Runs quietly. Has stopped my sinus problems as I have it in bedroom

Early days but I am very pleased with its operation

It was a good product, but wasn't what I was told I was getting, it didn't have have phone connectivity, so I couldn't track the data online like I was told. I called Dyson and they said that this product never had connectivity, but it turned out that the good guys had been steered up the garden path by Dyson, so they happily exchanged it for another model. Good Guys were helpful but I felt a bit like id been deceived by Dyson.

I purchased this to replace an old kambrook tower fan that was blowing dust and whatever else into my childrens nostrils n all over their bedroom ( even on the walls) yuck. The Dyson purifier is the best, so silent, I could tell it was working from day 1, my son who has asthma and a hay fever sufferer stopped most of allergy symptoms. Now am saving up to purchase a smaller one for the guest bedroom and dispose of the last tower horrid fan in our home.

This product is fantastic! Highly recommended
