Room air purifiers are still in demand for pandemic protection. However, the multitude of products on offer makes it difficult to find the right solution. The recommendation is: "6 air changes per hour and filter class EN 1822 H14". A number of suppliers, including well-known European brands for household appliances, rely on cheap OEM imported devices. Their consumer price is usually well below the 1000 EURO mark. According to our market observations, a similar but questionable filter concept can be found in many cases with imported devices. In addition to flimsy pre-filters and undersized activated carbon filters for odor filtration, filters are also used there that are referred to as HEPA and are nevertheless not suitable for virus and aerosol filtration.
We are at the start of a special year - 2024 marks the 50th anniversary of HS-Luftfilterbau GmbH. This is a milestone that underlines not only the longevity of our company, but also the innovations we have driven forward in the world of air filtration. Our journey began in 1974 when our founder, Dipl.-Ing. Harald Schuldt, decided to leave his successful career in the maritime industry to pursue new challenges. The choice fell on the then up-and-coming market of air filter technology - a decisionthat was to lay the foundation for half a century of success.
We are professionals in producing HEPA and ULPA filters for more than 40 years now. Our experience with ePTFE membrane technology reaches back more than a decade. Our latest developments in HEPA / ULPA membrane technology will take the outstanding performance from niche implementations in the microelectronic industy to wide fields of common customer applications. So far the difficulties to quality such filters in-situ with oil based aerosols is one of the main reasons why these innovative and energy saving filtertypes have not yet reached the popularity they could have.
