Beurer LR 500 air purifier ensures that the air you breathe at home is clean by filtering out a large number of airborne viruses and bacteria. This gives you clean air within your own four walls. Air cleaning using a three-layered filter system (prefilter + activated carbon filter + HEPA filter): domestic dust, animal hair, odours, pollen, various bacteria and viruses as well as harmful gases are filtered from the air. Tests show that the three-layered filter system with HEPA H13 filter filters out up to 95% of particles = 0.02 µm in size (IUTA test in April 2020 according to DIN 71460-1)*. 99.95% of particles = 0.3 µm in size are eliminated.
