Based on our long-standing and extensive expertise and more than 60 years' experience in filtration, we develop tailor-made and innovative filtration solutions together with you. Our wide range of particle and gas filters for fresh-air (residential) ventilation systems with and without cross-flow heat exchangers keep harmful substances from entering the home while also meeting energy efficiency requirements.
Many different factors necessitate the use of a fresh-air filtration system:
- Airborne particles such as PM 2.5 and (ultra-)fine particles as well as allergens
- Household contaminant loads caused by emissions from furniture, flooring and paint
- NOx,SOx,H₂S, Cl₂, NH3, odors and other gaseous pollutants in the ambient air
We provide you with individually one-stop solutions including HEPA filters, gas phase filters, combifilters and anti-allergy filters.
The air filters used in stationary filtration system are the key elements for removing the various air pollutants and harmful gases.
Our filters meet the highest requirements of various national and international standards, including Chinese standard GB/T 18801:2015, ANSI/AHAM AC-1:2013 and Japanese standard JEM 1467:2013 as well as different industrial standards like EN 779, ISO 16890, EN 1822 and ASHRAE 52.2.
We have developed a specific product range to address the formaldehyde challenge in homes, including an impregnated, pleatable carbon medium that we manufacture ourselves. The carbon medium is an ideal combination of gas-phase filtration and particulate filtration in one filter for PM10, PM2.5, formaldehyde, TVOCs, ammonia, odors, etc. A nanosilver-free biofunctional layer can be integrated on request to provide triple protection against household air pollutants and contaminants.
In-house production and patented technologies
We purchase high-quality raw materials and manufacture all our particle, activated-carbon and combifilter media in-house. These are then converted into filter elements, in some cases using patented technologies. We are also able to manufacture support housings for our filter elements. Thanks to this high development and production penetration, we ensure that the very latest state-of-the-art technologies are always incorporated in product optimization.
Quality management system per IAFT 16949
Our quality management system in accordance with IAFT 16949 provides a secure underpinning for all operations, from the initial development through delivery of the series-manufactured products to after-sales service. We also meet any other requirements you may have, such as specific quality standards drawn up by you or your country.
Rigorous testing processes worldwide
It is vital to design components to ensure optimum filter area loading and filter lifetime in the specified purifier installation space even under the toughest of conditions. Our filters are designed and developed using state-of-the-art testing technology.
We subject our filters to rigorous testing in channels that conform to DIN 71460-1. Besides the standard tests in accordance with the DIN standard, each filter is also subjected to our own specific tests. These include exposing the filter to atmospheric dust, synthetic fine dust, temperature and moisture stress, and much, much more.
Global research and development capability
We are solidly backed by the Freudenberg Technology Unit, which focuses on the research and development of market-leading technologies. Globally, we have more than 60 experts in various fields, including filter selection, design and testing. You have exclusive access to our six modern laboratories and testing outlets located in Germany, the United States, South Korea, China and Africa.
