Description

With the Dyson Purifier Humidify+Cool Formaldehyde - PH04, you can do more than clean the air. The device spreads cold air and humidifies it too. The air purifier has an air quality sensor, so it automatically adjusts the settings to the current air quality. The air purifier has a HEPA, carbon, and pre-filter. This way, you can remove odors, allergens, viruses, and fine dust from the air. Do you need to replace a filter? The PH04 will notify you. The Dyson Purifier Humidify+Cool Formaldehyde PH04 360 rotates 360 degrees, so it provides the entire room with fresh air.

Improved filter technique
The Dyson PH04 has a fully closed system. This way, it meets the HEPA 13 norm, so the air doesn't escape before it's purified. The completely airtight HEPA 13 filter system can filter 99.95% of all particles from the air, like ultra fine dust, dust, pollen, allergens, and viruses, as small as 0.1 micron.

Dyson Link App
You can stay up-to-date with the air quality in your home with the Dyson Link App. On this smartphone app, you can see the current reports of the air quality and the remaining lifespan of the filters. You can also use the app to control the air purifier remotely.

Improved and thorough cleaning
You can clean the PH04 with the push of a button. This monthly deep clean cycle easily removes bacteria and limescale from the water system of your Dyson air purifier.

  • no noise

  • man no longer snores !!

Nice breeze in the bedroom almost without noise. Since we have that thing in the bedroom, my husband no longer snores at all. Unbelievable but true. Probably too dry air??!! Had I known this I would have bought the device 10 years earlier.

Dyson Purifier Cool Formaldehyde helps me with my allergy

  • controllable via app
  • very quiet
  • sleek design
  • pricey

I was so happy to pick up the Dyson Purifier Cool Formaldehyde. First I wanted to test it in the bedroom. I have a house dust mite allergy and was very curious if the Dyson would help me to have fewer complaints. I often wake up with a runny nose and swollen eyes. I installed the Dyson in no time. The filters click into the device very easily. And then immediately downloaded the app. Since the dyson is in the bedroom, it is very convenient that I can operate the dyson comb from bed with the app. No more getting up to put it on night mode. After a few weeks of use I can report that I really notice a difference in my allergies. When I wake up I no longer have itchy eyes and I can breathe freely. What a relief...I can smell and taste much better because of this. At night, the Dyson gives off a cool breeze and is virtually silent. After this success I will certainly also use the dyson in the living room. You hear more and more often about the level of the harmful substance Formaldehyde in almost all our household items.

Really bad for such an expensive device

  • Filters
  • Build quality!

I replaced my Rowenta 2 in 1 Ecplise for this unit. This was unfortunately a very bad choice. I was under the assumption that a device with such a high price tag would have extra added value, nothing could be further from the truth.

When I unpacked it, I noticed that the build quality is substandard. The two buttons on the side to open the filters beep on all sides. You do not expect this for such an expensive device. In addition, the filters do not connect well to the device and the on/off button is simply mounted crookedly. In addition, the device falters and the plastic material looks/feels very cheap.

Then turn it on. It looks like an Airbus is taking off in the living room. If there was also just as much flow, that would still be fine, but the airflow is very disappointing. So for the fan functionality, you don't have to buy it. The Rowenta I had did this many times better and quieter.

You can also clearly hear a certain kink sound while rotating. Very irritating, especially at night.

Thought I'd never say this, but this one is going out and I'm repurchasing the Rowenta again. Value for money is all around worthless.
