I have been using this Sciaire Mini + HEPA for two weeks. I found it extremely easy to set up out of the box. Simply remove the bottom cover, take the plastic off the filter, put the filter and cover back and plug in. There is a light that indicates the air quality. Thankfully I have only had the blue light which indicates good air quality. I like that it is quiet and has sleep mode that darkens all the lights and lowers the fan speed to make it quiet. I use it in my bedroom at night then move it to the kitchen when I am cooking. I have noticed that I have less dust that settles in my bedroom. When used in the kitchen it really helps remove cooking odors. I am working from home more so using this has given me peace of mind about the air quality in my home. I recommend this product if you have any concern about the air quality in your home.
