Verdict

The Soehnle Airfresh Clean Connect 500 is a smart air purifier designed for rooms up to 78 m², featuring a 4-stage cleaning system that combines a pre-filter, an EPA fine particle filter, an activated carbon filter, and switchable UV-C light to remove 99.5% of particles down to 0.3 µm. It operates with a powerful maximum airflow rate of 300 m³/h, runs on 65 watts of power, and features an integrated PM 2.5 laser sensor with a four-colour LED light ring for real-time air quality tracking. Main advantages include ECARF certification for allergy sufferers, Bluetooth connectivity for smart control via the Soehnle Connect app, a quiet 30 dB night mode, an automatic fan adjustment mode, and a long filter lifespan of up to 4,320 hours. On the downside, the device utilizes a standard EPA combination filter rather than a higher-grade HEPA H13 filter out of the box, does not support built-in air ionization, and its Bluetooth capability lacks a broader Wi-Fi range for out-of-home smart control.
