Air filters are an important component of an HVAC system, and knowing how to maintain them properly is essential for keeping the air in your home clean and healthy. In this article, you’ll find out everything you need to know about HVAC air filters. Keep reading to learn more.
What do HVAC air filters do?
Air filters for heat pumps and other systems are an essential component of any HVAC system. They are designed to filter out pollutants, dust, and other airborne particles from the air that is circulated throughout the home or office. The filter traps these particles and prevents them from being circulated in order to provide quality indoor air. In addition to improving indoor air quality, air filters can also help the HVAC system run more efficiently, reducing energy costs. HVAC air filters come in a variety of shapes and sizes and are made of different materials, depending on the type of air filter needed.
What are the different types of air filters?
HVAC air filters play an important role in improving the air quality of a home or office. They help to remove allergens, dust, and other particles from the air, protecting people from breathing in potentially harmful pollutants. There are three main types of HVAC air filters: fiberglass, pleated media, and HEPA filters.
Fiberglass HVAC filters are made of an inexpensive material that is designed to trap large particles like dust and pet dander. These filters typically come in disposable, washable, and electrostatic models and are the most cost-effective option for basic air filtration. They typically have a MERV rating of 1 to 4, meaning they are designed to remove larger particles from the air, such as pollen and lint, but do not remove smaller particles, such as dust and smoke. They are not as effective as other types of filters but provide standard filtration.
Pleated media filters are made of a dense material that traps smaller particles than fiberglass filters. The pleats give the filter more surface area, making it more effective at trapping tiny particles like smoke and bacteria. Pleated media filters typically have a MERV rating of 5 to 13, meaning they are more effective at removing smaller particles from the air. These filters are more expensive but can last longer before needing to be replaced.
High efficiency particulate air filters (HEPA filters) are the most effective type of HVAC air filter. HEPA filters are made from a combination of fibers, adhesives, and a frame. They are designed to capture 99.97 percent of particles that are 0.3 microns or larger, making them effective at removing a wide range of particles from the air, including larger particles such as pollen and lint, as well as smaller particles such as dust and smoke. HEPA filters typically have a MERV rating of 17 to 20, meaning they are the most effective at removing particles from the air.
How do you install an air filter?
Installing your air filter correctly is essential for the optimal performance and efficiency of your HVAC system. The first step in installing an HVAC air filter is to measure the size of the filter you will need. The size of the filter should match the size of the filter slot in your unit. If you have an older unit, you may need to measure the size of the filter slot and purchase a new filter that will fit. Most air filters are installed with arrows pointing toward the unit. This will ensure that the air flows through the filter in the right direction. Make sure that the filter is secure and that there are no gaps in the filter that can block airflow. If you need help installing an air filter, you can refer to the manufacturer’s instructions or contact an HVAC technician.
How often do you need to change HVAC air filters?
While HVAC air filters are designed to last for several months, it is important to know when and how often to change them in order to keep your HVAC system functioning properly and efficiently. The frequency at which you need to change your HVAC air filters depends on a few factors, such as the size of the filter, the type of filter, and how often the system is used. Generally speaking, disposable filters should be changed every 30 to 90 days. It is important to note that you may need to change your filter more often if you have pets, smoke, or have a large family.
No matter if you have a heat pump or other type of equipment, air filters are an important part of any home’s HVAC system. They are necessary to preserve indoor air quality and to ensure that the system runs as efficiently as possible.
