Air Hygiene Tests (Test Center for Air Hygiene)

The focus of the Air Quality Inspection Unit is on tests and tests on household appliances and other products whose use has a direct impact on the quality of indoor air. These effects primarily concern the contamination of the interior air with very small particles, ie dusts, germs (fungi, bacteria) and allergens, but also with gaseous substances such as ozone or volatile organic components (such as odourants).
In the case of these product or material tests, reductions of contamination or separation rates (for example, room air cleaners) or also emission rates are determined (e.g., vacuum cleaners).
In addition, air volume flows, pressure losses or energy consumption are also recorded.

All tests and examinations are carried out in compliance with the respective objectives of our customer according to the relevant technical test standards or in accordance with these standards. Experienced and competent personnel as well as the available measuring devices or devices (eg test rig for carrying out tests according to DIN EN 1822, test chambers, particle counters) and measuring means (eg test dusts, gases, pollen, allergens) guarantee Reliable and meaningful results.

The inspection office for air hygiene has, inter alia, Long-term experience in the determination of the air-hygienic properties and other characteristic features of the following products:

  • Vacuum cleaners (as well as vacuum cleaner bags and exhaust filters)
    Here the dust separation and emission of the devices and their filtering components are the focus of the investigations as well as the absorption capacity of the dust bags;
    The retention of germs and allergens is also of great importance.
    With robotic vacuum cleaners, a further focus is on the surface cleaning performance (navigation, dust absorption).
    Since it can be of interest for corresponding system comparisons, the user loads can optionally be determined with fine dust which occurs during the disposal of vacuum cleaner bags or during the disposal of the dust from a cyclonic vacuum cleaner.
  • Air purifiers, room air humidifiers and their filter systems
    Determination of the dust, germ, mite, pollen and odor separation as well as in the case of devices which are operated with UV emitters, ionizers or cold plasma, the ozone emission.
    In the case of devices with air humidification, a major aspect of testing is the determination of the risk of germs during the operation, with the determination of the potential germination.
  • HEPA
    Here, our test laboratory for air hygiene offers tests for filter media (MPPS determinations) accompanying standard tests according to EN 1822 for determination of the filter class (EPA, HEPA, ULPA) on prefabricated filters.
  • Mattress and bed covers
    In order to determine the suitability for house dust allergic persons, these products are tested for their air permeability and separation effect against 0.3 μm particles;
    In addition, measurements of these parameters are accompanied by measurements of the corresponding samples.

If this is desired by the customer, the performance features for marketing purposes that are proven in the device or product tests and inspections are documented in corresponding certificates and also TÜV certification marks.
