Your air conditioner may already be connected to the web, but what about that lowly air purifier gallantly battling dust in the corner? If a completely connected home is on the docket, prep your 270 bucks and get ready for an upgrade. Honeywell's latest air purifier includes integrated Bluetooth, letting you use your Android or iOS smartphone to turn the device on when you enter the room, control cleaning levels, set a schedule and track when it's time to swap out the HEPA filter. But it takes automation even further, pulling pollen and mold alerts from the web via your smartphone and adjusting fan levels automatically. The HPA250B, which can accommodate rooms of up to 310 square feet, is available from Best Buy for $269.99.
