Save money and buy cheaper, app, WiFi and Alexa skill are useless App does not log in in half the time and expires, Alexa skill does not recognize the device, I have it in renamed very simple names like Bedroom, Pure, Kitchen and even Fan. I managed to change the setting on the device once. Hardward (fan, filter and UV lamp are almost the same on non-wifi devices, don't waste your money. It will definitely be returned.
