Video: “For my birthday I got a humidifier and a de-humidifier,” comedian Steven Wright used to say. “I put them in the same room and let them fight it out.”
What would actually happen if you made a humidifier fight a dehumidifier? People have asked on Quora, Reddit, Yahoo Answers, Zendesk and Acoustic Guitar Forum. No one, it turns out, has properly tested this.
On Nickelodeon’s The Adventures of Pete & Pete, Little Pete ran a test outside, which is just sloppy science. David Letterman held an anticlimactic competition in an open studio, which is just as useless. We decided to conduct the world’s first robust test of humidifier vs. dehumidifier.
We sealed up a phone room at the Lifehacker office and turned on two machines: The MistAire Ultrasonic Cool Mist Humidifier ($US40 [$55]) and the Pro Breeze PB-02-US Electric Mini Dehumidifier ($US50 [$69]). We turned on a hygrometer to measure the humidity. Then we waited. Watch the results above.
