a higher quality air filter because you won’t have to replace as often and it will improve your indoor air quality, catching airborne particles and pollutants.

Are There Pets in the Home?

Our furry little companions are like members of our family. However, they often shed like crazy. When a home has furry critters, pets, living within, your home’s air filter will need to be changed more frequently. Dog and cat fur, in addition to dander, spread throughout your home ‒ and a lot of it ends up in your air filter. As such, it’s important to understand that depending on which season it is, you will probably need to replace your air filter more frequently. Also, keep in mind that our beloved animals usually shed the most when the weather is warmer.

Replacing an air filter is a crucial component affecting the quality of air in a home. Not only can it make you and your family breathe better, but it can also help save you some money. Dirty filters restrict the airflow causing the HVAC system to work harder, which may decrease the lifespan of your system.
