First off, every single search on Google, and on the Honeywell site for instructions on pairing was a wild goose chase. You pull up the owners manual for the HPA8350B, and you’ll get plenty of information on the operation of the purifier EXCEPT how to operate the Bluetooth function. And why should I complain about that? Because the two air filters I have constantly unpair with the app forcing me to constantly repeat the pairing process. Also, you better be within 30 feet or less of a purifier or you have no connection with it. You might as well resign yourself to manually controlling the purifier or suffer the frustration of your wasted time trying to get the app to perform reliably. Honeywell? Fire your apps development department and save yourself some salary costs.
