Hifyber, an Abalioğlu Holding company that offers high efficiency filtration applications with nanofiber coated antibacterial-antiviral filter fabric for HVAC systems, stresses filtration efficiency of air filters used in HVAC systems.

Indoor air quality is among the factors having a negative impact on quality of life in collective living spaces. Particularly in spaces shared by a large number of people simultaneously such as offices, businesses and industrial facilities, indoor air quality has a direct impact on both people’s health and employee performance.

The Covid-19 pandemic has once again revealed the importance of air quality in indoor spaces. As companies which had adopted a work from home model since the first months of 2020 began to gradually return to offices thanks to ever higher rates of vaccination, the issue of correct use of air filters became a talking point once again.

Air filters offer an effective solution to eliminate microorganisms, dust and allergens contained in indoor air of buildings and industrial facilities and create safe living spaces for building occupants. Air filters used in HVAC systems provide the first line of defense against pollutants such as bacteria and viruses in the environment.

The Ashrea 52.2 standard
Experts draw attention to filtration efficiency of air filters used in HVAC systems. Filtration efficiency measures the extent to which filters eliminate particles from the air. The Ashrea 52.2 standard is among the most widely recognized standards used to assess filtration efficiency. However, one needs to also comprehend some basic information regarding the type of media used in filters to better understand the operational performance of the filter.

The ASHRAE 52.2 standard Appendix J
Air filters are grouped under two main headings, mechanical and electrostatic filtration, with their efficiency being assessed separately. This is because while mechanical filtration offers constant filtration efficiency, electrostatic filtration provides high filtration efficiency during initial tests but filtration efficiency in the latter is reduced in the course of active operation. Therefore choosing filters solutions that conform to the ASHRAE 52.2 Appendix J standard is of vital importance.

Longer Economic Life of Filters Through Nanofiber Filter Media
Nanofiber filters for mechanical filtration provide high performance both in the beginning and in the course of filter operation. The nanofiber coated antibacterial-antiviral filter fabric employed in the “Nanofiber Filter Media” developed by Hifyber ensures healthy air conditioning in HVAC systems. Nanofibers improve filter efficiency without any significant increase in filter pressure drop, ensuring extended filter economic life and cleaner air input.

No loss of efficiency is observed in the Hifyber Nanofiber HVAC Filter Media that has also been tested in accordance with the rigorous industrial filter conditioning standard, ASHRAE 52.2: 2007 Appendix J.
