    This is quiet, easy to set up and programming is easy and straightforward. Set it on auto and it purifies and heats or cools to a temp you set.

    Dyson air purifiers are the best they monitor the air quality 24/7 and notify you if there is anything detrimental to your health going on!

    Best fan ive eve owned, heats well. My air has never been cleaner, what a fantastic product. The only downside is the heater turns off after 8 hours if use automatically, and you cannot use the mobile app to adjust heat or turn on.

    I purchased this unit because the air quality due to the wildfires in Northern California was so bad. We have been running this unit on automatic for 10 straight days. It automatically changes the speed of the fan as needed. Air quality was over 400 outside when we first started, but our Dyson kept the air quality inside our cabin at 20 or lower. I’ve tried the oscillating mode once, but mainly just ran it on a fixed directionsince we didn’t need the oscillating option as much as we just needed clean air. Tried the heated air mode just to see how it worked, but in 85 degree weather we certainly don’t need that now. I’ve mostly controlled the unit on my phone or iPad, but the remote works just as well. It’s just that my iPad and phone have been much closer to me. I like the graph of air quality as well as the specific read outs of PM 2.5, PM 10 VOCs, Nitrous Oxides and Formaldehyde. I’m not aware of how long the filter will last, but they seem a little spendy.

    The product is decent-ish, as long as you know what you're getting into and why you need or want this product. It's a decent all-around product that doesn't excel in any one key area. It's more of a personal fan/heater/purifier, a product that should be kept close by the user. Not the best fan in the market, not the best heater, and definitely not the best purifier by far, but a nice combination and ease of use with a great feature set. There are other issues though, such as manufacturer issues, the build quality history of the Dyson purifier product line, and their dodginess with advertisement claims and related questions. (I would lean towards purchasing a warranty service protection for such a high cost, if one is determined to buy this and not an alternative) Another key issue is the price-to-feature ratio, it is way off and the corporation is asking way too much for what you will get. But as of right now there are sadly no great alternatives that have the same all-in-one package.

    This product works great! Purchased for my nursery. It gives me piece of mind for my newborn knowing the air quality is good and when there are any issues with the air quality, this unit takes care of the issue fast. The cooling and heating features also work great.

    Cleans the air and tracks particle rates over time. Lots of settings through the app like night mode and timed shutdown. Heats and cools which is a plus for many purifiers. Not as much air flow as compared to a fan, but still blows and heats.

    We got this about 5 weeks ago and it is the best thing we have ever purchased no lie. My one cat has asthma and I'm not kidding since we've had this she has not had 1 asthma attack and our air has never been cleaner in our townhouse. It has truly been life changing I have recommended this to my nephew's who have asthma my brother who has asthma I truly highly highly recommend this. I just leave it on the auto mode and whenever it detects anything at all in the air it immediately turns on and starts cleaning the air it is amazing.

    Love this thing! Worth every penny. This replaced a space heater and filter for us. Nice to have an all n one that I can check on via WiFi to make sure the pets are doing ok in the heat/cold. It is a bummer u can’t turn in the heat via wifi something to do with safety.

    Works great! I haven’t done any scientific testing but from what I can tell the air does seem cleaner and it’s pretty quiet on lower settings! It’s feature packed and since the weather is cooling down it does heat up the room well!
