So far this has been amazing.  Ive ran it in all my bedrooms and living room.  The scent it puts out is subtle and smells amazing.  We have it on the lowest setting.  It takes a few seconds to review the levels in your rooms.  I love that you can see where your air levels are at.  Some rooms took a little longer to get to 100%.  We are currently running it on auto to keep it going in our living room.  I noticed dust level going down.  I definitely see some progress making our air better.   This is an amazing product and the fact that I don’t have to purchase filters every 4-6 months I love.
