    Originally only wanted the cool version. Then decided to pay the extra for heat. Happy i went with the heat. Turns out the dual use is very handy. The remote sucks but there is an app for phone.

    I love this product, There is a little required assembly but putting it together was easy and I could do it alone. I was impressed with the number of features, and the scope for customisation. Cooling-wise, the fan does work and there are 10 different speeds. Saying that, you need to crank it quite high for the hottest days, at which point I found it a bit too loud.

  • Great Fan and filter, but limited cooling ability.

    I purchased this for our sleep room at work. It gets very hot in summer and cold in winter. Have not used the heating function yet, but the cooling function does not help on reducing the room temperature. It is excellent at circulating and purifying the air.

    Dyson hits a homerun again! We own several Dyson products and will continue to purchase from the brand. This air purifier works as advertised with an exception. The air purifier works best in a single room no larger than a 400 sq. Ft space. Beyond that it has little effect. That being said, it does well in removing the smell of stale again and any unpleasant orders.
