We spend about 90% of our time indoors. Thus, the primary concern for the use of a ventilation and air conditioning unit is to provide healthy and comfortable indoor air quality. In addition to temperature and humidity, this is primarily determined by the quality of the outside air filtration. Today, fine dust pollution in the industrialized world dictates the necessary quality of outdoor air filtration. In order to ensure the demand for good indoor air, a new and better classification system for filters has been introduced with the new filter standard DIN EN ISO 16890.

Depending on the place and purpose of use, the filters in HANSA air-conditioning units are installed in accordance with this standard. Here, in addition to the necessary filter quality, the energy aspect is also taken into account, since the filter operating costs are far higher than the filter acquisition costs. In addition to pocket filters in various pocket lengths, compact filters and panel filters are also used. Other solutions such as activated carbon filters or terminal H-class filters are also included in the product range.
