We bought the Dyson Purifier Hot+Cool Formaldehyde 2 months ago, and I would say it's worth so far. We didn't use for heating yet, but cool function is very efficient in an interesting way. At first we thought the airflow wouldn't be enough, but actually is more than that, we only used the strongest one once. You don't feel that "wind" like the regular fan, but when you turn Dyson on after a while magically you feel the room cooler, seems like the temperature had decreased. Besides that, I noted that my hay fevers reduced significantly after start using the purifying, and we've already used it for two months and the app is saying the "filter life" is still on 95%, so its filtration is great and lasts for a while. Lasting but even matters, it is just perfect its connectivity. How you are able to control almost everything on your Dyson device only though your phone, including datas of air quality that its sensors are identifying in the room. We just love it!!!

Finally got this Dyson product I am eyeing for during my birthday this year. The white and gold color made the unit stand out on its corner. It looked classy yet modern, and the thick lower part made it look heavy duty. The heater function worked perfectly; it warmed up my bedroom in a couple of minutes. The cooling function on the other hand, helped spread and maintain the cool air inside after I switched off the AC. As it oscillates, the air was distributed evenly, no corner was left out. The air quality graph made me aware if room deodorizing and cleaning are needed. Also, seing the green line on the screen gave peace of mind as you know the air you are breathing is clean and filtered.

I bought this a in February mainly to use as a cooling fan in my sewing studio in summer but it is not as effective for cooling as hoped. As a heater in Winter it works well although I was not needing a heater so it hasn't been a successful purchase

I initially bought this as an upgrade from my original air purifier to help my child who has a rare disorder and can't process fumes properly. I didn't know that it would become a tool when experiencing myself a bad asthma, flareup due to poor installation of a new roof. That situation led to finding five spots of mold in my roof with three being toxic. We have been using it to monitor air quality in our home while all the work has been done. We've also noted that when it shows elevated levels is when my daughter is not feeling well and subject to a seizure From the fumes. I will definitely be buying a second one specifically for her use as opposed to whole home use. I could not be more impressed with the design, ease of use, functionality, and reporting system that it provides.

Happy with the air flow, don't understand the analytics display have no idea if the air filtration is happening. Ordinary people don't need graphs on thier display they need a genuine answer in words display. Eg it has displaced this amount of filtered air and this this is the result whatever that is. Simple layman's terms graphs mean nothing to me. Heat can be a bit dry but otherwise very happy. Design is stunning!
