Panel Hepa Filter Overview and Key Features

A panel HEPA filter is a type of air purifier filter that's designed to capture 99.97% of particles as small as 0.3 microns.

These filters are made up of a series of panels that contain a HEPA (High Efficiency Particulate Air) material. HEPA material is a type of fiberglass that's been treated with a chemical to give it a positive electrostatic charge.

This electrostatic charge attracts and traps particles, allowing the air to pass through the filter clean. The panels are usually arranged in a series of layers, with each layer capturing smaller and smaller particles.

The key feature of a panel HEPA filter is its ability to capture a wide range of particles, from dust and pollen to bacteria and viruses.

ULPA filters are designed to remove airborne particulates with exceptional efficiency, capturing particles as small as 0.1–0.2 micrometers in diameter with a minimum efficiency of 99.9995%. They are typically used in environments that demand stringent air purity, such as semiconductor manufacturing, pharmaceutical production, and high-grade cleanrooms.

ULPA filters are rated as U15 to U17 according to the EN1822 standard, with U15 filters capturing ≥ 99.9995% of particles ≥0.12 µm, U16 capturing ≥ 99.99995%, and U17 capturing ≥ 99.999995%.

In comparison, HEPA filters have an efficiency rating of 99.97% at 0.3µ, whereas ULPA media has an efficiency rating in excess of 99.999% at 0.12µ. This makes ULPA filters a better choice for applications where extremely high levels of air purity are required.

ULPA filters are available in various configurations, including cylindrical cartridge filters, conical filters, and panel filter configurations. They are constructed from layers of pleated filter media and carbon steel inner and outer cores for durability.

Here are the key differences between ULPA and HEPA filters:

ULPA filters are essential in environments where even the slightest airborne contamination can lead to significant product or process failure, such as cleanrooms, medical facilities, and laboratory environments.

Panel HEPA filters are designed to provide high levels of air purification, with HEPA media rated at 0.3µ at 99.97% in gaseous flow. This makes them ideal for a variety of industrial and commercial applications.

The media is available in pleat depths ranging from 0.625″ to 6.0″, giving you flexibility in choosing the right size for your needs. You can also choose from a variety of endcap, seal, or frame options, including polyurethane or silicone molded seals and metal end caps.

Some panel HEPA filters are self-supporting, while others may require inner and outer cores made from perforated carbon steel, galvanized expanded steel, or stainless steel options. Flame retardant options are also available for added safety.

ULPA and ASHRAE filters are designed to improve air quality and eliminate particulate matter like smoke, pollen, dust mites, and dander by trapping particles without much restriction to the airflow.

ULPA filters have an efficiency rating in excess of 99.999% at 0.12µ, making them ideal for clean-room applications and environments where air purity is non-negotiable.
