    The Dyson air purifier is a great addition to our home. Cleaner air, added humidity in the winter makes a big difference. The wifi feature is great, can view and change settings any where on Earth.

    Great for the bedroom. I use this over night to keep the air in the room better because before it would get really dry and I would wake up with my sinuses all crazy. The water level has lasted me a while even though it says 36 hours of use it’s been over a week at least.

    It is expensive, but I have slept a lot better since buying this. I keep it at the max humidity and it provides the right level of low back noise. Looks nice too! Glad I made the investment. I would recommend the insurance though as it's a $1k fan.

    Works great, wonder what I would have done without it. Cleans and humidifies while cooling. Would recommend to someone that has breathing issues or allergies or just enjoys clean air.

    This thing is awesome. At first I had buyers remorse because of the price. A week later was already thinking about buying another one. the humidity and room temp stays constant while at the same time filters the air. This thing is powerful. Haven’t slept this well in ages. I own a lot of instruments , equipment and records. It’s nice to know that the humidity and temperature will stay constant. Only thing is you need to remember to clean the water tank and always keep it running so no mold or nasty stuff accumulates in there from sitting stale.

    This rocks, it cleans the air 24/7. Whenever perfume or some contaminant is in the air, it goes straight to work until air is clean again.

    Works as advertised. Had purchased to help with allergens and congestion. Improvement in our home was felt with the increase in humidity and filtration. We keep in our bedroom. When its on, it is not too loud and also cools the room at night. I also enjoy the app too and not having to rely only on the remote. Maybe could have the same results from a less expensive unit but i know the Dyson brand is reliable and with the TotalTech coverage it gave me peace of mind if I encountered any issues that it would be taken care of.

    I never imagined I'd buy a pricey air purifier but I just moved to an area where there is a lot of construction and therefore a lot of dust. This purifier does an excellent job of keeping my allergies at bay and my extremely sensitive eyes comfortable.

    As others have stated, this thing even on max settings cannot get a room above 40-45% humidity. I spent $1000 on this, and have pretty much never regretted a purchase more. The room it's 400sq ft so for the price, it should be much better. I'm going to try my luck at customer support after giving the device every possible chance to get better. If I don't get anywhere with them I'm going to try and sell it on Craiglist. It's pretty much doing nothing but taking up space at this point. Posting here to deter others from making the mistake I made in spending so much money on a useless device. The only redeeming qualities seem to be the device's construction and ease of use.

    No, I would not recommend this to a friend
