Purifier Hot+Cool Formaldehyde™ HP09

This was pricey but I’m glad I purchased it. It works great and is very quiet. It cools and heats our sunroom well.

Absolutely love this. I love how cool it helps keep our upstairs in the summer and it gives my daughter some heat in the winter. I also love how it helps purify the air. It's extremely quiet unless it's on the highest setting, but I don't mind the white noise.

Absolutely amazing. These fans are quiet, and have the best air filtrating that we’ve ever had (2 dogs and 3 kids)! We have them in most rooms now because they work so well. My wife and daughters love the heat option in the winter too. The price is certainly limiting, but we wait for them to go on sale. Scheduling on the app is super easy to use too !

Does not work well. Stopped working after the return window ends. It doesn’t connect with the phone it keeps reading “offline” the worst part is it just doesn’t even purify the air. We had work done in our house and they worked with very strong chemicals. I have air quality sensors in every room of my house and all of them were reading the highest level of toxicity. The Dyson kept reading perfect air quality with 0 contaminants. It’s a fraud. Opening the window cleared the air faster this junk. Does not read the air and does not purify it. Oh also does not “cool” it just blows air like any old fan.

I bought this during the summer because it says that it’s supposed to cool. It does not cool. It’s easy to use, but it’s large and noisy. It’s not worth the money I paid for it. I kept it because I had a problem with another brand and had to mitigate some damage done to my home by the other brand. It does get rid of all odors, and I am hoping that it will improve my air quality. I really like that it shows you the amount in your air of several different pollutants that could be in your air. It didn’t say that there was anything wrong with the air for several weeks, but it did detect a tiny bit of CO when it was placed near the gas stove on a day when we were doing a lot of cooking, so I assume that all of the detector functions are working properly. The heater function works nicely for keeping my dog warm. It seems like too much money for what it does. The remote has to be placed face down to stick to the device. It would be more useful if you could use the remote without having to pick it up each time.

Works perfectly the only downside might just be wind speed I wish it was stronger you have to almost be in front of it to feel it. Otherwise it does clean the air in my room rather quickly and allows me to monitor contamination in the air.

Has been working great so far both in terms of heating and air quality monitoring and purification.

I'm just waiting for this product from Amazon Prime Day. I ended up purchasing two, and so far, so good—I love them!

I am happy with this product from Amazon

Second hand product? I just received the product, it looks ok at the moment but the filter show that is like not brand new. I wait for the seller to see what’s next and I consider to return it and to buy from Rona, Home Depot or Best Buy. At least you could talk with someone about it.

I was not satisfied with the product so I requested to return the product but they want me to pay for the shipping to return it and take some percentage of my payment for return. I find that fraudulent! Do not order from 3rd party!

No warranty buying through Amazon as the dealer was unauthorized by Dyson
