You can pretty much assume that if your simple fan+filter has a screen, Bluetooth, wifi, an app, and proprietary filter media that it's going to have some means of vendor locking the user. Let's face it, that's the goal behind all of this stuff. To give you a pathway to purchase more products and generate brand awareness and engagement.
