What we like about Electrolux FA31-201GY

  • Compact and space-saving design
  • Lightweight and easy to move between rooms
  • Intuitive touch-based user interface
  • Effective multi-stage filtration for dust, allergens, and odors
  • Efficient air circulation via its spiral vortex outlet
  • Very quiet operation when running in Sleep Mode
  • Helpful real-time air quality indicators and filter-change alerts
  • Responsive Auto Mode that adjusts automatically to pollution levels

What we don't like about Electrolux FA31-201GY

  • Lacks smart features such as Wi-Fi connectivity, app integration, or voice control
  • High noise levels and a loud fan sound when running at maximum speed
  • Some users report an annoying, alternating whistling tone while operating in Night Mode
  • Recurring costs due to non-washable filters requiring periodic replacement
  • Limited coverage area that is strictly optimized only for small or medium-sized rooms

Verdict

The Electrolux Flow A3 (FA31-201GY) is a compact, floor-standing air purifier engineered for smaller rooms up to 40 m², utilizing a 4-stage filtration system that includes a cylindrical pre-filter, an antibacterial coating, an EPA12/HEPA 13 filter, and an active carbon filter to capture micro-dust (PM 2.5), odours, and up to 99.99% of airborne particles as small as 0.3 micrometres. Operating on a 20W motor with 3 fan speeds, it features a smoke Clean Air Delivery Rate (CADR) of 180 m³/h, a spiral air outlet for uniform circulation, a laser particle sensor with a multi-coloured PureSense air quality display, and an intuitive touch UI. Main advantages include its whisper-quiet performance in sleep mode at just 26 dB(A) (maxing out at 49 dB(A)), efficient automated performance adjustments via Auto Mode, and a lightweight 2.5 kg frame for easy portability. However, its downsides include an absence of advanced smart connectivity or a dedicated mobile app for this specific model, tight air inlets at the bottom that can potentially limit intake over time, and relatively expensive replacement filters that need swapping every 12 months.
