I bought this a month ago. I am renovating my kitchen and the fumes from the glue & caulking from the countertops being installed was overpowering, turned on my Dyson and within 30 minutes the smell was gone. I have asthma and this machine is great at cleaning the air and the heat feature is nice. Haven’t used the fan yet. Also really like the app. Was able to link my machine easily and I am discovering all of its features
