Furnace Filters

A furnace filter is placed in the air intake of the HVAC system so that any airborne pollutants can be caught before it enters the HVAC system and is circulated into your home. It captures the dirt, dust, and any other allergens that would potentially circulate around your home, ensuring that the air you breathe is clean and fresh. Furnace filters come in three distinct types and vary in their effectiveness.

HVAC Systems

The HVAC system, which stands for heating, ventilation, and air conditioning, is what is responsible for keeping the temperature in your home at a comfortable level. The system is composed of various components working together such as the furnace, the blower, and the ductwork, which can transport the air all throughout the home. Each component works together to create the perfect environment for your home.

Airflow & Clean Air

Regularly changing your furnace filers is important because it ensures that the air is properly circulated throughout the home. When the furnace filter is dirty, the air it is trying to move has to work harder to get past the filter, causing it to become restricted. This restriction of airflow can slow down the operation of the HVAC system, reducing the overall efficiency of your system.

How Often Should I Change My Furnace Filter?

It is recommended that the furnace filter should be changed every month. This ensures that your filter does not become clogged with dirt, dust, and allergens and is able to continue to provide you with clean and fresh air. If you live in certain climates that are more susceptible to accumulating dust and dirt, then it is suggested to change your furnace filter every two to three months.

What Type of Filter Should I Use in My Furnace?

When it comes to the type of furnace filter you should use, there are three main types to choose from. The first is a disposable filter, the second is a washable filter, and the third is an electronic filter. The type of filter you use depends on your preference, budget, and needs.

Disposable Filters – These are the most common type of filter and are the most cost-effective. They are effective at catching common pollutants such as dust and pollen, but they do need to be replaced often.

Washable Filters – These are more expensive than the disposable ones, but they do not need to be replaced as often. The downside is that they need to be cleaned regularly in order to be effective.

Electronic Filters – These are the most expensive type of filter and are effective at catching finer particles such as pet dander, bacteria, and smoke. They need to be replaced approximately every two years.

What Benefits Do I Receive by Regularly Changing My Furnace Filter?

By regularly changing your furnace filter, you are ensuring that your HVAC system is working as efficiently as possible. A clogged up filter causes the air to be restricted, which can reduce your HVAC systems efficiency. By keeping your system working at its optimum level, you can reduce your energy bills, as the system is not having to work harder to move the air. In addition, you will be ensuring that the air you breathe in your home is clean and free from pollutants.

What Happens if I Don’t Change My Furnace Filter Regularly?

If you don’t regularly change your furnace filter, then it can put a lot of strain on your HVAC system. This can lead to an increase in your energy bills as the system has to work harder to circulate air through the filter. Additionally, this can also lead to a reduction in the air quality of your home as all the pollutants won’t be filtered out.


It is essential for anyone with an HVAC system to regularly change their furnace filter. It is essential for keeping your system running at its optimal level, reducing your energy bills, and ensuring the air quality in your home is kept clean. There are different types of filters to choose from depending on your needs and budget, but changing the filter a few times a year will keep your system running efficiently and your air clean.
