Initial situation

So far we have used various devices in our household that were active around the topic of air. On the one hand, a humidifier was used from time to time in winter, and a fan and / or compact air conditioning system in summer. With the increased home office I wanted to buy something for air purification for a long time, with the Dyson Pure Humidify + Cool there was now a device that should replace as much as possible. In the winter it is mainly used for cleaning and humidification and in the summer it is more likely to be used for cooling.

The optimal humidity is 24 to 50 Percentage of relative humidity, while a room temperature of 20 to 21 Degree in the living rooms and 18 degrees should prevail in bedrooms says the BAG. It is generally very dry here in winter, on the one hand because of the air outside that flows in when airing. On the other hand, however, also through the heating, which warms the air but also dries it. The consequences of this are probably familiar to some of you, especially after sleeping, a sore throat, dry nose and watery eyes indicate air that is too dry.

Structure & setup

A Dyson device is always a pleasure to unpack, packaged well and neatly, and as an engineer, you enjoy well-thought-out products. There’s not much to set up with the Pure Humidify + Cool. A few more adhesive strips have to be removed and the over 90 cm high and 8kg heavy tower erected. I then immediately filled the water tank, which has very practical rollers for moving in and out, as well as a handle. This shows that Dyson has thought through the product.

The possible connectivity then of course suits me anyway, so you can simply connect the Dyson Pure via the Dyson Link app and then there are numerous options for operation and measurement.

Dyson Link App

In the app mentioned, I have displayed air data from my place of residence via a weather service and the data from the Dyson Pure Humidify + Cool below it. If the values ​​get bad, the house turns yellow / red / orange tones. In the app I now have the option of reading out the data from numerous sensors, on the one hand as 24 h Resolution of single days or as a weekly overview. I can query this data for a general assessment of the air quality, as well as for individual measured values ​​such as: PM2.5, PM 10, VOC, NO2, temperature and humidity.

The fact that the Dyson Pure also measures itself has numerous advantages, namely that I can run automatic modes in the operation. At the bottom left of the app’s home screen, the device can be operated as with the included remote control. You can not only reverse the air flow but also spread it more widely and let the device run in automatic mode. It is cleaned and moistened to a target value and then the performance is reduced or increased if necessary. Ideal when you sleep and the device takes care of the good air.

Dyson Pure Humidify + Cool in action

I used the Dyson Pure Humidify + Cool in different places to find the best place for us. In the end, I found the Dyson to be the best in the corridor, so it could ventilate all the rooms and better circulate the air in the house. By the way, if you want to use the Pure directly in the bedroom, I recommend the distribution mode. The air is diverted through the rear of the air amplifier. The advantage of this is that you are not directly exposed to a stream of air and the whole room is still cleaned and humidified.

Which is amazing and also shows how dry the air is here. I have to refill the water tank every 2-3 days, even though it has a volume of 5 liters. Dyson states that with continuous humidification at level 1, the tank 36 h holds. My humidification is set to automatic, I’m amazed and the more humid air is definitely good for us.

What I currently find difficult to judge or measure is the filter function in the Pure Humidify. On the one hand, the built-in HEPA and activated carbon filter, in this should 99, 95% of the ultra-fine dirt particles up to a size of 0.1 micrometers, including allergens, bacteria and pollen, are absorbed. I am curious about this effect, especially in the pollen season from spring, to see whether my situation will improve. On the other hand, the water that is used for humidification is first cleaned
with the help of UV-C light. This means that up to 99, 9% of the bacteria in the water killed.

I was a little amazed at the size and dimensions of the Dyson Pure Humidify + Cool when I unpacked it. The previous humidifier was just a third as big. But Dyson always makes visually beautiful products and so the tower doesn’t bother me. I find the Dyson’s fan noise very pleasant and quiet, also ideal for sleeping. Since it combines several devices and relies heavily on filter function and air quality, such a device is worth investing more in.
