    It's a great product, I have a 50 sqft office that due to some designing flaw lacked heating in the winter. I used to struggle during the winter, it was either too hot with some space heater, or too cold without it. Now with this very smart(and safe) heater I work in my office with no issue. Only reminder to some people is that it draw quite some power, and my curcuit did not take it too well. You might want to make sure the space has enough power so it won't trip.

    The product is good , but the price was still too high when I caught it on sale . I am hopeful that I will see the best reason I brought it come to my view. I have seasonal allergies ( use over the counter medication and prescription when needed) and thus far it is good but so expensive for the middle class who probably use it more .

    package arrived very well. no damage. it was well packed. dyson quality is really out standing. filter installing was very easy. must install dynos link app. you can control cooling, heating, order filters and connect to support right from the app. very useful. dyson HP09 is very quiet on auto setting. I like that it purifies and can be use as a fan or a heater in winter. another thing which is different in this dyson HP09 is you can set temperature control when using as a fan at cool or heat and it really gives cooler air. can not tell much about the heating function as of now. overall I really like it.

    I had this product for about 3 weeks now. So far, I really like all the duties of this purifier. The other day I had a headache and wasn’t sure why. I had turned the purifier off the day before. I went to lay down and I decided to turn on purifier, which indicated the pm levels were very high. I let the purifier run and air quality retuned to normal.

    This year has been all about health management and recovery. I know air is one of the most important nutrients our bodies need and I’m confident this air purifier helps. Love the interface and app! It’d be cool if they linked the data between the vacuum and air purifier though. Maybe in a future update. I definitely recommend this product.

    Efficient heater, so-so as a cooling fan

    This is my second Dyson unit; I got this one for heating my office, which is at the opposite end of the house from where the air conditioner (sorry—"ductless heat pump") is located. As a heater, it is very efficient—a huge improvement from the inexpensive portable heater I'd been using. It's not as efficient for cooling, but that wasn't the main thing I bought it for. (And it's not hard to swap the units twice a year.) As with my other Dyson, it does a good job of maintaining indoor air quality. Based on the remaining filter life display, the filter probably won't last as long, but should still be good for the intended 12 months.
