Beurer LR 400 air purification device

The Beurer LR 400 air purifier relies on a three-layer filtration system: a preliminary filter to remove dust, hair, and small insects, a HEPA H13 filter that captures 99.95% of particles ≥0.3 µm (and even viruses up to 0.02 µm), and an activated carbon filter to absorb gases and odors. It covers areas up to 69 m², and can be monitored and controlled via the "beurer FreshHome" app through Bluetooth and Wi-Fi. It includes 4 speeds, a quiet night mode (30 decibels), turbo mode, a timer up to 24 hours, and an LED air quality indicator. The filter change indicator alerts you after approximately 4,320 hours of operation.
