    • no reason not to buy it if you have dust/any allergies
Style: TP09
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 ... show more

    • Fresh and clean air
Style: TP4B
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. ... show more

    • Doesn’t smell right
Style: TP09
Review Image by Ghost Ghost
I own few dyson air treatment product. And this TP09 does not smell right. Something is off. It smells a combination of metal, plastic and kind of like those carbon activated bags you buy to get rid of odors. Except those are much pleasant in smell and make everything fresh. This dyson blowing in my face a scent that is not ok. Almost worried about inhaling it. I hope dyson didn’t go cheap on their filters and now even on my other once when I need a new filter they’ll smell the same. That will be the end of dyson. I did read online that their filters don’t smell the same anymore. I will return it today. ... show more

    • Best Amazon Prime Day Purchase Ever
Style: TP09
I've been eye-ing this product for awhile and I'm SO glad I purchased it during Amazon Prime Day Sale. Biggest concern I had was the high-pitched noise that everyone was complaining about. I had a $40 fan in my room before this and honestly, Dyson's "high pitched noise" is nothing compared to the cheap fan noise I had before. Filter is SO easy to put in, mobile app is so nice to have, and the little display on the fan itself showing different levels of particles, NO2, HCHO, etc is really nice too! I honestly didn't think I'd need Formaldehyde filtering but to my surprise, my room had high levels of it! I HIGHLY recommend this to anyone who has limited space and can't have both a fan and an air purifier in the room without losing floor space. Personally, fan function works good enough to cool me down at night. ... show more

    • Best fan/air purifier on the market
Style: TP09
Review Image by DC Small DC Small
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. ... show more

    • Very cool air filter!
Style: TP4B
Love the design! I have this in my bedroom and I have slept better since I bought it! It does circulate cooler air and it has a nice white noise. The remote control works well. It seems to sense air irritants like candle smoke. Other than that I am unsure of its air purifier capabilities. But I really love the design and anything that helps with a good nights sleep is priceless! ... show more

    • Great deal! Quiet, cool and slim
Style: TP4B
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 ... show more
