Excellent company and I have been using their products since the early kickstarter days.
Friends have tried many cheaper imitations but they last for a fraction of the time and often die after a single season, costing more in the long run. All of my Evapolar products (I have about 5 now) are still running years on and the cartridges last about a year or more.
I use Evapolar at office: it sits next to my pc screen and grants me a very pleasing bubble of fresh and clean air around my desk. It's effective, easy to use and totally silent. I love it.
"personal climate" is a great descriptor for this; as a person who really dislikes AC but doesn't want to roast to death in the dry LA heat this is the perfect solution! Small, portable and effective!
I first found out about Evapolar from an unboxing video on YouTube. I liked the concept and decided to order one. That is now 3 years ago, and I am on my second device. I decided to upgrade to the EvaSmart, as its got WIFI and a few other features. I use it daily when I go to sleep and truly enjoy the fresh air it provides. My first device is in my office and it works it magic on hot summer days.
