Sadly this is only a partial answer. I have two Ionic Breeze 3.0’s. If the filter becomes soiled beyond a certain point, the machine turns a red light on and shuts down for safety reasons. Sweeping the room while the machine is on can be enough to do this. I have learned that they simply need to be reset. Unfortunately, I have yet to learn how to do this or whether a switch could be inserted to do this without disassembling the machine. If you find out how, would you let me know? Thanks!
