Since we've had this purifier the air is better, and my wife's allergies have subsided. I downloaded the Dyson app and set it up from there. I keep the fan on number 7 and it is very quiet. Through the app, you can see if the filter needs changing also. Perfect !!
Now that I have 2 of this in my house together with the other Holmes purifier that I have, I know that the air in my house will be cleaner. I'm looking forward to using this on the coming more years to come. This will really help me control my allergies.
