Sky is simple and powerful
I bought this looking at the efficacy of an air purifier. 0.0024 microns is spectacular and I could not find anything in stores that came even close in terms of filteration power or the number of contaminants, over 300. Opening the box was an experience. Setting up was a breeze, wheels to move around are great idea, registration and setting up the app was easy. Takes the user experience to a new level, like Tesla or Apple products.
Strongly Recommend SKY !!
