What we like about De'Longhi AC75

  • Operates very quietly, especially on the lowest fan speed setting
  • Cleans indoor air efficiently by removing dust, pollen, pet hair, and smoke
  • Includes a multi-stage filtration system featuring a washable pre-filter, HEPA/EPA filter, and activated carbon filter
  • Equipped with an independent ionizer to help neutralize airborne particles
  • Compact, lightweight, and narrow design makes it easy to fit and hide in small rooms
  • Provides good value for the money

What we don't like about De'Longhi AC75

  • It is an older model lacking modern features like an automatic air quality sensor or real-time display
  • The physical design can feel like just 'another extra appliance' taking up space
  • Maximum fan speeds are louder and can become noticeable during quiet hours
  • The built-in timer function is limited to a maximum of 3 hours

Verdict

The De'Longhi AC75 is a compact, 35-watt air purifier engineered for rooms up to 25 m² with a maximum airflow capacity of 140 m³/h. Its core design features a 3-stage filtration layout composed of a washable nylon pre-filter, an EPA E11 filter capturing 95% of microparticles down to 0.3 µm, and an active carbon layer alongside an independent ioniser. Main advantages include an ultra-quiet operating volume ranging from 30 to 40 dB(A), a touch-sensor control panel with a filter replacement indicator, a built-in 1-to-3-hour auto-off timer, and a lightweight 3.6 kg footprint for easy mobility. On the downside, it lacks true HEPA-grade filtration (relying instead on lower-efficiency EPA E11) and comes with a short maximum timer threshold of only 3 hours.
