Indoor air filters with filter function against viruses were rather rare before the Corona pandemic. With the new Airpura UV-614 air purifier, we have responded to the requirements of a changed health policy and created a filter system that detects even aerosols – particles that can be smaller than a micrometer. Conventional filters, for example, only had to collect allergy-causing pollen, which is many times larger than corona particles in the room air.
In addition to standard coarse dirt filters, the Airpura system therefore also contains so-called HEPA filters (High Efficiency Particulate Air-Arrestance), which absorb up to 99.995 percent of the potentially virus-contaminated aerosols in a four-stage filtration. These filters are also known as Ultra Low Penetration Air (ULPA) filters. Viruses, fungi or bacteria retained by the filters are eliminated by irradiation by thebuilt-in 20-watt UV lamps.
