A filter is an essential component of any HVAC system. It traps debris and other contaminants in the air before they reach the other parts of the system, keeping them from damaging the motor or other components. It’s also important to understand that a filter doesn’t just trap dirt and dust — it can also trap bacteria, viruses, pollen, and other harmful contaminants that could otherwise cause serious health issues. Depending on the type of filter you use, it can trap anywhere from 80% to 99% of harmful contaminants in the air. Furnace filters are typically made of polyester or fiberglass, and are designed to trap large particles, like sand and dust. They are also sometimes referred to as air-conditioning filters or HVAC filters. While they might not be the first thing you think of when it comes to HVAC maintenance, they are an essential part of your system that needs to be kept clean and in good working order at all times. There are different types of filters for heating and cooling systems, and they all have different functions depending on the type of system they are installed in. Here’s what you need to know about them:

What are the different types of HVAC filters?

There are two main types of HVAC filters: A mechanical filter and an electrostatic filter.A mechanical filter is the most common type of filter used in HVAC systems. It’s usually made of polyester or fiberglass and can trap 80% to 95% of airborne contaminants. This type of filter is usually placed inside the air ducts and is responsible for cleaning the air before it reaches your living space.An electrostatic filter, on the other hand, is used to trap 99% of airborne contaminants in HVAC systems. It’s designed to trap even smaller particles than a mechanical filter.These two types of filters don’t necessarily compete with each other; instead, they work in tandem to clean the air of harmful contaminants. You can even use both types of filters at the same time to clean the air even more efficiently.

How do HVAC filters work?

When you first turn on your HVAC system, it draws in air from the outside and pushes it through the filter. As the air travels through the filter, the dirt and other contaminants are trapped by the filter mesh. Once the air exits the filter, it’s clean and ready to be pumped into your home. Depending on the type of filter you have and how dirty it is, you might need to change it once or even twice a year. The longer you wait to change your filter, the more dirt and dust will be trapped inside the filter. This could lead to decreased airflow and reduced efficiency, which means more money spent on HVAC services.If your HVAC filter is dirty, the air that comes out of your system will be dirty too. This means that you and your family will be breathing dirty air, which is not only unappealing but could also be harmful to your health. Not only will this result in a lower quality of life, but it could also lead to more costly HVAC services in the long run.

How much do you need to change your HVAC filter?

The frequency you need to change your HVAC filter depends on several factors, including the type of air filter you use, the size of your home, and the amount of dust and dirt in your environment.The general rule is to change your HVAC filter once a month, or once every two months if you live in a particularly dusty environment. But if you’re particularly sensitive to dust, you might want to change it more frequently.The type of filter you use also affects how often you need to change it. If you have a mechanical filter, you should change it once a month. If you have an electrostatic filter, you’ll need to change it once a week.

Benefits of keeping your HVAC filters clean

Regularly cleaning your HVAC filters is an important part of maintaining your system. Not only does it help clean the air of harmful contaminants, but it also prevents bacteria and mold from growing inside your system and potentially causing serious health issues.It’s also important to note that regularly cleaning your HVAC filters can help you save money on your utility bills. This is because dirty filters can reduce the amount of air that can be pumped through your system, which means you’ll have to run your HVAC system more frequently to maintain a comfortable room temperature.This can lead to higher energy bills, which is why it’s important to clean your HVAC filters regularly to avoid paying more for your energy services.

Frequently Asked Question

The furnace filter needs to be replaced depending on your location. For colder zones, you might want to change it every 30 – 60 days because furnaces usually go on for many months and do not take a break. For warmer areas, you may only replace it twice during the winter or after 90 days. It also varies on the thickness of the furnace filters. The thinner your filter, the more frequent you get to replace it.
If you fail to change your furnace filter, this might affect the performance of your furnace. It will pressure your equipment to work harder because of a decrease in airflow. Worse, it might damage your equipment forcing you to have it repaired or replaced. The furnace will overheat once you turn it on without a new air filter.
Technically without a furnace filter, your furnace will still operate. However, you will risk your family’s health and your equipment’s performance as well. Furnace filters make sure that contaminants, dust, and microbes do not get inside your house so you will not breathe dirty air.
A dirty furnace filter looks darker than the first time you bought it. The air also smells funny. You get lower airflow and your equipment works hard causing your electric bills to soar. Soon you will get sick, and develop headaches and allergies.
The fibers can’t do their job when it is placed backward. The furnace will work harder to keep up with its desired output. This will increase your energy cost and damage your equipment. Smaller particles will accumulate causing build-up.
