Verdict

The Hoover H-Purifier 300 HHP30C011 is a smart air purifier featuring a 360-degree airflow system designed for rooms up to 100 m² with a Clean Air Delivery Rate (CADR) of 290 m³/h. Its primary characteristics include a triple-layer H-Trifilter system comprised of an outer mesh, an active carbon filter, and a HEPA H13 filter that captures 99.97% of fine particles down to 0.3 microns, alongside a specialized treatment that neutralises captured pollen. Main pros include real-time multi-sensor air monitoring (tracking PM2.5, PM10, gases, and temperature), a dedicated Carbon Monoxide (CO) alert, a ultra-quiet 21 dB sleep mode, and integrated Wi-Fi connectivity for control via the hOn app. However, notable cons include its 6.3 kg weight making it somewhat bulky to transport, a relatively loud maximum operating noise level of 49 dB at its highest speed setting, and a lack of integrated smart home ecosystems like Apple HomeKit or Matter.
