I had a newer gen of the Dyson hot + cool link that I LOVED. Had it for years running constantly. A power surge broke it. I bought a cheaper air purifier but it wasn’t the same. I like something blowing on me while I sleep but I need CLEAN air. A normal fan blowing on me gives me terrible allergies. That’s why I fell in love with the Dyson air purifiers that blow clean air out the front of the machine as powerfully as a fan if needed. I only used the heater function rarely (like the day the furnace went out we were very happy to have the option). It worked very well I just don’t like space heaters on a regular basis. This machine does all the important things for cheaper. It doesn’t connect to the app, the remote is the ONLY way to use it. This was stated in the description and I was ok with it for the price. I paid $345 for a refurbished “very good” condition HP10. The product came looking brand new. However, the remote was missing, making it useless. I tried to contact customer support to try to get help from the seller directly. Customer service experience was terrible. I knew I would have to purchase the remote through Dyson directly but I wanted refunded for the price of the remote. Couldn’t get any help from Amazon or the seller, they just kept offering for me to return the product. I didn’t want to return it, just wanted the remote for free as advertised. The exact remote wasn’t available on Dyson’s website. Dyson made it right though. I called Dyson’s customer service and they sent me a replacement remote for free. Minimal hassle. Overall annoying but worth the price difference (I paid $600 for the new model). It’s pretty quiet. Turned up to 10/10 you can definitely hear the air coming out of it, but I like that. Just enough white noise without being too loud. Turned all the way up it puts out quite a bit of air for the size. I sleep so much better with it. If you leave the display on (I usually keep it on night mode so the screen doesn’t create light and then I turn the fan up a little bit once the screen is off) you can tell it definitely works. If I spray hairspray in another room nearby the air quality percentage drops dramatically but goes back to almost 100% clean air after about 2 minutes Read more
