The smart air purifier impresses with its modern design and powerful performance. Thanks to its design, pollen, domestic dust, animal hair, odours, various bacteria and viruses around the air purifier are sucked in and filtered out of the air. You can lean back and relax while the air purifier decides what setting is best. Thanks to the intelligent automatic function, the LR 400 detects fine dust with a particle size of 2.5 μm and adjusts its cleaning performance to the ambient air. For better air quality and greater well-being.

Air cleaning using a three-layered filter system
Suitable for rooms up to 69 m²
How the air purifier works
Domestic dust, animal hair, odours, pollen, harmful gases and various bacteria and viruses are filtered out of the air using a three-layer filter system.
**VOC = volatile organic compounds
Our three-layer filter system with HEPA H13 filter filters out at least 95% of particles with a size of 0.02 μm (viruses are generally 0.02 – 0.3 μm in size).2) Particles ≥ 0.3 μm in size are even filtered out up to 99.95%.
In addition to the room size, the cleaning speed also plays a decisive role when choosing an air purifier. The clean air delivery rate (CADR) shows you at a glance how many cubic metres of air are purified in one hour. The higher the CADR value, the more efficient the air purifier.
2) For comparison: According to the German Federal Centre for Health Education, viruses are generally 0.02 – 0.3 µm in size (Infection control website)
***With a ceiling height of 2.4 m.
Smart Sensor – detects particles with a size of 2.5 μm
The PM 2.5 value refers to suspended fine dust particles with a diameter of up to 2.5 micrometres (for comparison: hair has a diameter of 70 micrometres).
Our air purifiers remove fine dust particles and ensure clean air.
