What a machine!

Whatever Dyson has advertised with this machine, I can't agree to it much after seeing it work effortlessly to purify air. This is a very meticulously crafted purifier and I'm glad I purchased this. Purchased this during Feb 25, it's been kept in my bedroom and the air quality has been maintained very good. It senses the air quality, temperature and other particles and purifies it. Connectivity with the app is a great idea, it made the controls easy for me. Thanks to Dyson. You are amazing!

The fan Reinvented

Absolutely fantastic!, Dyson have done it again!… it really is the fan evolution, looks fantastic & performs exceptionally, reduces smoke pollution from the room with ease. Probably one of my best purchases since Dyson reinvented the vacuum cleaner 👌🏻👌🏻😎

Expensive but is worth it!

I bought the this one month ago and I am very happy that I did. The air filter is quiet and functions very well. The MyDyson app is easy to navigate and connects to the filter well. I used it to cool my flat during a heat wave and I am sure that it will be helpful in the winter during cold spells. The sensors detect pollution well and it provided reassurance that my indoor air is clean. It also kept my flat dust free when I was on a holiday.
