The Electrolux FA31-202GY Flow A3 Air Purifier provides efficient and responsive air purification for your living space. Designed for rooms up to 26 m² (approx. 280 ft²), this unit delivers a Clean Air Delivery Rate (CADR) of 203 m³/h to ensure a constant supply of fresh air. Its advanced multi-stage filtration system captures fine dust, pollutants, and common allergens, while its compact, minimalist design in a stylish grey finish complements any modern home décor.

Powerful & Adaptable Purification

The Flow A3 is engineered to respond to your environment. Its laser particle sensor assesses air quality in real-time and automatically adjusts the fan speed, ensuring optimal purification without any manual intervention. The unit's design creates a powerful yet smooth spiral of clean air that circulates efficiently throughout the room, reaching every corner.

  • Automatic Mode: Intelligently adjusts purification levels based on detected air quality (PM1.0, 2.5, and 10).
  • 360° Air Intake: Efficiently draws in polluted air from all directions for comprehensive cleaning.
  • Three-Stage Fan Speed: Manual control allows you to tailor performance to your immediate needs.

Multi-Stage Filtration for Healthier Air

Breathe easier with a filtration system that captures microscopic particles and odours. The Flow A3's multi-layer filter provides robust protection against a wide range of airborne contaminants, achieving high efficiency rates for a healthier indoor atmosphere.

  • Pre-filter: Captures larger particles like dust and pet hair.
  • HEPA 13 Filter: Removes up to 99.98% of airborne particles as small as 0.3 microns and 99.99% of common bacteria.
  • Activated Carbon Layer: Absorbs unpleasant odours, smoke, and harmful volatile organic compounds (TVOCs).

Intuitive Design & Quiet Operation

Designed with your comfort in mind, the Flow A3 features a simple touch interface for effortless control. In Sleep Mode, the purifier operates at a barely-audible 26 dB, allowing you to enjoy clean air without disturbing your rest. A colour-coded light provides an at-a-glance indication of the current air quality.

  • Ultra-Quiet Performance: Noise levels range from just 26 to 48 dB.
  • Touch Control Panel: Simple and intuitive to operate.
  • IAQ Indicator: 4-colour LED display shows real-time air quality (Good, Moderate, Poor, Very Poor).
  • Filter Replacement Indicator: Alerts you when it's time to change the filter to maintain peak performance.
