Expensive but worth it!
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.This thing runs great and with the app you can set a timer for it or schedule. Runs heat and cool. Auto mode takes some getting use to but a 5/5 product.

Substantial Air Quality Improvement
||Posted . Owned for 1 week when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.The best investment in air quality I have ever made. I can rest easier knowing the air is constantly being purified and monitored.
I would recommend this to a friend Great hot and cold fan
||Posted . Owned for 1 week when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I recently bought this hot and cold fan because it had the air purifier option. Just remember that the filter needs to be changed to be efficient. With the cost of the fan and filter it is quite expensive. I suggest buying this with a coupon or best buy rewards to cut down the cost. Overall, it has great wifi feature to control the fan while you are at work. The app works well and have not had any issue.

||Posted . Owned for 6 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.I purchased this machine in May 2025 very excited because i had seen great things about it. Day 1 out of the box the remote quit working. I contacted dyson and they took forever to reply 8-9 minutes each message sent in chat then said it was on back order and that theyd send an email when avalible. Well months passed and i heard nothing so i reached back out in September and they said they still didnt have them and told me to go to the nearest Dyson Service Center that is 6 hours from me. Mind you, the new models have rolled out and they take the EXACT SAME REMOTE. How do they have the remotes to roll out new ones but not for customers that already paid $900 for the purifer. Probably wont buy anything else from Dyson.

Great Purchase

Best space heater
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Looks good and works good. Even though we have a very good central heating system, this space heater is extra heat, focusing where it is needed.

Solid build, smart control, pricey but worth it
||Posted . Owned for 2 months when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Easy to set up and control. Being able to display different metrics (e.g. air quality) is very informative. The build is solid. A little pricey but you get what you paid for.

Don’t do it..
||Posted . Owned for 3 weeks when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Very expensive fan. I purchased it thinking it had cooling properties. It doesn’t, it has a heater built in and purifies as well but many other products do the exact same thing and cost $100-$200. Not $1000.00

It works and it delivers
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.It's expensive but man, does it work and deliver on its promises. One day I spilled my bourbon on the desk and this thing went into overdrive at the other side of the room giving an alert on sudden increase in VOC levels. I love it - it's expensive, but I think it's worth it. It's really smart and diligent on temperature levels as well. So I think it's going to break even soon - compared to my Honeywell space heater which has a different understanding of thermo-dynamics and lives in a parallel universe where Fahrenheit is calculated differently.
I would recommend this to a friendLove this thing so much!
||Posted . Owned for 1 month when reviewed.This reviewer received promo considerations or sweepstakes entry for writing a review.Cool and convenient with sophistication! Find what contaminants are bothering you if you have allergies to pollens or mold and figure out where you can put it in your house for maximum efficiency and effectiveness! You can even switch WiFi networks seamlessly. Brought it to a shore house we rented and it worked awesome with keeping the air nice in a humid and moldy house
