Pleased
Had the air purifier for a while now and it works well in my view, only slight issue was that it came with a flat battery in the remote control, once replaced seems good now.

Good purchase
I bought this product almost 10 months back for my newly born baby. Since we don't have any A/c or heater in our room. It was summer time about to finish and after that winter started. So I did used in two different seasons. It was really good decision to get this product. Works well and never had any problem and even I didn't see it consuming lot of power. I do recommend this product if someone wants to use just one product for summer and winter.

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!

Great air purifier
Very happy about this air purifier! I bought three in a month for different rooms! The hot air is definitely a plus. The APP is super user-friendly as well. Overall, a very useful air purifier.

Helped reduce allergies from pollen and dust!
Bought two of these for our living room and the other for our office room. Love the air filtration and how easy you can manage the settings through the Dyson app. It stays on for most of the day, and we noticed how it helped with reducing our allergic reactions against pollen and dust.

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.

Great features, amazing devide.
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!!!

Two Performances in One Classy Unit
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.

Poor Cooling
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

Great surprise his tool for preventing seizures
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.

Display info needs improvement
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!
