Reliable features
Wow, purchased about a month ago and exceptionally pleased with the overall performance of the air purifier. Excellent airflow which covers the whole room either oscillating or still. Fantastic low noise for night sleeping, we don't know its in the room. Automatic sensors are brilliant. Recommend this air purifier

Upgrade
This was brought for me as a gift because my old Dyson tower fan had become noisy. I do like this new fan it is a lot quieter and like that I can connect to the Dyson app I would say the airflow could be cooler

Excellent purifier
As a HEPA Purifying Fan it is excellent. I have read some negative comments about it as a cooling fan, but that is not it’s primary function.

Stylish
Expensive, but well-made. It does exactly what it was designed to do, to maximise airflow and on the lowest levels is quiet enough for the bedroom. I take one star off because the Dyson Alexa skill (aparently produced by Dyson themselves) is faulty - it's partially in Japanese. And a second star is taken off because the issue with the app was reported months ago and no one has done a thing about it.

Its good but not quiet
The fan is not as quiet as advertised, on level 10 it blows out a lot but you cant sleep however on level 5 its quiet but not strong enough to make any difference.

Quiet but not as powerful as older model
Not as noisy as the other one we have, however this appears to have affected the power. It doesn’t blow as hard in an effort to make it less noisy. Sensor can be somewhat awkward to reach as it doesn’t quite catch the signal from the remote when it isn’t directly pointed at it. The coverage is good - as long as it’s turned up fairly high where compared to the other purifying fan we have. Filtration seems fine.

Well designed
I am really happy with the air purifier. It shows me when the air in the house is not so good. it surprises me that air quality is poor especially when I cook! It is very quiet which means I can leave it on for longer periods. The night mode is also excellent and causes no disturbance at all.

Not really a fan but a good purifier
I purchased this as it had good reviews! The air flow on this is pretty poor, I’d probably get better from a cheap fan. This is definitely more of an air purifier rather than a fan. I wouldn’t recommend this to keep you cool
1 reply from Dyson team - 3 months ago
Thanks for your review. We're glad to hear you find the purifier effective. The TP09 is designed primarily for air purification, with airflow intended to support whole-room circulation rather than direct cooling. We appreciate your feedback and are always working to improve. If you need help choosing a product better suited for cooling, our team would be happy to assist.

Dyson HEPA Purifier Cool TP09 Formaldehyde
The airflow seems to be better than most fans and it does cool the room down. It does get noisy when run at higher speeds but mid range is reasonably bearable. The coverage of the flow has been kept at 90 degrees and that's quite adequate.

Great Machine.
Our son bought this for us as I (his Mum) has lung problems and it is absolutely marvellous. It is also so quiet you do not know it is on. It was the perfect present.

Misleading marketing
I’m quite confused by this product and the marketing around it. Should they be allowed to market it as “cool” air? Bought it during a heatwave to help cool down and clean the air especially of cooking smells. The fan element is shockingly weak and certainly not cool air at all. A tower fan I bought from a supermarket for under 30 pounds offers more of a breeze. I also didn’t feel that the fan did much to get rid of cooking smells or smoke from our downstairs neighbour coming into our flat which was one of the primary reasons I wanted it (aside from the promise of “cool” air). We returned this and bought an air conditioning unit instead for the same price. Much better.

Thank you for your feedback. The TP09 is designed to purify the air while providing a stream of airflow for personal cooling, though it does not reduce room temperature like an air conditioner. We’ve shared your feedback with our product team and appreciate you taking the time to share your experience.

Not worth it
This purifier is ok - I question the reliability of the sensors because almost every time I turn the purifier on, the air quality worsens which I find very strange. Not worth the cost, disappointing. The fan is also pretty terrible.

Not very good
Bought this a few weeks ago now and find that it doesn’t blow very cold air out at all, even on the highest setting. If I hadn’t have thrown the box away on the day of purchase I would have sent it back!
