Description

Advanced Filtration in Hygienic Air Handling Units

Advanced filtration is a key feature of hygienic air handling units (AHUs) that distinguishes them from conventional AHUs. Hygienic AHUs are equipped with advanced filters capable of removing particulate matter, pollutants, and bacteria from the air more effectively.

Types of advanced filters in hygienic AHUs

Primary filter

A primary filter prevents large particles such as dust from entering the air purifier. It is usually made of a wire mesh or a layer of fabric. The primary filter is usually located at the air intake of the air purifier.

Secondary filter

The secondary filter removes smaller particles such as fine dust, smoke, and hair from the air. It is usually made of a layer of paper or a layer of fabric. The secondary filter is usually located at the air outlet of the air purifier.

HEPA filter

A HEPA filter can remove airborne particles down to 0.3 microns in size. It can remove bacteria, viruses, and other small pollutants from the air. A HEPA filter is usually made of a layer of paper that is coated with a layer of fiberglass.

ULPA filter

A ULPA filter can remove airborne particles down to 0.12 microns in size. It can even remove very small airborne particles such as bacteria and viruses from the air. A ULPA filter is usually made of a layer of paper that is coated with a layer of very fine fiberglass.

Hygienic air purifiers with advanced filtration

Hygienic air purifiers with advanced filtration can be suitable for environments that require clean and healthy air, such as hospitals, clinics, laboratories, and the food industry.
