Dyson Purifier Cool TP4B Purifying Fan

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.

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.

It is a bit noisier than I thought it would be, but the flow of air is very nice. It doesn't blow stuff over. Haven't checked the filter yet, but we have it sitting up on a low table, so I imagine it is still pretty clear.

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.

A good, quiet fan. Easy to sleep with it on. But that price. Have to almost take a second mortgage.

I'm a Dyson fan. Besides that, this is a very well connected wifi device, has a great mobile app, very informative monitor, and very customizable controls, schedule and everything. Actually bought another one for the bedroom too. Expensive, very expensive too.

I ordered an open box refurbished machine which comes with guarantee and is supposed to come with authentic parts. In this case the remote was not working nor was it authentic (not fully magnetic due to the plastic buttons which the original remote doesn’t have). I have been in touch with Dyson to get an original remote but the item was out of stock for 4 weeks. As it took quite long and I missed my return window with Amazon Dyson offered me to send back the machine and send a new machine instead. I appreciate the solution. Machine is great, beautiful and the Dyson quality you expect. I like the app where you can track air quality and temperature per room where you have a machine installed.

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!
