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.
