All In One
I bought this a month ago and I am happy that I did because the airflow was very good the heating was very warm. The important part is the filtration because I sneeze often, that is what I bought it for.

Filter replacement
I bought a replacement filter and it’s great - works well. We had a crazy spraying neighbour which is why I bought the purifier, it works quickly when the aerosol is in the air and it quickly dissolves it. Very happy with this product. In winter it’s great to have the heat option. I feel blessed to own this product Thanku
From Dyson Customer Care team
Thank you for your review. We're thrilled to hear your replacement filter is performing so well and that your purifier helps provide quick relief when airborne aerosols are present. It's wonderful to know you're enjoying both the purification and heating features, and we're grateful to be part of such a positive experience in your home.

Great Features, But Disappointing Fan Power
I bought the Dyson Air Purifier HP2 De-Nox because I wanted an all-in-one unit for heating, cooling and air purification, including helping remove unwanted pollutants and toxins from the air. The main disappointment for me is the fan power. Even when the fan is set to speed 10 (maximum), the airflow is nowhere near as powerful as I expected. I bought this unit partly for the cooling function, but the weak airflow makes it less effective when I want to feel a strong breeze or circulate air around the room. The heating and purification functions are useful, and I like having everything in one unit. However, considering the price, I expected much stronger airflow at the highest fan setting. Overall, I would rate it 3 out of 5 stars. The features are good, but the fan speed and airflow are a major weakness for me.
From Dyson Customer Care team
Thank you for your review. We're pleased to hear you're enjoying the heating and air purification features. We appreciate your feedback regarding the airflow performance, and will pass this on.

Fan strength on "cool" is a bit disappointing.
Only bought this until about 3 weeks ago. So far it's ok, but I must admit the fan power seems a bit undercooked for a unit of this size.
From Dyson Customer Care team
Thank you for taking the time to share your feedback. We appreciate your comments about the fan strength on the "cool" setting. It's great to hear that your machine has been performing okay overall after the first 3 weeks of use, though we understand that the fan power has felt a bit underwhelming for a unit of this size.

works well
Air flow is good. Filtration of orders very good. Cooling is helpful, room to big. Heat index 105, have not tried heat!!!! Quiet
From Dyson Customer Care team
Thank you so much for taking the time to share your feedback! We are thrilled to hear that you are enjoying the impressive airflow, quiet operation, and excellent odor filtration of your new machine. While it may have a challenge completely cooling a very large space during an intense 105-degree heat index, we are glad the cooling feature is providing some helpful relief. We hope the heating function keeps you cozy and comfortable once the colder weather arrives, and we look forward to keeping your indoor air clean and fresh for a long time to come!

Constant low noise while running
I bought this about two weeks ago, and it has mostly been running well. However, it has been making a strange noise while running from the beginning. I’m planning to return it when it’s convenient for me.

Good purifer
Bought this for a city apartment. Love the look and functionality. Heats quickly when using that option. It's a little louder than I was expecting on sleep mode but it becomes background sound pretty quickly.

Could be perfect
After heating is turn off, you will hear panel cracking sound. Would be good to be able to add this into HomeKit.

Disappointing
It’s not as powerful and doesn’t generate enough heat. I have it operating at highest temperature and maximum fan speed. In fact I can feel a cool draft from the fan.
