What we like about De'Longhi AC 100

  • Highly effective multi-stage filtration system that noticeably cleans the air, leaving rooms feeling fresher.
  • Operates very quietly on lower fan settings, making it suitable for bedroom use during the night.
  • User-friendly design featuring a lightweight build and an intuitive, easy-to-use touch control panel.
  • Useful built-in convenience features including an independently controlled ionizer and an auto-shutoff timer.

What we don't like about De'Longhi AC 100

  • Filter durability is a common point of dissatisfaction, with users noting that filters need frequent replacement.
  • Noise levels increase significantly when operating at the maximum fan speed.
  • Ongoing maintenance costs can become high due to the regular replacement schedule of the 2-in-1 HEPA and carbon filters.

Verdict

The De'Longhi AC 100 is a floor-standing 40-watt air purifier designed for rooms up to 40m², delivering an airflow rate of 70, 100, or 130 m³/h depending on the selected setting. Its core strength lies in a multi-stage filtration system combining a washable pre-filter, a certified HEPA filter targeting particles down to 0.3 microns, an active carbon filter for gases and odours, and an independently controlled ioniser. Key advantages include its flexible three-speed fan control, an automatic 1-to-8-hour auto-off timer, a dedicated LED filter replacement indicator, and a relatively quiet operation range between 33 and 44 dB(A). However, its limitations include a relatively low Clean Air Delivery Rate (CADR) for larger open-plan spaces, measuring at 114 for smoke, 132 for dust, and 121 for pollen, which reduces its effective coverage to just 10m² during highly intense air recycling cycles.
