Enhancing Clean Air with PEPA-F™

Pathogen and Particulate Filtration

Trademarked and Patented Filtration Technology



Our PEPA-F™ filters for heating, ventilation, and air conditioning (HVAC) systems are a smart and efficient solution for buses, railways, and buildings that are immediately available.


Based on a modular concept allowing for an optional antiviral coating, the filter improves air quality and ensures fine filtration with minimal integration impact on HVAC systems. The filter not only captures virus carriers but can also eliminate the virus, making our air filtration  solution unique in the market.


All PEPA-F™ filters feature various post-treatment options, including high flame-retardancy compliance with EN45545-2, ISO3795, and FMVSS302. Our filter media offers superior resistance to chemicals, solvents, UV, temperature, and ageing.

How is the filter composed?


It is a multi-laminated filter with a foam base layer and additional media layers, such as:

Arrow depicts airflow passing through the filter, with particles being trapped and deactivated to illustrate improved air quality throughout the filter’s lifespan.

Smart and efficient solution for transportation and buildings


The modular multi-layer design uses the latest media technology, allowing you to achieve optimum performance, from coarse to fine filtration, based on the operator’s needs.


In addition, an optional special impregnation consistently captures and kills viruses and bacteria throughout the filter’s lifespan.


It follows a two-step approach:


First, the filter captures virus carriers, such as water, dust, and aerosols.
