In enclosed spaces, central air conditioning systems circulate air using a recirculation method. Therefore, particles released into the ambient air through actions like coughing, sneezing, talking, and breathing spread, increasing the risk of respiratory transmission to humans.

Hifyber's multi-layered, pleated "Nanofiber Filter Media" improves the filtration efficiency of filters used in air handling units, resulting in energy savings.

Manufactured in accordance with international test standards such as EN779:2012, ISO 16890, and ASHRAE 52.2, HIFYBER filter media has different efficiency classes from F7 to E12 and Merv8 to Merv16. Furthermore, with its stable mechanical filtration feature compliant with ASHRAE 52.2 Annex J standards, it offers more reliable indoor air quality compared to other products providing conventional electrostatic filtration.
