When we first set up the NR MAX, it worked great and then it stopped working a few days later. We received an error that the water level was low, but there was plenty of water in there. After recleaning/resetting up a few times, we reached out to Customer Service. However, we didn't receive any correspondence. We finally reached out the Instagram account via DM and received a swift response. Miro sent us a new fan and everything has been working great since then! We love that it's so easy to clean, and the humidity sensor works great!
