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.
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.

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:
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.
