The Menred Smart Ventilator features a highly user-oriented design. Self-explanatory icons in the matte white front make for intuitive operation. The elegantly curved bow at the top is both a characteristic design feature and practical at the same time: with its help, the air purifier can be quickly and safely opened for replacing the filter. With a consumption of 1 kWh in ten days, the device is environmentally friendly and low in power consumption.
