I purchased my MistAire Fall 2022. It works perfectly. The filters are easy to change. The unit is easy to clean. I use two filters at a time, meaning, while one filter completely dries, I use the second filter...switching back and forth. I also use a toothbrush, dedicated to my MistAire, to clean off the filters every few weeks which extends the life of the filters. 

I have recommended this product to others and I have also found their Customer Service Team to be very helpful when I have had questions or needed assistance.
