no reason not to buy it if you have dust/any allergies

SuperdipJune 4, 2025

i love this so much, worth the splurge for allergies. Auto mode is awesome, it’s pretty quiet too unless it’s filtering something out super hard but nonetheless the background noise is unnoticeable. Basement smells good and the formaldehyde option is honestly just for peace of mind down there because of moisture. it’s super cooling and i’ll probably purchase a non-formaldehyde version upstairs in my house knowing how much i like this one now. Dyson is honestly so easy to set up and use, i don’t know why i waited so long to get one. The monitoring system works in real time in sync with auto so you have to do nothing but keep it plugged in and you’ll have clean air for good. stop being lazy and unhealthy and just buy it if you’re on the verge Read more

Fresh and clean air

Tamara GarciaFebruary 1, 2025

This looks good, feels good and smells good. You can feel the fresh and clean air when using this fan. Dyson does not disappoint, is a healthy environment combined with a beautiful fan for the room. We will be adding more of this to the home. It has multi speed functioning, rotates, you can set for a specific amount of time and is very easy to assemble and clean. We leave this on all day for it to continuously clean the air in the room, then adjust to higher settings at nighttime. You can also use it silent or make some more noise if white noise is needed (we do). Great buy for us. Read more

Stopped working properly after 3 months

Was a SellerMarch 14, 2024

This machine worked great but around the 3 month mark the air quality reading changed to a constant green flat line and the other readings do not register. In addition, the motor makes a loud whirling sound and I can't get the fan to turn off unless I power off the machine which negates the purpose of having a machine that reads the air quality. I tried all the troubleshooting I could find on the Dyson website, community pages, Reddit, etc. but nothing worked.. I then contacted Dyson directly and was given canned responses that were the same as I read on the Dyson website and on their troubleshooting community pages. No help whatsoever. So disappointed. Won't buy a Dyson product again when there are so many other options out there now. Not what I expected from Dyson or a $600 Dyson product. Read more

Best fan/air purifier on the market

DC SmallJune 21, 2025

Great product! I have two Dyson fans I have this model and I have the TPO7 Both of them are great fans and you can really tell a difference. I had to send my TPO7 off after having it for three 3years to replace a bad sensor and I could truly tell the difference with just swapping it out with a regular tower fan for in bedroom. These fans are expensive, but they’re worth it.. I only have one complaint. It’s kind of noisy my TPO7 wasn’t this loud. Read more

Works for HCHO formaldehyde

SherbertlaneSeptember 30, 2024

Cheapest option I could find to clean formaldehyde from the air in my house, and it works. I work from home and was having constant “allergy” symptoms for almost a month straight, but only in my house, after buying an air quality tester it turns out we had high levels of “HCHO” or formaldehyde in the air. It wasn’t that much higher than outside and we live in a hot climate, so “airing out the house” wasn’t really an option. Bought this and immediately plugged it in, within a day my “allergy” symptoms were gone. A week later, and the air quality is down to safe living levels. A win for me and my family! It’s not that loud compared to most fans, so I’m just going to keep this running. Now I just need to figure out how to keep my toddler from playing with it… I wish the swivel had a child lock feature, but that’s the only downside. Read more

11 month review

RGBCMYKEROctober 2, 2025

It can get loud at higher speeds but it’s mostly quiet up to level 6 of 10. I have this unit and the smaller one and they work really well. It’s remarkable how much they catch even when being conscientious about swapping home HVAC filters. I’ve had the most comfortable allergy season at home with these units. Read more

Great deal! Quiet, cool and slim

RegineJuly 3, 2025

Tbh… I really wanted the hot plus cool with the purifier but for the price I got this, I had to cop. It’s easy to set up and does keep my office area cool. Idk if I’ve noticed a change in air quality but my fan is also my patio door that I open regularly. Overall, I appreciate this doesn’t take too much space, it’s very quiet in comparison to other fans and does what it says it’s supposed to Read more
