Verdict

The De'Longhi AC230 is an 80W air purifier designed for medium to large spaces up to 80m³, delivering an airflow rate between 110 and 255 m³/h and CADR ratings around 235 for smoke, dust, and pollen. It features an integrated Air Quality System (AQS) with gas and odour sensors that display real-time conditions via colour-changing LEDs, an independently controlled ioniser, and a comprehensive 5-stage filtration setup comprising a washable pre-filter, a HEPA filter capturing particles down to 0.3 microns, an active carbon layer, a Nano Silver antimicrobial filter, and a titanium dioxide (TiO2) photo-catalyst filter paired with a UVC lamp. Main advantages include its highly effective multi-layered filtration, an automatic mode that dynamically adjusts the 3-speed fan based on pollution levels, user-friendly touch controls, a programmable timer (up to 8 hours), a filter replacement alert, and a relatively quiet operation spanning 33 to 50 dB. However, notable drawbacks include its higher energy consumption at maximum speeds compared to smaller units, the regular long-term cost of mandatory filter replacements, a lack of modern smart app or Wi-Fi integration, and a bottom cable storage compartment cover that awkwardly uses protruding screws.
