Dyson’s Humidifier guarantees* eternal youth

*Well, eternal-ish. The AM10 could at least make you healthier and less scaly-looking

The Air Multiplier's back! It still looks like a portal to a parellel universe.

The only parallel universe this Dyson fan-based contraption is a portal to (if any) would be one where everyone’s a little less sneezy and has nicer-looking skin. You see, the AM10 Humidifier is not just a device that bathes you in cool air, but a device that bathes you in air that supposedly has just the right level of humidity to maintain your skin’s, nose’s and throat’s health.

So it doesn’t just blow?

No, this time it blows actual stuff - that stuff being mist. On top it’s the usual Air Multiplier setup - a loop with a fine aperture running around its circumference through which air is forced at speed, blasting the air in its middle around the room. The difference this time is that there are two apertures, and the air coming through the rear one also accelerates ‘nano particles’ of water as they emerge from the front. 

These particles come from a 3l water tank that sits at the base of the Humidifier. The water is exposed to UV light to kill a claimed 99.9% of bacteria within it, before being vaporised by a piezoelectric transducer flip-flopping at 1.7MHz. Then it’s mixed with the airstream and out into your room it comes.

Sounds cool. But… why?

There’s a weight of research that suggests living in conditions with the right relative humidity (between 40 and 60%) is better for you. If relative humidity is too low, the air absorbs it from other sources, such as your human flesh. Your eyes can get sore and your throat and nasal passages can get irritated, and the membranes that normally block airborne baddies (viruses, hayfever and asthma irritants) become less effective. What’s more, skin driness has been correlated with increased instances of diseases such as eczema and dermatitis.

Research also suggests low relative humidity can make you look old and scrappy. It’s linked to increased fine wrinkles, a lowering of skin elasticity and scaliness. All in all, too little water in the air sounds like A Bad Thing, and the Dyson Humidifier is supposed to make sure there’s enough of it - and it has an auto mode to keep it at what it reckons is the best level for you, for up to 18 hours per fill.

But we live in a soggy country. What if my house’s ceilings are dripping with moisture and my walls are wetter than a trout on holiday in Wales?

No help from the Dyson. You’ll be after a de-humidifier instead. But even here in damp old Blighty, low relative humidity is prevalent at this time of year, as our passively-heated homes take cool air from the outside and make it hotter without adding the extra moisture it then has the capacity to carry.

Does the Dyson work?

At this stage we couldn’t possibly say, but there are good reasons to suspect it might given the accreditation it's received. And in any case, it looks like a portal to an alternative universe, plus it also functions as an Air Multiplier fan - and we know they work rather well.

Got a spare £500? It’s available now in John Lewis and through Dyson’s site, though for best results you’ll want one for each bedroom and living space in your home - and that could get a mite costly.
