Air filters come in a variety of shapes, sizes, and types. The five most common air filters are pleated filtration, panel or flat-media filters, HEPA or high-efficiency particulate air filters, activated carbon filters, and ultraviolet germicidal irradiation (UVGI) systems. Each type of filter has its unique benefits and drawbacks. Which one is right for you depends on your specific needs. Keep reading to learn more about the different types of air filters and how they can help improve your indoor air quality.
5 Different Types of Air Filters
Air filters are essential components of the HVAC system in our homes. They help to purify the air, removing dust, pollen, and other harmful particles. Several types of air filters are available, each with unique features and benefits. Here are five of the most common types of air filters you can choose from:
Pre-Filters
Pre-filters are an important part of any air filtration system. They help to remove large particles such as dust, hair, fur, and pollen before they enter the system, which keeps the primary filters clean and extends their life. Because these large particles can cause system blockages and decrease air quality, pre-filters are critical for ensuring your home or workplace is always properly filtered. Pre-filters work by trapping solid particles on the filter's surface through a process known as mechanical filtration. This way, unwanted contaminants that cause poor air quality never enter your living or working space. Investing in regular pre-filter replacements can save you from costly repairs.
Hepa Filters
HEPA filters are a special type of air filter that can trap particles as small as 0.3 microns, such as dust, pollen, and pet dander. Installing a HEPA filter in your home can drastically reduce airborne allergens and other small particles, relieving those with allergies or asthma. Compared to other air filters, HEPA filters are known to be more effective at trapping airborne particles, so if you're looking for the best possible way to rid your indoor space of pollutants, investing in a HEPA filter is a wise choice.
Activated Carbon Filters
Activated carbon filters are an effective way to remove odor and chemical contaminants from the air. These filters contain carbon treated with oxygen, creating tiny pores and channels designed to capture particles. Air passes through these channels and is filtered from pollutants, unpleasant smells, and other harmful chemicals. Activated carbon filters are highly effective and affordable compared to some of the different types of air filters on the market. Furthermore, they need minimal maintenance since they don't require frequent changing. For any home looking for a powerful and cost-efficient way to clean indoor air, activated carbon filters are a great option.
Ultraviolet Germicidal Irradiation (UVGI) Filters
Ultraviolet germicidal irradiation (UVGI) filters can provide a powerful layer of defense against bacteria and viruses in the air. UVGI technology is used to destroy airborne microorganisms without using hazardous chemicals. It makes it safer to use around people and animals than other air filters. In addition, UVGI filters are more environmentally friendly as they do not require ongoing replacement or disposal of chemicals or particulate matter. UVGI filters also eliminate harmful odors, providing additional protection and comfort in any indoor environment.
Electrostatic Precipitation (ESP) Filters
Electrostatic precipitation (ESP) filters are efficient and effective air filters that capture charged particles in an electrical field. It is made possible by the polarized media, which distributes electrical charge onto the filter, and aluminum separators that help create a strong electric field. ESP filters reduce dust and other airborne particles, including allergens, using electrical and mechanical forces. Furthermore, they can be used with multiple stages to separate different-sized particles further; this helps them deliver a very high filtration efficiency for all indoor air quality applications. With their capacity for fine particulate matter, ESP Filters are the ideal choice for anyone looking for an extremely reliable and consistent air filter system.
Conclusion
Air filters are an important part of any HVAC system, and there are various air filters to choose from, depending on your needs. Pre-filters remove large particles from the air before it enters the system, while HEPA filters trap small particles like dust, pollen, and pet dander. Activated carbon filters absorb odors and chemicals from the air, UVGI filters kill bacteria and viruses, and ESP filters capture charged particles in an electrical field.
