LEVOIT Core 400S Smart Air Purifier, True HEPA, CADR 400 m3/h up to 83 m2, PM2.5 display, app and Alexa

This is the big Levoit, it handles a room of up to 83 m2 so it works for a living room or an open-plan flat, not just a bedroom. It shows the live PM2.5 number on the top, sets its own speed in Auto mode, and on the sleep setting it runs at 24 dB, which is quiet enough that I forget it is on. Unlike my smaller purifier you can control this one from your phone with the VeSync app or by voice with Alexa or Google, and it has a timer and a child lock. It is 52 cm tall and about 6 kg so it travels fine in a car. I bought it in September 2025 and hardly used it, so it is close to new. Same model new: amazon.es/-/en/dp/B08R794ZMX
