Energy Efficient Design

The effective utilization of resources and the sustainable use of our environment are a requirement of our time. HS-Luftfilterbau GmbH stirves to optimzie it's ISO 14001 certified production by the useage of innovative materials and to increase the energy efficiency of our products. Most of our prodcuts haven proven in the field that high filtration efficiency does not exclude a reduction of the operational costs.


HS Luftfilterbau supplies uncompromising quality. This is what our customers expect from us. Therefore, HS Luftfilterbau GmbH implemented a highly effective quality and environmental management system. Continuous improvement processes are part of our company culture and ensure that all processes lead to satisfaction of the concerning parties. Our core ideals are founded on our ISO 9001 & ISO 14001 and KTA 1401 cerzified quality assurance system.

Cleanroom / Pharma / Medical

The latest production processes e.g. in the microelectronics and pharmaceutical industries require highest degrees of purity of the environment. HS-Luftfilterbau GmbH operates ultramodern production and test facilities for HEPA, ULPA and molecular filters to maintain clean and sterile enviroments. All our products are intensively tested according to internationals standards before leaving our factory.

HVAC / Ventilation

Clean air and healthy climate affect the well being of people. HS Luftfilterbau GmbH offers a comprehensive range of high quality air filters ensure optimum ventilation of working, residential, commercial and office spaces. A careful choice of materials guarantees energy and economic efficiency.


Relaunch of our website06.2012

HS Luftfilterbau GmbH has 38 years experience in the field of filter technology. This renders us some kind of a veteran in the filter market but we still regard ourselves as manufacturer of highly innovative filter systems.

During this long period we have beside the production of conventional standard products also developed countless customized special solutions designed for different applications.

Back in 1996 our website was one of the first in the german filter market. Moreover, we were the first German manufacturer who made all it's filter product information availabele on the Internet without any restrictions before other's even saw the potential of the global network.

It is always our aim to provide good and easy to understand information about our products and filter technology. For this claim, we have formulated in early 2012, the goal of a complete modernization of our site. In particular, the scalability of the information presented to our users was of great importance to reduce the informational overload some viewer's might have experienced with our former  design.

Our thanks to the pioneering implementation of our vision goes to:

Informationen aus dem PDF zur Normrevision:

The dispute of the italian Uni against the changes to EN779 was settled by end of March 2012. The revision of the standard EN779:2012 will be valid as EN standard very soon.

The essential modifications are:

  • minimum efficiency for filter of class “F” at their (electrostatic) unloaded state (M.E.)

  • new classification M5 and M6 instead of F5 and F6

  • leak tests for assessing the level of efficiency (0.4 µm), the aerosol DEHS (Di-Ethyl-Hexyl-Sebacat) is to be used as a standard procedure.

The classification in compliance with  EN779:2012 divides filter into Group-G and Group-F filter for coarse and fine dust adsoption. Accordingly, in the future there will be three filtration efficiency levels – G, M, and F. Filter that state a filtration efficiency for particles of 0.4 µm of 40 percent or less will be marked as class G.

The categorization of filtration Group G (G1 – G4) is based on the average dust holding capacity (gravimetric / weight). As for Group F and M, the determination of dust holding capacity will be an indicator for the filters lifespan. It won‘t be used for classification matters. Group M will include all filter with an average filtration efficiency of 40 percent of higher but with an efficiency of 80 percent or less for particles of 0.4 microns. Therefore, class F5 and F6 will fall by the wayside. Class M5 and M6 are to replace them. Other than that, the efficiency levels will be the same. Filter with an efficiency of 80 percent or higher for particles of 0.4 microns will be marked as Group F. Their overall efficiency is to be determined as before. But, according to the new procedure Group F-filter are to uphold a “minimum efficiency” (short: M.E.) which indicates the primary efficiency at the state of being electrostatically discharged This will be a mandatory criteria for all Group F-filter. We predict that for most commonly used synthetic filter media this will be hard to achieve.
