The BRAUN AC7031 SensonAir Air Purifier is an efficient and intelligent solution for improving indoor air quality. Designed to cover areas up to 42m² (approx. 452 ft²), this unit boasts a Clean Air Delivery Rate (CADR) of 301 m³/h for particulate matter and 130 m³/h for formaldehyde. Its advanced filtration system and smart sensor technology work together to automatically detect and capture airborne pollutants, ensuring a healthier and more comfortable living environment.

Advanced Triple-Filtration System

The AC7031 employs a multi-stage filtration process to effectively clean the air, capturing up to 99.9% of ultrafine particles as small as 0.3 microns.

  • Pre-Filter: Captures large particles like dust, hair, and pet dander, extending the life of the main filters.
  • HEPA Filter: Removes fine particles such as pollen, allergens, smoke, and bacteria.
  • Activated Carbon Filter: Absorbs and neutralises common household odours, volatile organic compounds (VOCs), and other harmful gases.

Intelligent SensorAir™ Technology

Equipped with Braun's innovative SensorAir™ technology, the purifier features a smart particle sensor that continuously monitors the room's air quality. In Auto Mode, it automatically adjusts the fan speed based on the level of pollutants detected. A simple, colour-coded light indicator (blue, yellow, orange, and red) provides a clear, real-time visual of your indoor air quality.

Key Features & Benefits

  • High-Efficiency Purification: Delivers a high CADR for fast and effective air cleaning.
  • Smart Auto Mode: Automatically adjusts settings for optimal performance and energy efficiency.
  • Quiet Operation: Operates at a low noise level of just 45dB on its lowest setting, perfect for bedrooms and living spaces.
