Verdict

The Philips 800 Series AC0820/30 is a compact, 2.3 kg air purifier designed for small rooms up to 49 m², operating on 22W of power with a 1.6 m power cord. It features a NanoProtect HEPA filter that captures 99.5% of ultra-fine particles as small as 0.003 microns, delivering a Clean Air Delivery Rate (CADR) of 190 m³/h. Key advantages include an intelligent auto-purification mode driven by a PM2.5 sensor, a real-time 4-colour air quality light ring, and a whisper-quiet sleep setting that drops noise levels down to 19 dB while dimming the display lights. However, notable drawbacks include the lack of a carbon element in the standard filter for advanced gas and odour removal, the absence of smart app control or a built-in timer, and a loud 61 dB noise level when operating on its maximum turbo mode.
