HEPA & ULPA Air Filters

HEPA filters, short for High Efficiency Particulate Air filters, are a type of air filter commonly used in air purifiers and HVAC systems. These filters are designed to capture and trap particles as small as 0.3 microns in size with a high efficiency rate of 99.97%.

HEPA filters are composed of a dense mat of randomly arranged fibers made of glass fibers, synthetic fibers, or a combination of both. These fibers create a maze-like structure that effectively captures microscopic particles such as dust, pollen, pet dander, mold spores, and even some bacteria and viruses.

ULPA filters are designed to remove a broad range of microscopic particles, including bacteria, viruses, pollen, and smoke particles, with an efficiency of up to 99.9995%. ULPA filters are different from HEPA (High-Efficiency Particulate Air) filters. While both types of filters are highly efficient in removing airborne particles, ULPA filters have higher particle removal efficiency than HEPA filters.

HEPA Filters vs. ULPA Filters

● Efficiency

HEPA filters are designed to remove at least 99.97% of particles that are 0.3 micrometers or larger in size. ULPA filters, on the other hand, have a higher efficiency and are capable of removing at least 99.999% of particles that are 0.12 micrometers or larger. 

● Airflow

HEPA filters tend to have a lower resistance to airflow, allowing more air to pass through. ULPA filters, due to their higher efficiency and smaller pore size, can create more resistance to airflow. This means that ULPA filters may require more powerful fans or blowers to maintain adequate airflow in a system.


Why to choose HEPA or ULPA

HEPA filters are much more broadly used in commercial applications.

ULPA filters are used in more specialized environments with strict air quality requirements, such as microelectronics manufacturing or medical laboratories, removing particulates from cleanrooms.
