Dyson’s Pure Hot and Cool Link is a fan with heating, air purifying and an app. Its claim to fame is that it captures 99.95% of airborne allergens and pollutants.
GadgetGuy has been reviewing the fan for the past few weeks and like everything Dyson can report that it meets or exceeds expectations for design and build.
But there are a few things you need to know before investing A$799 for this device.
Before we kick off let’s get one thing straight – fans do not cool air. They help to distribute air around a room (hot air rises and cool air falls) and in blowing air over you may produce a slight cooling effect if you are sweating.
To labour the point if it is hot all they do is blow that very same hot air, and you need to think more closely about your cooling needs. For example, do you need air conditioning (portable, split system or ducted), evaporative/personal cooling, or will a fan suffice?
On the other hand, this fan has two differentiating features
- An integrated air purifier filter to improve air quality
- A built-in heater that we briefly tested (it is a hot summer here in Sydney)
The air we breathe contains microscopic particles of dust, allergens, pollen, gasses and more. On the whole, Australia has clean air compared to Beijing and other places where cars and coal burning power stations are prevalent.
As the larger particles settle out of the air in your home, you see this in the form of dust on tables. These are a mere annoyance – the smaller ones do the damage via hay fever, itchy eyes and allergy.
Dyson’s purifier uses a Glass HEPA borosilicate microfibre that traps particles down to 1.0 micron. It also uses activated graphite (carbon) to absorb gasses other than “air”.
The A$99 filter needs to be changed when it is full. The app tells you when – typically every 4,300 hours or less if you are in a dirty air environment.
But there is a slight catch you need to be aware of. It only cleans the air that it sucks through the filter. That is fine in an enclosed space with windows and doors shut – eventually, it will have sucked all the air in the room through the filter.
But if you open the window or door or are in a large open space it cannot suck enough air to clean it all.
As a purifier, it is useful although dedicated purifiers (not a fan or heater) like the Inovaair AirClean A7 at $595 cleans down to .3 microns and has a longer three-to-five year filter life for $130.
As a filter/purifier for medical reasons, there are better, dedicated air purifiers at a lesser cost.
