Three other advantages of the electric kettle:
1. For those of us with gas stoves, we can skip the unhealthy step of burning something in our kitchen
2. The electric kettle has an automatic shutoff, which makes it a bit safer to forget about if leaving the room
3. More of the energy is going into heating the water, which means less heat goes into the room itself (don't care in winter, but I do in summer)
I love the ceiling fan idea!
I have been appreciating housefresh.com as a better place to find air purifier reviews than what makes it on Wirecutter's list.
