Everything to Know About HVAC Filters
One of the vital parts of an HVAC system is filters.
Regardless of the model, size, power, and age, every HVAC system requires regular maintenance and care. By ensuring their HVAC system is in excellent condition, homeowners reduce the risk of sudden malfunctions, maintain good air quality, and extend the system’s lifespan. One of the vital parts of an HVAC system is filters. Here, homeowners can learn what HVAC filters are, their function, and when to replace them.
What are HVAC filters?
HVAC filters are an essential component of every HVAC system. They collect impurities such as bacteria, pet dander, and dust, removing them from the air flowing through the system. Besides improving the air quality, HVAC filters ensure the system operates smoothly. In addition, the filters “protect” the other components from damage by collecting the impurities.
Different types of HVAC filters
Various HVAC filters differ in shape, materials, capabilities, and prices.
Flat-panel filters
Flat-panel filters are the most traditional and affordable type of filter. They typically feature fibers stretched over a framework to collect impurities.
These filters are easy to install and replace. However, they have a significant drawback compared to other types of filters: lack of efficiency. Flat-panel filters aren’t of the highest quality and often allow larger particles to get through, thus compromising the air quality and damaging the system components.
Pleated filters
Pleated filters feature cotton or plastic fiber screens that collect particles from the air. These filters have pleats that catch more debris thanks to their large surface but are more expensive than flat-panel filters.
Electrostatic filters
Electrostatic filters are electrically charged and highly efficient. Such filters can collect particles like pollen, bacteria, or smoke. Both flat-panel and pleated filters can be electrostatic.
High-efficiency particulate air (HEPA) filters
HEPA filters remove at least 99.97% of particles, 0.3 microns or larger. These filters are usually used in laboratories and hospitals, but many households use them nowadays. In addition, people with allergies or a compromised immune system find them valuable.
HVAC filter rating
All air filters are rated based on their ability to remove impurities from the air. The standard scale for measuring air filter efficiency is Minimum Efficiency Reporting Value (MERV). The scale ranges from 1 to 16, and it was developed by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers. Number one marks filters with the lowest efficiency, while 16 marks the ones with the highest.
Numerous brands have designed their scales for rating HVAC filters. For example, Home Depot uses Filter Performance Rating, and 3M uses Microparticle Performance Rating.
Take care of the HVAC filters
The efficiency of HVAC filters decreases over time, and they will require a replacement at some point. Homeowners should reach out to professionals if unsure when and how to replace HVAC filters. These professionals will examine the HVAC system and recommend the ideal solution. They can also suggest the filters that offer the best value for money.
