Webasto air-conditioning systems ensure pleasant interior temperatures even in hot climates. Optimum air distribution, pleasant coolness and low humidity are guaranteed. Thanks to a large selection of devices and accessories, we supply individually tailored solutions. If you want to rid the indoor air of particles smaller than 0.3 micrometers, such as respirable viruses, bacteria, aerosols or dust, you can rely on the Webasto HEPA filters (H14). They meet international standards and are very easy to install and replace.

Filter systems for buses

Webasto filter systems for vehicle interiors clean 5 to 10m³ of air per minute of particles smaller than 0.3 micrometers, such as respirable viruses, bacteria, aerosols or dust. They therefore fulfill HEPA filter class H14 as well as the international HEPA filter standards WHO /CDC/ ECDC. The degree of purification corresponds to 99.995 percent. For vehicle interiors of different sizes, there are variants with a length of 60 or 120 cm, which decontaminate 300 or 600 cubic meters of air per hour. Several air filters can be combined for larger spaces. The filter systems require a 12-volt or 24-volt connection and can be retrofitted quickly and easily. The filters can be changed without contamination.

Key facts

  • 99.995 percent purification level
  • HEPA filter class H14
  • Complies with WHO /CDC/ ECDC standards
  • Available in various sizes
  • Simple installation
  • Contamination-free filter change
