Different types of HVAC filters!

     Heating, ventilation, and air conditioning (HVAC) systems are essential for maintaining the indoor air quality of commercial and residential buildings. One critical component of these systems is the air filter, which removes airborne contaminants such as dust, pollen, and other particulate matter from the air. There are several types of HVAC air filters available, each with unique characteristics and filtration capabilities. In this blog post, we will explore the different types of HVAC air filters available in the market and their applications.


     Fiberglass filters are the most commonly used HVAC air filters. These filters are made from spun fiberglass material and are relatively inexpensive. They are designed to capture large particles such as dust and debris, but they are not very effective at removing smaller particles such as allergens and bacteria. Fiberglass filters have a MERV rating between 1-4, indicating their ability to capture large particles.


     Pleated filters are made from polyester or cotton material and are designed to capture smaller particles than fiberglass filters. They have a MERV rating between 5-13, indicating their ability to capture small to large particles. Pleated filters have a larger surface area than fiberglass filters, which allows them to capture more particles. They are more expensive than fiberglass filters, but they provide better filtration.


     Electrostatic filters use a static charge to attract and capture particles in the air. These filters are available in two types: washable and disposable. Washable electrostatic filters are designed to be cleaned and reused, while disposable electrostatic filters are discarded after use. Electrostatic filters have a MERV rating between 8-12, indicating their ability to capture small to large particles. They are more expensive than fiberglass and pleated filters, but they provide superior filtration.


     High-efficiency particulate air (HEPA) filters are the most effective type of HVAC air filter available. These filters are made from a dense, tightly packed mesh of fibers that capture even the smallest particles, including allergens, bacteria, and viruses. HEPA filters have a MERV rating of 17-20, indicating their ability to capture the smallest particles. They are commonly used in hospitals, laboratories, and other environments that require high levels of air filtration.


     Filters require regular maintenance and change outs. Other-wise issues arise from blocked airflow including frozen coils and burned-out fan motors.


     In conclusion, there are several types of HVAC air filters available in the market, each with unique characteristics and filtration capabilities. Fiberglass filters are the most commonly used filters, while pleated filters are more effective at capturing smaller particles. Electrostatic filters provide superior filtration but are more expensive than other filters. HEPA filters are the most effective type of filter available but are also the most expensive.
