In the course of their life, a person will spend several years in the car – an important reason to ensure well-balanced and good quality air in the vehicle. In-cabin air filters have been around for decades – for 30 of those years we have been working with manufacturers, and consequently know their requirements in detail. Our technology has grown over the decades to both meet and keep pace with the changing customer demands in the industry. That’s why you can rely on the products from our company to feature innovative technology and meet the highest requirements, whether they are test stands or measuring instruments for validating air filters.
We place the same demands on the interior climate in motor vehicles as we do on the climate inside buildings. The same applies to cabin air filters, which are now found in every vehicle. From the former pure “pollen filter” to the later relevant separation of fine particles such as soot or dust to gas filtration, the expectations placed on air filters, both by manufacturers and society, are now comparable to those of air conditioning systems. These are the fields in which you operate and your customers, the producers of all types of motor vehicles, expect impeccable cabin air filters from you? As a test institute for quality assurance in filter production or in the field of motor vehicles you are responsible for proving that filter media are effective without restriction? Or do you work in research and test filter media and materials in order to further develop and optimise them? Then you have come to the right place. Topas system solutions test cabin filters as quality control or production-accompanying in defined sampling intervals. We offer these technologies to filter and filter media manufacturers as well as to testing institutes.

Current trends in the development of filters and separators in the automotive industry and their quality-oriented testing place high demands on standard-compliant and automated testing technology, which we successfully meet with our wide range of filtration testing equipment. Topas test systems are state of the art and measure the separation performance of cabin air filters against particles and gases individually or in combination.
Testing routines for the evaluation of particle separation
- Differential pressure test
- Gravimetric separation efficiency test
- Dust loading capacity
- Measurement of fractional collection efficiency
- Determination of PMx-based collection efficiency
Our software to easily handle testing equipment
The PAFWin test system control and data acquisition & evaluation software, developed by Topas and running under Windows, ensures that the handling of test equipment and the performance of accurate and reproducible tests remains easy. Contact us for an exact specification of which additional devices and test sequences PAFWin supports with its software components.
Our testing systems in the application area of cabin interior filters comply with relevant standards and guidelines, such as DIN 71460-1/2 (draft) and ISO/TS 11155-1/2.
