DysonPurifier Hot+Cool Formaldehyde™ HP09

First, I've owned this for almost a year. And when I mean almost a year, I mean in three more weeks, it will have been a year. I have to say, in regards to this purchase, this device exceeded my expectations. Not only did it exceed my expectations, but a lot of the complaints I have heard, I don't see here. Or I don't hear, for example, the loud noise. This fan is just wonderful.And keep in mind, I am just getting ready to replace the filter now. It's at 4%. So, this filter claims it should last about a year. And keep in mind, I have been putting this fan through heavy use throughout the year. I have it scheduled throughout the day to go into auto mode or to start blowing during certain times.During the winter, usually any time between 8 to 9, I will have this fan having heat come out until midnight when I have an auto shutoff scheduled. So, yeah, this, believe it or not, has replaced our space heater. It just works so well. And I'm shocked at how well this specific device has worked.In fact, most likely near the end of this year, I'm going to have to buy another Dyson. Not this model, but basically another model that's smaller that could fit somewhere else within my apartment.Again, in terms of the noise level, it's no different from any other fan. I want to say, unless you have something wrong on the inside, this fan is perfectly quiet. This fan does pick up a lot of dust. It's very easy to clean. And again, it just operates wonderfully.Now, I have this fan at the edge of my apartment where my Wi-Fi could reach. And again, it still works wonderfully. If I accidentally leave the heat on and I know I need to turn it off, I could just get on my Dyson app and just completely turn it off.It integrates well with Alexa. Unfortunately, it does not integrate well at all with Siri. And I think it has to do with the United States regulations that you cannot use the smart app to actually schedule heat to turn on. Unfortunately, in the United States, that is now against the law.So if you're not a big fan of that, please call your congressman or your senator's office. Because again, the fact that you could just schedule things is great. Not only that, but it makes it safer. Also, it makes it safe that you could actually turn off your fan at a certain time so you just don't leave it running.Again, this is a wonderful buy. If you're in an apartment, you will appreciate it. Again, it's pricey. Keep that in mind. But it's one of those things everyone in my household just loves. At first, there were complaints because of the price. But again, it's something that has grown on each and every member of my house.So please consider this purchase. It does exactly what you want. And the things it does not do, honestly, you could blame that on your congressman.

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 !

Although I purchased this on sale, I am delighted to have spent so much money on this item. Living in a rural community, when the power goes out for two days in the dead of winter with negative temperatures, is a scary thought. However, the heater on this unit kept my living room, warm enough for me to hesitate and make it through the storm. I have used it every day and have not needed to change the filter yet.

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.

The only reason why we bought this WiFi version was to be able to control the temperature via WiFi... seems like a basic thing to be abe to do with a connected fan, right? WRONG. Due to some silly US regulation, any US-made versions of this have the temperature control remotely disabled, and there's no way to enable it, so the main useful feature of this unit is rendered useless.

This has been a lifesaver in our daughters room. Super easy to use, and heats her room nicely on extra cold nights when our HVAC doesn't keep up.

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.

Lots to like, effective, works as advertised, nice looking in my bedroom and has a cooling feature that’s nice. It’s not cheap but is high quality.
