Web ID: 19709611I am grateful for this technology!
I love the formaldehyde feature on this Dyson. I like that it shares date on humidity so can know whether or not I should purchase an air dehumidifier.

Temperature + Sensor FAULTY
Terrible design and faulty placement of sensors. The way this item was designed is that the sensors were designed and placed within the machine too close to something that produces heat so the temperature sensor is always reading 5 degrees higher than the room! Whoever designed this must be a complete newbie at it because that’s not how this should have been designed. Without fail, 5 degrees higher than other dyson machines (trust me, I own 5 other dyson purifiers) and even compared to the Google Nest thermostat, it ALWAYS reads 5 degrees higher. Faulty design and terrible quality control.

The best air purifier money can buy!!
So far, I’m very happy with this air purifier. It has exceeded my expectations. It’s super quiet and I no longer see any dust flying in the air. I have a huge allergy to dust and this is so helpful. Also, with all the Canadian wild fires. It’s especially helpful in keeping our household air clean and fresh. This is worth every penny!!

Great for allergies!
I am so happy with my purchase. The Dyson Purifier BIG & Quiet is an accurate representation. It's helped with my husband’s dog allergies. We have a hyperallergenic puppy but even with a hypoallergenic dog, he couldn't spend too much time on the first floor without having a mild reaction to our puppy, since having this purifier the allergies have subsided. I also love the design, it aesthetically pleasing and didn't clash with my furniture. Highly recommend this product, so worth every penny!

Great looking purifier
A machine that reports what it is doing which I have confidence in. Even when I apply a cologne in another room it is not long before I hear the fan speed increase and the Purifier reports something in the air, removes it and returns to its normal operating state afterwards. Even kitchen smells are removed quickly and efficiently.

Crackling sound within two weeks of usage
The air purifier works but within 2 weeks of usage, a sound started, like the rope of a hammock. It goes away for a couple of days when turn it off for a couple of minutes, but the crackling sound comes back after a couple of days.
