HEPA filter Applications

Biomedical

HEPA filters are critical in the prevention of the spread of airborne bacterial and viral organisms and, therefore, infection. Typically, medical use HEPA filtration systems also incorporate high-energy ultraviolet light units or panels with anti-microbial coating to kill off the live bacteria and viruses trapped by the filter media. Some of the best-rated HEPA units have an efficiency rating of 99.995%, which assures a very high level of protection against airborne disease transmission.

COVID-19

SARS‑CoV‑2 is approximately 0.125 µm. Airborne droplets of SARS-CoV-2 could be captured by HEPA filters, even if they are on the floor.

HEPA filters are widely used in the air conditioning end of clean rooms in industries such as optical electronics, LCD manufacturing, biopharmaceuticals, precision instruments, beverage and food, PCB printing, etc.
Both HEPA and super HEPA filters are used at the end of clean rooms and can be divided into the following structural forms: high efficiency with partition, high efficiency without partition, high efficiency with large air volume, super HEPA filters, etc.
