Purchased this on sale and with CashBack for use in a newborn nursery for winter. Fast delivery and very good fan and heater. Uncertain how it compares to the Hot and Cool tower with regards to the purifier and whether you can actually tell the difference. Not super loud, slightly heavy but easy to use. Turns on and heats very quickly. Have yet to wait for our first power bill.

The fan has a cool design and is easy to use. Also, I like the way it shows the graph and information on the app. It should be noted that this fan cant replace an air conditioning or a heater however it can supplement them. I do feel that air quality has improved since having it. Maybe placebo effect?

Easy to set up and has a remote that is magnetised and 'sticks' to the top of the fan, in easy reach. Using the remote you can select from cool air or heated air and the fan moves from side to side. Takes up very little space and looks stylish.

vERY happy to get this during the black friday, was like $200 off. bushfires days purifier did work and its so gentle no loud noise, we can easily have it on while sleeping with a timer, so dont have to worry about keep the A/C on for the whole night

Product is functional when it is powered on the problem is that this unit turns off after 8 hours of constant on so the monitor feature becomes void because the unit does not turn on when it detects poor air quality very poor design flaw. This feature does not have an type of override very disappointed for such an expensive unit. I purchased 2 of these to keep the air flowing and clean does not do this as advertised.

Just purchased this modern looking air purifier already noticing the huge difference with my children sleeping in a fresher air space highly recommend especially for allergies it's amazing as it also has hot and cool options .

Bought the hot and cold purifier because of the bushfires. The Pm2.5 levels outside are over 300. Inside only38. I'm not going anywhere I'm staying at home with my new best friend my Dyson. I'm scared of the long term damage of the particles. Expensive but I'm not putting a price on my health.

I’ve had the unit for a couple of years now and have used it intermittently, mostly during spring and summer months. The last couple of months I’ve used it more because of the terrible bushfires all over NSW Australia. I don’t live directly in a bushfire area at the moment. I often get crazy readings and wondering if anyone can explain it. Air quality in my area today is marked as “Hazardous”, and one look outside shows a think blanket of dirty bushfire smoke. The Dyson is reporting the outside air as “Good”, which it clearly isn’t, and inside air as “Very Poor”, which it shouldn’t be as all windows and doors have been closed in the past few hours.

There's a metallic fan in this machine that makes a grinding noise. Makes it entirely unusable overnight. Ok to use during the day, but you'll have to switch it off at night

The app gives wrong information. Current AQI in Canberra is over 200 according to ACT health but app says 90.
Also in my Canberra living room, the AQI is shown to be 0 from the moment plugged in.. I noticed AQI only raises a tiny bit when the fan is at level 1.
I'm sceptical to believe the AQI information atm.

Heats quickly. Cools as like a fan. Wont replace an air conditioner. Connected to wifi, can monitor air levels from anywhere with device, even if the machine is switched off.

The air quality is poor in my area given the recent fires in NSW. Used this for 2 hours in the room and as soon as I walked out of the room, noticed a change with the smokey smell in other portions of the house and not in the room.

This is the best Dyson has come up with. The purifying function is amazing. Fan speed is great and heats and cools a room so fast. Love the app I can use anywhere

Dual function, can be used during winter and summer. It's great for heating small spaces, but not as good in cooling spaces. Fan's power is limited. However, as all with all dyson products, its design is sleek and pleasant.

I just got my dyson am09, delivered an hour ago. I unpacked it and I set it at 20 and off it went. Great. Got to the room temp and shut off as expected, but then I notice a draft, I put the back of my hand to the heater and I can feel air coming out very very slightly. I put my ear to the base and it sounds like the motor is turning. But its very very slow. I have two fans and the other one does not do this. Do I have a faulty one ?

So I bought this for the nursery as it has temperature control function and offers both hot and cooling options. The heating function is great, it heats up the room very quickly. However I was disappointed with the temperature control function, say for example, if I wanted to control the room temp at 23 degrees I found that the room is usually about 2 degrees higher than the set temperature (that is, 25 degrees). That’s not ok for a nursery and puts baby at risk of overheating. Because of this we can’t rely on the timer function, instead we have to keep a close watch on the temperature and wake up frequently to switch it on and off.

DYSON CHAMPION
Since receiving the Dyson Pure Hot + Cool we have placed it in my sons room, as a yr 12 student he spends endless hrs in his room studying and trying to sleep . We were having a problem with the central heating going to his room, so we turned the vent off with the Dyson he has been able to maintain a comfortable environment in which to study and sleep. My son has noticed a reduction in the amount of dust in his room, as an allergy sufferer this has been very helpful.

Great product..easy to install and use it.very quite and warm the room quickly
It is great for baby room as you can set up the auto.
I would definitely buy it again
