Customer Ratings & Reviews

My room is around 900sq, so was sketical. It heats the whole room and helps with air purification. People state it’s impossible to connect online. You have to connect with your 2.3gb not 5g broadband. Most routers have both, just look under your router. I had the same problem with my roomba so gladly knew I connect my phone to my 2.3G and forget about it. Once connected you can control with your original WiFi, if you use 5G. Or no WiFi. Can control from work.

Dyson consistently delivers quality products that perform better than promised.

My allergies are bad and the allergy season only gets worse so I got the Dyson as a little something to help me breath better - nice clean air. And I am not disappointed. Quiet enough to sleep and the heppa filter gives me a breath of fresh air at least at night. So while this is a very expensive item thus far it works and I like it.

I’ve had this purifier for a about a month now. I love noticed a difference. I have bad allergies and this is helping out a lot. Heater feature is coming in hand on these cold evening. I don’t know how much of a cooler it is. I would say it’s more comparable to a fan than cooler. Otherwise great product.

Works great refreshed the air in my room in a few hours I sleep better at night

I do like it, but not as quite as I would have expected. Also, the fan portion really doesn't cool. Heater is good though.

Good product for heating and/or cooling a small space while cleaning the air.

Purchased this for my young kids' room. Both have suffered from breathing problems/asthma and we use a space heater in their room on chilly nights and a fan on hot ones (living in SF, air conditioning is not necessary or available in our 1920's flat) This product was an all in one for us, eliminating the need for multiple products plus offered the air purifying feature. The app is simple to use, love that it can be controlled remotely, even when we are not home. We leave it on auto most of the time and so far, so good. My daughter used to wake up coughing a lot at night and that has stopped since we purchased this product a few weeks ago. I want another one for my room too!

Great product bought for my friend who has issues being near the ocean and this definitely solved the problem with the dust.

This Dyson hot n cool link 400 air purifier is amazing. I’ve purchased three other air purifiers over the years and this one is better than all three of them put together. My son has allergies and asthma and is living in a basement room that is musty and even perhaps moldy. This Dyson air purifier not only helped his allergies but cleared up the musty smell completely. It also heats and cools his large room quite well, without a huge rise in the electric bill. I was able to get a prescription from his doctor for the air purifier and use my flexible spending uncovered medical expenses to get reimbursed for it. Well worth the money!

Such a great all in one fan, and easy to set up. All you have to do is download the app, and it walks you through the whole thing. I love how it tells you the air quality in the room. And the temperature sensor is spot on.

I recommend this product for your home. I like the cool and hot option but bought it for the air purifier needs.

This product is very good on heat I don’t regret I bought it. I will recommend it to my friends and family thank you.

This product is worth the month. Has multiple functions and can be controlled by the Dyson app. I swear by this brand as i also have a vacuum. This keep me cool in the summer and warm during the winter.

This Dyson unit was simple to use and highly effective in providing a safe heating source. Dyson products from personal experience are high quality and durable. We have yet to use the cooling option for a prolonged period.

The best of the best for all rooms stinking pet orders and refresh air

Sturdy, well made, and works perfectly. Expensive, but truly worth it.

This is our second Dyson Air Purifier but this one also heats. Perfect for our breakfast room which is full of large windows and can be chilly. This is place were we spend a lot of time...clean air AND warmth, perfect !

Bought this because of the name to assist with asthma and dogs in the home. Works wonderfully. Control through your phone and the ability to heat or cool is great. Great product!

I bought this mainly to use as a fan, but it helps to use as an air purifier as well, and the heater is a nice additional accessory although I haven't needed it and probably won't use the heater much. I am using the fan in my bedroom, where it is very quiet and works great to circulate cool air very nicely. and I hardly even notice the air movement. The speed range is a great plus, if I need more air movement, but I found the proper setting where it is most comfortable for me. My dog loves to lay in front of it and enjoy the cool breeze, and he would not tolerate any other normal fan. It's a little pricey but I have had good experiences with other Dyson products and I feel it is worth the price for a quality product, and it's perfect for my needs.
