The DeLonghi AC 75 is suitable for room sizes up to 25 m² and provides an air circulation of up to 140 m³/h. Therefore, the air purifier is absolutely sufficient for a standard-sized room. The energy consumption is around 35 watts at the highest ventilation level, which is still reasonable. With a relatively low weight of 5 kg, the device can be easily carried to another room and used as needed. The purifier also features a switchable ionizer, which generates ozone and neutralizes airborne dust particles, pollen, exhaust gases, or smoke.
