I am using Vornado air purifiers, but I don't have air quality monitoring yet and don't care about WiFi features. The higher end Vornados have monitoring built-in, but it is rudimentary and just a light bar. Without air monitors to check them, it's hard to tell, but they seem to work quite well. Vornado excels at producing room-sized torrents that direct air through its filters. We blew out a candle once and the smoke visibly made a beeline towards the Vornado.
