The ONSON Smart Air Purifier is a Wi-Fi-connected HEPA purifier aimed at pet owners and allergy sufferers. It pairs a three-stage filter with an H13 True HEPA element, a PM2.5 sensor and a four-color air quality light, and it works with Alexa, Google Assistant and the Smart Life app. Five fan speeds, an auto mode and a 22 dB sleep mode with the lights off cover day and night use. Against rivals in its class it leans on app and voice control and a real-time air quality readout rather than on a washable pre-filter or a long warranty.
