Update... so last night turned up my machine to 7..then I started smelling a strange odor coming from the machine and heard a clunk noise ..odor disappeared once I turned the machine back down to 3 so did the noise ? So because of these reason I had to change my review ..never did I experience any of these issues with my first Dyson. My first dyson was a different size and model the heat n cold, at this point I'm not pleased at all.

Nice And Happy

Best purchase ever

Excellent

This is the fourth air purifier. One I bought for my son and the other three are in different rooms of our home. It's nice that 3 of the 4 use the same filters as I can purchase several at a time when they're on sale. Other than our bedroom I have them on auto so they monitor air quality. The app and controls are ready to use. They are quiet that sometimes I have to see if they were turned off. From low to high the airflow is evenly disributed and covers the intended area. I can tell when it's getting time to change the filter when I start seeing dust particles in the air.

The unit seems quite sensitive. I usually leave it on auto and when I was starting a fire in the fireplace it detected more particles and also when I opened the windows this spring, it detected the pollen. During both times the fan cranked up to help purify the air. The fan is quite quiet as well.

airflow is not as strong. I wish the fan was stronger.

We bought this product two months ago…working perfectly We were very satisfied with product. It working exactly how was advertised. We will highly recommend.

Great purifier and cooling air system! Now I sleep much better!

So far so good 😊. Like the app that goes with the machine . I am assuming the air quality indicators are correct . Very quiet . Easy to set up and use .
