My name is Justin Williams. I am the founder and blogger at (read more about us). I was an allergy sufferer and that is also the reason why I began my trek to finding the best dehumidifier for my own personal health issues. All of the dehumidifier top picks on the site were put through their paces by Lance Perez - our dehumidifier researcher. He put each one through a series of tests to see how well they performed. Then, our editorial team compiled the insights into articles and published them.

  1. I have noticed that my house feels a lot more humid lately, and I wasn’t sure how to fix that. It sounds really nice to have a dehumidifier anywhere in the house. That way we can move it if we need to.
