The launch of the high-efficiency particulate air filter (HEPA) devices HFT300 and HFT600 in Europe in 2020 has rapidly met the demand for increased protection in vehicles and buildings. The main purpose of these filter devices is to protect the passengers and the operators in emergency vehicles, school buses and public transportation vehicles. The first units were primarily installed in ambulances in Germany and the U.S., as well as in public buses in the Netherlands and school buses in the U.S. The promotion of this innovative solution for private sectors such as offices, restaurants and museums has also started.

The spread of COVID-19 and the consequent increase in the global demand for protective materials required many companies to rapidly adapt, leverage their expertise and innovate. Ahlstrom-Munksjö used its long-term experience and leadership in the manufacture of filters to develop a suitable media for HEPA H14, manufactured in a compact cartridge that represents the core of the Webasto device.

The new HFT 300 and HFT 600 devices combine two main features to reduce viral loads in ambient air. They offer an extremely high virus removal efficiency thanks to HEPA H14 filters, and also generate  very high air volume flow for the rapid and complete filtration of the air every single minute.
