The remotes synchronized quickly upon startup and each unit showed initial high readings but these dropped to the 5-8 range within a couple of minutes. We have two pet dogs, so the house has dust and other odors. As people move around in the rooms, the sensors readings go up and then eventually down again (dust from carpets?). They are very quiet in the automatic mode, only changing to higher speeds when the sensors detect contaminants. In the night mode, only a tiny moon crescent is lit on the control panel which is great to sleep with. I am impressed with the overall quality and functions of both units.”
