Sensor seems to detect my aroma diffuser as well but definitely clears out bushfire smoke, cigarette smoke or food smell etc.
I tend to move mine around the house (my bedroom to living to kitchen) and it is a little inconvenient to move the sensor with the body. It can be used without the sensor but you always want to know the air quality so i end up moving both and having to look for another power point.
Overall very satisfied but might try a different product if i am getting another one.
