Humidifier vs Dehumidifier

Nick Douglas locked the Amazon-bestselling MistAire humidifier and Pro Breeze dehumidifier in a sealed booth together, then forced them to fight like dogs and cockerels.

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.

Spoiler: small portable dehumidifiers are useless.
