There are several types of air filters, including panel filters, minimum efficiency rating value filters, extended surface filters, rigid box filters, rigid cell or cartridge filters, high-efficiency particulate air (HEPA) filters, reusable or washable filters, fiberglass filters, pleated filters, pocket filters, bag filters, metal V-form filters, and HEPA filters. These filters offer different levels of filtration for various particles in the air.
Some filters can be cleaned, while others are disposable. It is important to choose the right type of air filter for your HVAC system to maintain clean and healthy indoor air quality.
Types Of Air Filters
Types of Air Filters:
- Panel Filter: Panel filters are the most common type of air filters used in HVAC systems. They consist of a fibrous filter media enclosed in a cardboard or metal frame. Panel filters are effective at capturing dust, pollen, and other larger particles.
- Extended Surface Filter: Extended surface filters, also known as pleated filters, have a larger surface area that allows for greater dust-holding capacity. They are often made of polyester or fiberglass material and can capture smaller particles.
- Rigid Box Filters: Rigid box filters are designed for high-velocity airflow applications. They have a rigid frame and a filter media made of synthetic fibers or activated carbon. These filters are commonly used in commercial buildings.
- Rigid Cell or Cartridge Filters: Rigid cell or cartridge filters are designed for industrial applications and can handle high airflows and heavy dust loads. They have a pleated filter media and a rigid frame made of metal or plastic.
- HEPA Filters: HEPA filters are the most efficient air filters available. They can capture 99.97% of particles as small as 0.3 microns. HEPA filters are commonly used in cleanrooms, hospitals, and other environments that require extremely high air quality.
Different Types Of Hvac Filters
Reusable or washable filters are a popular choice for many homeowners. These filters can be cleaned and reused multiple times, making them a more eco-friendly option. They are typically made of a durable material that can withstand regular cleaning without losing their effectiveness.
Fiberglass filters are the most common type of air filter found in residential HVAC systems. They are made of fine fiberglass strands densely woven together, which helps to capture larger particles like dust and dirt.
Pleated filters have a larger surface area than flat fiberglass filters, allowing them to capture more particles. They are constructed with pleats that create more space for air to flow through, increasing their efficiency.
Bag filters are designed for commercial HVAC systems and can filter out a wide range of particles, including pollen, dust, and bacteria. They consist of a bag-shaped filter media that offers a high level of filtration.
Metal V-form filters are commonly used in industrial settings where there is a high concentration of airborne contaminants. They are made of metal sheets arranged in a V-shape, which increases their surface area and allows for efficient particle capture.
Choosing The Right Filter
When selecting the right air filter, consider various types such as Panel, Rigid Box, and HEPA Filters. Each type offers specific benefits for air quality improvement and system efficiency, catering to different HVAC needs. Choose wisely for optimal performance and indoor air freshness.
| Benefits of Pleated Air Filters | ✓ Trap more dust and allergens |
| Advantages of Pocket Filters | ✓ High dust holding capacity ✓ Suitable for high-velocity air systems |

Air Filter Material
There are various types of air filters available, each with different filtering materials. The Aerostar MERV Pleated Air, Trion Air Bear Filter, and Frost King Window Air Conditioner are some examples of air filters with different filter materials. It’s important to choose the right material that suits your specific filtration needs.
When it comes to air filter materials, Aerostar MERV Pleated Air filters are made of pleated media that efficiently captures particles in the air. Trion Air Bear Filters are constructed with efficient and durable electrostatically charged fibers for maximum air filtration. On the other hand, Frost King Window Air Conditioner filters are designed for effective filtration in window air conditioning units. It’s essential to choose the right air filter material that best suits your air quality needs.
Most Commonly Used Air Filters
There are several commonly used air filters, each serving different purposes. HEPA filters are known for their high filtration efficiency, capturing small particles effectively. UV light filters use ultraviolet light to neutralize bacteria and mold in the air. Electrostatic filters use static electricity to attract and trap dust and allergens. Washable filters, as the name suggests, can be cleaned and reused, making them cost-effective. Media filters use a dense material to filter out contaminants in the air. Lastly, spun glass filters are made from fine glass fibers and are effective at catching larger particles.
