Clean air at home
I suffer from on going sinus issues, worsened by poor air quality in the home. Since using the Dyson air purifier, I have found my allergies have greatly improved. I have also appreciated the temperature control feature with this product.

I thought I would provide a 2nd update review after 2 months of use, basically, this little unit has replaced our reverse cycle airconditioner in our bedroom which is about 30 square metres in an old 1880's terrace house yes, we have roof insulation but it's still a cold house with old double french doors so what we call a cold bedroom.
Easy of use: Amazingly easy to use, a small control panel with colour LED display on the unit itself or a easy to use remote control which magnetically attaches to the top of the unit. Filters are easy to insta...
Read morell/remove for cleaning although after two months have not required cleaning, I have checked. Actual use: Fast heating with even fan rotating the head unit around 180 degrees with virtually no noise. Most impressive heating it takes the chill off the room in just a couple of minutes and fully adjustable heating temperature provides economical heat settings automatically. Love the little remote, this means sitting up in bed can take the temperature up or down as required with a press of the button, easy use and quiet function of the unit itself. There is a Dyson App to use with the unit which connects easily but have found quicker and easier just using the remote or the digital display panel on the unit. This also works as a cooler in summer but have not tried this function Economy: Not seen any spike in electricity bills if anything gone down a little probably as we do not use the reverse cycle air conditioner anymore, we love this unit it performs well for our bedroom but Dyson advertisers can be used in any room, I don't doubt it one bit, our only other Dyson product is a stick vacuum Animal V7 which is awesome too, however not overly keen on the top end products as expensive versus real-world use is not fantastic value in our minds. That said this unit does replace our reverse cycle air conditioner so can see value in its purchase.

Read more Purchase cost is the reason for only four stars! Cost of filter changes RRP $999, time-limited deals seen down to $750 An easy choice Dyson provided this expensive unit to us for testing, and we certainly were not disappointed with the performance. Why Formaldehyde? Had to read up about it. Formaldehyde (carcinogenic) is given off by smoke and building materials, like flooring, furniture, woods, fabrics, glues and paints in new and old buildings and Dyson should perhaps emphasize the carcinogenic point more. Having just moved into a brand-new home we were looking for new appliances in several shops. The working Dyson fans there are a magnet with their “bladeless” fans and are starting from around $500 with the costs increasing as more features are added and with this top-of-the-range model adding a catalytic filter, which converts Formaldehyde into CO2 and water for about an extra $250. Our new house features extensive hybrid flooring and application of paints plus we moved into the inner city with lots of traffic, so this air purifier was a fortuitous addition. My wife is also concerned about pollen and dust settling visibly on our polished furniture and there has been a marked improvement. First Impressions A rather tall box arrived, and its four sides displayed a lot of interesting technical detail, which was not found in the brief documentation. Perhaps this box should be placed next to fans in shops. The box contained the unit, four loose filters, a magnetic remote and a small installation manual. Installation just requires opening the shrouds at the side and clicking in the four filters. Enter photo here of filters The manual suggested moving the unit away from draughts and in our case a large window would have caused colder and heavier air being assisted by the fan in dropping there, so the unit was moved next to a brick wall in preference. The Dyson Link app was downloaded and surprises with its many controlling functions and reports and is easier to use than this very small magnetic remote. Enter photo here of Dyson remote The unit can also be controlled via Amazon Alexa, Siri and Google Assistant, but our house has not been automated to that extent to test those features. After switching the unit on, it can be set to “Auto” mode to let the sensors look after the air quality in the room. Interesting to see the fan speed changing to changes in the environment. It is also interesting to see the air quality deteriorating on the small LCD or smart phone during cooking or when smoke is being generated, but the unit removes those smells quickly. Opening the door once to the street and exhaust fumes at the 4PM rush hour got reported as a kick in the NO2 levels on the smartphone, Enter photo here of NO2 spike, two photos were sent It being winter I was more worried about the room temperature, so I immediately set the temperature to 23 degrees and the airflow speed to a level which did not interfere with the TV’s audio signal. At Level 1 in the wind speed settings the noise being generated is barely audible, but at level 10 the noise becomes a dominant factor in the room. The compliance plate lists 2,050W as the maximum draw but at level 4 of the wind speed and heating set to 23 degrees in a room of 19 degrees the Dyson draws 2,444W as measured with an Arlec energy smart meter, With 10.6A this is getting beyond the maximum of a 10A plug. At tornado level 10 the unit drew 3,200W or well beyond what the compliance plate says and the Arlec emitted a loud pop but survived. Dyson may have to look into it. Enter photo here of 2,444W The heating provided at that level is impressive. Running it at wind speed level 4 for heating costs about $0.60/hr but is still cheaper than switching on our air conditioner at 3.300W. Using the app means I can preheat a room before I get out of bed or heat a room before arriving at home. Once the required temperature is reached, the sensor switches the ceramic heating plates off and reduces the wind speed to Level 1, which then only draws 5.8 Watts, but still purifies the air. Enter photo here of 5.8 Watts Cooling is not achieved via a noisy compressor but a Peltier unit (thermoelectric cooler), so the only noise is coming from the fan. Unlike for heating, it is not possible to dial in a desired temperature. The unit is quite a stylish bit of furniture with its golden base and white “bladeless fan” at the top and any visitors to the house will comment on it. “Bladeless” is an advertising misnomer as the airflow-generating ring is inside the pedestal making it safe from small hands and a venturi-shaped oval draws in extra air, which Dyson calls the “air multiplier technology”. Dyson models features a two-year guarantee after registration. Design and HEPA (High-Efficiency Particulate Air) H13 Purifier Explanation Two inner activated carbon filters capture gases and two outer HEPA H13 filters capture particulate matter, and two selective catalytic oxidisation filters remove Formaldehyde. HEPA is an international efficiency standard of air filters. Commenting on air purification levels needs scientific instruments, but after testing this unit for one month only and seeing less dust and the wife being happy, I am happy. As Dyson air purifiers have been tested against European HEPA standards, I must believe their advertising claims of the removal of 99.95% of particles as small as 0.1 microns, described as PM (Particle Measure) 0.1, where a micron (um or μm) is a thousandth of a millimetre and here it gets interesting: PM10 particles (100 times larger) and PM2.5 (25 times larger) than PM0.1 are already small enough to enter your lungs and throat and can make you cough, your nose run and eyes sting (Source: Victorian Health Department). HEPA filters are medical grade filters and used for contamination control in the manufacture of semiconductors, hard disk drives, food and pharmaceutical products as well as hospitals. The particulate sensor uses laser measurement to report on PM2.5 and PM10. The Wikipedia entry for HEPA lists the sizes of bacteria (0.2-2.0 um), virus (0.02-0.3 um) and submicron liquid aerosols at 0.02-0.5 micron. HEPA- compliant filters like this Dyson unit are able to capture some viruses and bacteria which are ≤0.3 μm. It is interesting to read that the size of the aerosols of Covid is between 0.05 and 0.2 μm, so it will even catch at least part of that virus; don't take my word for it, I am not a doctor! The Dyson air purifier contains four sensors, including a solid-state Formaldehyde sensor, which lasts a lifetime. The software uses an algorithm for precise air quality monitoring and reporting. The LCD and app reports air quality on a 24-hour review basis, temperature, Formaldehyde, PM 2.5 and PM 10, NO2 (Nitrogen Dioxide), and VOC levels. The HEPA + Carbon filter combination retails at $99 and the app shows in graphical form when it is time to replace, and I estimate the life to be one year. Detailed Features The Dyson Link app and the remote can be used to switch the unit on/off, set cooling or heating and desired heating temperature, airflow speed, oscillation, timer, night mode, auto mode, information and airflow direction. Oscillation starting point is set via moving the circle and the angle can be set to 45, 90, 180 and 350 degrees. Enclose photo of oscillation ex smartphone https://youtu.be/3VhkLAL0u8g Additional screens display the current room temperature, humidity, filter life and WiFi status. Continuous monitoring can be set to display environmental data when air is passing through it and to check what is making your air dirty. Timer setting means a weekly schedule can be set to turn your machine on at specific times and with your preferred settings. VOCs (Volatile Organic Compounds) are nasty chemicals found in cleaning products, old furniture, burning fuel and even perfume. A list of VOCs is listed on the side of the unit, of which Benzene is probably the best known. The display of VOCs allows you to react to changes. You may be cleaning and notice a spike in the VOCs giving you the clue to change cleaners. The level of VOCs is displayed on the LCD and on your smart phone via a colour scale, green denotes “good” between 0-3, “fair” at yellow 4-6, “poor” at orange 7-8 and “very poor” at 9+. Enter photo headed "Good" showing VOC level For our room, PM2.5, PM10 and VOC levels are in the green range, showing that the house is odour and dust free. Formaldehyde levels in this new house are in the poor range and clicking on HCHO reveals between 0.3-0.499 mg/m3 of Formaldehyde. Another display lists the given city’s temperature, humidity and VOC level and swiping it lists PM2.5, PM10 and NO2 level in parts/billion. Enter photo of showing Perth PM2.5, etc., Shows the PM2.5 level in Perth at 9 micro grams of dust per m3 of air, PM10 at 41 and NO2 levels at 30 parts/billion. You can use the fan icon to select one of ten speeds available. The temperature icon can be set from one degree Celsius to 37C and when the temperature is achieved, the fan will switch to the lowest speed automatically, so this Dyson unit can be used like a room thermostat. Auto mode will adjust the fan speed automatically and keep the air comfortable and clean. As the environment changes, the fan speed will vary during the day. A further option is focused mode and diffused mode for the air flow. Diffused mode is only available in Cool mode and blows out from the rear and means the blast of air is not directed at you. Night-time mode runs the very quiet fan at a maximum speed of four and reduces the LCD brightness. Timer mode runs a countdown timer with a choice of ½ an hour, one, two, four and eight hours. Conclusion Commenting on improvements to health after one month is difficult and I fortunately do not suffer from any respiratory ailments despite having lived next to a quarry, where PM10 levels regularly spiked up to more than 100 micro grams of dust/m3 of air, this air purifier would have been a godsend. A question to you: Are you suffering from hay fever when the pollen count goes up? Do you live next to a busy highway like I do? Do you suffer from unexplained headaches after using strong cleaning materials or suspect you are suffering from allergens? Sure, this top-of-the-range model from Dyson is rather pricey, but considering that it purifies down to a very low level of PM0.1, heats and cools and removes Formaldehyde makes it a worthwhile purchase. If the removal of Formaldehyde is not an issue, then Dyson certainly has less expensive models without this feature.

TLDR: Very nice looking machine. Heating function has been super useful. Air purifying feature seems good, but you're basically just trusting the numbers the machine shows you unless you have some kind of 3rd party air quality tester. Fan is loud on max settings, price is very high.
Appearance & Build Quality
Right off the bat, this purifier has a very sleek appearance like you'd expect from Dyson. Super classy and modern-looking appliance that I think would fit in understatedly in any living room or bedroom. The unit was easy to put together...
Read more and feels sturdy. Most of the weight is in the bottom half of the machine and it has a wide base so it can take a bit of a bump without tipping over. The only thing I found odd regarding the build is that the manual says not to pick up the machine using the loop, but there isn't really any other obvious place to pick it up apart from squatting or bending down to pick up the whole unit with two hands. Air Purification Now, I would sum up the marketing for this product as "The air around you is poison and you never knew - lucky we can sell you something to fix it", which was a bit over the top for me, but I guess that's advertising. I don't have any sort of independent air monitoring technology so I was essentially just relying on the purifier's own numbers being accurate.

I received this Dyson as part of the ambassador testing program.
One member of our household has been suffering from dust allergies for many years which is why we were very interested to give it a try.
DESIGN:
It's beautiful and you could leave it on show in the corner of any room with pride no doubt about it. People are proud of owning any dyson product and this one is a whopper and definitely the star of their fan fleet so we are happy to place it in a spot where it can be seen. The tiny magnetised remote sits firmly on top which is excel...

Overall:
Love the unit and as I have stated my only problem is that I need another one (or two). The form and function are amazing. This unit really pumps out the heat and we have offset using our split system airconditioner which is offsetting the air-con costs. For context I use this system in an open plan living household (dining, lounge room and open kitchen). This is a great addition to any smart home with the ability to control easily through an app and connects seamlessly yo my network.
The Good:
- Simple to put together - put the...

Fantastic fan/fan heater with a HEPA filter. I wouldn't really class it as an air purifier.
If I were reviewing this as a 'Dyson Fan Heater with HEPA filter' then I would be giving it 4.5 stars out of 5. It is a really great fan/fan heater but I have to review it as what it is advertised as and that is an air purifier and as such it is only okay! (It is kind of like calling the {awesome} Dyson Vacuum cleaner a Dyson Duster!!! Why?).
There are a good number of reasons to buy this including:
=====================================
- It is a fantastic/premium quality fan and fan heater.
- If you own any Apple products or any other Dyson ...

Firstly I was provided the Dyson and asked to write a review- It is not something I would have purchased as it is an expensive appliance. However, after living with it for a month I would certainly suggest people with allergies or sensitivities consider it (even if you just want less dust). If the unit was cheaper it would have got 5 stars.
The unit arrived well packed with recyclable packaging (no polystyrene). The instructions were clear and the unit assembled easily. It "clicks" together solidly and feels very well built. The app was easy t...
Read moreo load on my phone and provides a HUGE amount of information and control. It does work with google home but I had to look online to find out how (instructions mention Alexa but not google?) The unit functions very well and I left it on auto for the month I have had it. I do switch it to "night mode" when trying to sleep. The fan is not overly loud and projects air a long way easily. The heat function is capable of heating a room and the fact you can turn this on via the app before getting home is handy. It detects minute amounts of chemicals and debris in the air and the fan speeds up to clear the pollutants, and the graph on the app clearly shows what's happening and when. It really makes you aware of the pollutants we are releasing into the air. There is so much information available if you want it- or just check the basic room air quality. I thoroughly dusted and vacuumed before starting the trial and have noticed much less dust (I have a gloss black glass table top which is a huge dust magnet).

We have been using this air purifier in our kiddo's bedroom. It is easy to use and I love the Dyson app and ability to connect it to our home wifi system for remote operation from anywhere. The onboard remote it also great and it is very neat how it attaches to the top of the purifier. The app provides pretty good information re air quality and it is easy to see how the purifier has responded to times when volatile organic compound levels spike, as they do every now and then, purifying the air quickly so the spike is short-lived. There have bee...
Read moren less requests for antihistamines lately in the morning - less eye and nose irritation. I put that down to the air purifier. It has a heating and fan mode too. We have not needed to use these as we have central heating, though on one occasion when I tested the heating it was quick and effective and warmed up an average size living room quite quickly. A recommended product if you are looking at a reliable and easy to use system for air quality control in particular areas of your home.Purchased in June 2021.

We received our Dyson Purifier Hot+Cool Formaldehyde HP09 a little over a week ago.
We live in the tropics and have our ceiling fans operating 24/7 due to the high humidity.
We felt that ceiling and standard pedestal fans attract and blow a lot of dust and researched and wanted a healthier option.
We discovered the Dyson Purifier Hot+Cool Formaldehyde HP09 and decided to give it a shot.
Our main attraction to this product was the fact that the fan is bladeless making it extremely safe for our kids, it has both a hot and cold fan, and an air purifier.

Fantastic space heater. Stylish (typically Dyson). But some functions are more gimmicky that useful.
The Design:
- This model combines the previous Purifier Hot+Cool model with the new Formaldehyde detecting and eliminating function. It only comes in the White/Gold (more like bronze) colour which I think is a bit ostentatious, but the styling is what you can expect and pay for with a Dyson all the way down to the origami packaging (only a bored engineer will appreciate how much thought and design actually went into the cardboard inserts). It comes in the same size package as the previous model. The added Formaldehyde function is achieved with ...

First time use of an air purifier and have no previous machine to compare with, but have a Dyson Absolute vacuum cleaner, so well versed with Dyson quality and performance. We have an application where we have a living room with wood fire that generates the inevitable dust which we would like to remove from the air, plus a lounge room (about 25 m2) where the heat from the fire doesn't always penetrate plus wanting to circulate some air when not quite necessary to turn on the air conditioner - the bedroom can also get cool in winter and has no d...
Read moreirect heating. So far have used the purifier to circulate the air in the lounge room an also to provide some heating...the air flow has been very good and pleasantly surprised at how capable the machine is to heat the room and works best if windows and doors are closed. So far in checking the filters and the air quality graphs, indications are that the machine is doing what it claims with the air quality. There are many user settings around control, from fan speeds, to target temperature and multiple oscillation setting from 0 degrees to 360 degrees. The purifier will work very well in the bedroom (about 20 m2) and it has a night mode setting which "quietens" operation noise down plus turns down the LCD screen so no light intrusion - the LCD screen is very good and allows you to scroll through all the menus which display temperature (target vs actual) air quality levels (scales and displays from VG (green) through various levels to poor (red) - the purifier also has a formaldehyde catalytic filter as well as HEPA + Carbon filters which wrap around the internal base of the machine. The machine looks modern and attractive and is excellent design - the base is amazing, it enables the machine to be tilted back or forwards and then oscillate in that position to allow better air distribution. Its connectable to Siri, android and wi-fi enabled and supported by specific downloadable apps from Dyson - haven't used it connected to google hub yet but it is there if we need another level of control - the remote control is very functional and clever and attaches to the top of the purifier by an internal magnet in the casing so you wont lose it! Whilst its not an air conditioner (doesn't claim to be) have tried it on the cool function and it will be very good in summer when not quite hot enough to put the air conditioning on and want some air circulation...the fan speeds will run to level 10, not sure I would need to run it that high (find the balance between air and noise, though its not overly noisy) - Not exactly sure of the total power consumption but it is rated at 2050 watt - I think 1.5 kw is the rating of the heater so not difficult to calculate how much an hour to run on cooling only or heating. It is thermostatically controlled so heating turns off when reaches target temp. So far so good. Dyson quality is excellent as is our vacuum cleaner), everything is well made and fits together and functions very well! Pros: Very well built piece of equipment - typical Dyson quality ! VERY easy to assemble, set up and use Looks nice - modern, nice form and function Versatile - heating and cooling plus plus removes most contaminant's inc NOx and formaldehyde Seems to remove dust, cooking smells etc. from the air very well. Good for allergy sufferers Cooling function distributes air very well around the room - oscillates through almost 360 degreesPurchased in June 2021.

Questions & Answers
Can you run night mode on the heating setting? Can you reverse the airflow on the heating setting? I have this product and cannot do either.
Yes, you can certainly run night mode on the heating setting. The heater stays on, the LCD seems to dim a bit and the moon symbol appears on the LCD. Reversing on the heating setting seems to switch to cooling and reverses the air flow.
Hi DNR, sorry I haven't answered more quickly. domw is correct with the response already given. The night mode does allow for the heating and cooling settings to be used, changes over the airflow di...
Read morerection but if you use the higher level airflow outlet it changes from heating to cooling. If yours doesn't do this perhaps a call to customer service would be helpful. Be prepared to wait atm though they probably don't have full staff working (my call took around 20 minutes last week, 15 mins on hold but worth the wait the lady I spoke with was very good) Hope this is helpful.
While you can run the machine in night mode while heating, the display will dim but not completely turn off.
In terms of diffusing the airflow backwards, this is only available when the heater is not in use - heated air can't be diffused backwards....

Details
The Dyson Purifier Formaldehyde Range detects formaldehyde in the air 500 times smaller than particles the size of 0.1 microns. Formaldehyde is a chemical preservative that’s often found in new furniture, paint, glue, wallpaper and household cleaning products.
How does it work?
A solid-state formaldehyde sensor uses an electro-chemical cell to detect formaldehyde in the air. The special formaldehyde filter - the Selective Catalytic Oxidisation filter - then works to destroy formaldehyde, turning it into harmless water and carbon dioxide.
The formaldehyde filter is a lifetime filter, so it won’t need to be replaced for the life of the machine.
Features
- Dyson's latest air purifier has the ability to heat, cool and purify a room.
- A HEPA H13 standard filter captures 99.95% of particles as small as 0.1 microns, including allergens, bacteria, pollen and mould spores.
- Designed with standard features of previous Dyson purifier models, including Auto mode for the heating function, Air Multiple technology for wide air circulation, Night time, Sleep time mode, and the ability to be operated using either a remote control or the Dyson Link App.
- Voice control using Google Home, Alexa or Siri is also available with a compatible smart device.
Points of praise
- This 3-in-1 fan, heater and air purifier provided fast and effective air circulation. Multiple reviewers happily reported that it was powerful enough to be used in place of a reliable split system AC and even a ducted AC system in a small zone.
- This Dyson model made a room nice and toasty warm within minutes. It worked well even in rooms that were naturally chilly or had poor insulation.
- Ease of use was generally reported to be good, with the app being easy to navigate. It was also considered easy to change filters.
- The air purifying function was appreciated by reviewers who had household members with allergies and other respiratory issues. They observed a noticeable improvement in breathability in a room after the Dyson was used.
- The unit is highly portable and easy to carry between different rooms in the house.
Points to consider
- The expensive purchase price of the unit ($999) was noted by reviewers, and it often docked at least a star from individual ratings. While it was acknowledged that this fan heater and purifier performs 3 functions, the asking price was still considered to be out of many people’s budgets.
- It was also noted that purchasing new filters represents an additional ongoing cost.
- A number of reviewers reported that the fan heater could be too loud, especially if used on a high setting.
- Not many people really knew if the formaldehyde-capturing function was working, but commented that it sounds like it can only be a positive addition to the machine, after researching the benefits.
