When it comes to keeping your HVAC system running smoothly, there are a few components that need regular maintenance. One of those is the air filter. It traps debris and dust to keep your indoor air clean, and it needs to be changed on a regular basis to ensure optimal performance. But what exactly do you need to replace? There are a few common filters that all HVAC systems use, but they all serve the same purpose of cleaning the air before it reaches the rest of the house. Here’s a breakdown of some of the most common HVAC filter parts:

What is an HVAC filter?

An HVAC filter is a mesh or pad that sits in front of the blower in your HVAC system. It’s designed to trap dust and debris in the air so that it doesn’t reach the rest of your home. Different types of filters are used for heating and cooling, depending on your climate and the type of system in your home. There are three main types of HVAC filters: air, water, and oil. The air filter is the most common type of filter, and it traps airborne dust, pollen, and other contaminants that can pollute your indoor air. There are two main types of air filters: disposable and reusable. Disposable filters are usually made from paper or polyester fibers, and they’re designed to trap larger dust and debris. Reusable filters are usually made from polyester or fiberglass mesh, and they’re designed to trap smaller dust and debris.

Carbon filter

A carbon filter is a type of air filter that’s used to remove odors and harmful gases from the air. It’s often used in large commercial HVAC systems, but it’s also commonly found in smaller systems in homes. A carbon filter is made from activated carbon, which is a type of charcoal that’s used to trap harmful gases such as formaldehyde and mercaptan. Activated carbon is also used in water filters and is a very effective way to remove contaminants from water. Carbon filters are usually installed in the outdoor section of a HVAC system, and they’re used to filter the air that’s pumped into the home. They’re especially important in areas with high levels of pollution, such as cities with lots of industrialization.

HEPA filter

A HEPA filter is a very high quality filter that’s used to trap very small particles in the air. They’re often used in areas with high levels of pollution, such as hospitals. A HEPA filter is very effective at removing dust, pollen, mold spores, smoke, and pet dander from the air. They’re commonly used in heating and cooling systems to filter the air that’s pumped into the home. HEPA filters are usually installed in the outdoor section of a HVAC system, and they’re used to filter the air that’s pumped into the home. They’re especially important in areas with high levels of pollution, such as cities with lots of industrialization.

Activated alumina filter

An activated alumina filter is a type of air filter that’s used to clean the air in a home that’s been treated with ozone. They’re commonly used in hospitals, and they’re also used in HVAC systems to filter indoor air. An activated alumina filter is made from alumina, which is a naturally occurring compound that’s combined with an activating agent to create an activated alumina filter. Activated alumina filters are very effective at removing gases, chemicals, and viruses from the air. They’re commonly used in hospitals and HVAC systems to filter indoor air. They’re especially important in areas with high levels of pollution, such as cities with lots of industrialization.

Conclusion

An HVAC filter is an important part of any HVAC system. It traps dust and debris in the air before it reaches the rest of your home, which is why it’s so important to change it regularly. There are different types of filters, including carbon filters, HEPA filters, and activated alumina filters, each with different uses. It’s important to change your HVAC filter on a regular basis to ensure that your system is running efficiently and effectively.

Frequently Asked Question

You should change your air filters every 90 days. However, if you have allergies, you better change them after 45 days. It also depends on the MERV rating of the filters you are using. On average, it is highly recommended to change your air filters every 90 days. 
Yes, it does. There are many types of air filters and their performance is based on their material and most of the time their MERV rating. Choosing the best one will make a huge impact on how long your HVAC system will last.
HVAC air filters have different variations depending on their quality and sizes. Most HVAC manufacturers would recommend buying a new air filter that is compatible with HVAC. These air filters have a Minimum Efficiency Reporting Value or MERV which will tell you their overall performance in filtering contaminants in the air.
Most likely it will not filter the air properly. Dust will accumulate on your filter thus affecting some parts of your Air Conditioning unit. Aside from not being able to work properly in filtering the air, it will damage the system of your AC, because the airflow is affected.
