This little guy has so many things to love. It's a breeze to set up and run. The digital display takes all of the guesswork out of determining your air quality, and I love that it has the option to run on autopilot. It was very important to me that this have a "true HEPA" filter, which it does. I do think having the filtration of .2-.1 is a bit overkill, but it's still appreciated. The major plus of this is the air exchange rate. It's 500ft once per hour, but in an average bedroom, you're getting closer to 3+ exchanges, which is awesome. So far, I have been really pleased with this purifier and feel like it isn't missing any feature I would have wanted!
