Don’t slag off Dyson’s Airblade, slag the germs off your hands first

If your hands are washed clean, there’s no germs to dry off anyway

Brilliant piece of kit, Dyson’s Airblade hand dryer. First time you see it, you think  wow amazing.  The same when you use it.

Which kinda has us jumping up and down when we see a bunch of technology wonks have published research to say it spreads germs 1,300 more than paper towels.

A good idea world-wide

For starters, if it was that rotten, the giant Mitsubishi Electric Corporation wouldn’t have rushed out their own high speed Jet Towel, would they? A good idea is a good idea – and imitation is the sincerest form of flattery. And don’t knock it because it’s Japanese, they turn good ideas into the best in the world.

But right now it’s Dyson that’s taking the flak – our own world-leading brilliant technology company. And frankly in our view, these Westminster University researchers  claiming the AIrBlade spreads germs aren’t doing any of us a favour.

First off, the machine is a hand DRYER, right? The whole premise of its design is that hands might be wet, but they have already been cleaned. THERE ARE NO GERMS TO BE BLOWN OFF.

Unclean, unclean

So if the Westminster Uni  people found the thing spread germs, their hands must have pretty dodgy in the first place to have spread so many.

Yeah, well. Why are we not surprised? If they were basing their research on the typical behaviour of real people – which they should have – their hands were laden with all kinds of gunk. Here’s why.

Uh huh. The germs got spread because the hands weren’t clean.

End of.

Sure, lots of tiny drops of water would have spread around the place. The thing is basically a fan, for goodness sake – that’s what fans do. And Dyson’s jobbie blasts air at 430 mph – you don’t send a boy to do a man’s job.

Drops of CLEAN water – the hands were supposed to be properly washed first, remember? And Dyson’s dryer only blasts clean air because it’s sucked in through a HEPA filter before it gets to your hands anyway.

Which means microorganisms down to only 3 microns across don’t come anywhere near you – one heck of a lot better than paper towels.

Paper towels anyway are really compensating for poor hygiene in a non-touchless environment.

Touchless hygiene

If a washroom has Dysons installed, it probably has no-touch infra red taps too – and soap dispensers. The only contact is hand-to-hand scrubbing and rinsing – which done properly should ensure all the germs go down the plughole.

Most people are incredibly wasteful of paper towels anyway.

As Joe Smith points out in his superb hand washing video, in America 13 billion pounds of paper towels (5,9 million tonnes) are used every year, just to dry hands.  571,231,000 pounds of that (259,106 tonnes) is wasted by people fumbling around, not thinking what they’re doing.

Why all this hoo-hah about washing hands?

Because in our Twenty-First Century always-on-the-go, digital world, clean hands are often all that’s between us and coming down with any number of bugs like norovirus, escherichia coli, salmonella, clostridium difficile, campylobacter, MRSA, or simply colds and flu.

Finger food, fast infection

Look no further than our favourite choice of food. Burgers, chicken drumsticks, hot dogs, pizza, sandwiches, wraps, tamales, tortillas – all eaten with fingers. Now ask yourself honestly, when was the last time you washed your hands before you ate? Not really on the radar when you’re out and about, is it?

OK, so now wash your hands – the way you’re supposed to, with enough time to sing Happy Birthday to yourself twice. And now dry them off with the Dyson. No worries, right?

Hey, hey, hey! 430 mph of clean air. Now you’re really cooking with gas!

Wash your hands, yes – but dry them safely?

Girl with soapy hands
And for your next trick – how to get them dry safely

You’ve done the whole thing – soap and running water for two minutes, the backs of your hand too, and in between the fingers.

Phase One complete – exactly the way we’re inspired to by those hygiene experts at Northampton General Hospital.

So now your hands are dripping.

Clean, yes – but with residual germs contained in the water drops.

Which means Phase Two – removing the moisture AND the residual germs.

Where’s the drying doohickey?

If you’re at home, there’s probably a towel within easy reach – a fresh one, because you’re that kind of person.

That’s OK, as long as you only use the thing once. Wiping your hands gets rid of the moisture – and has a certain scraping action that gets a lot of the germs off.

But now they’re on the towel which is already moist and at room temperature. Perfect for germ reproduction, which they will certainly do, doubling in number every twenty minutes or so. Chuck it in the laundry and they’ll get sorted.

But put the towel back on the rail to be used again and you’re setting yourself up for re-contamination. You wash your hands again and a whole load of new germs arrive just when you think you’ve got them clean.

Uh, huh. You’ve gone backwards.


Better if you’re in a hotel of course. Fresh linen every day, so it’s use once and chuck. But have two showers, one in the evening and one next morning, both with the same towel and… you guessed it – you’ve re-germed yourself again.

How about elsewhere? Public places, shared washrooms, lines of loos and hand basins and – gasp – other people.

Keep your eyes open, what you’ll see will shock you. Like around half of everybody busily pushing through don’t even bother to wash their hands. Weirdly, some of them will even look like they’re going through the motions – actually standing at the basin – but not physically doing anything.

Why is this, people all in a rush? The place might be done up nice, but it’s hardly where you’ll want to linger. No plugs in the basins for a start – though that’s a good way of compelling you to use running water.

I don’t wanna queue

There certainly IS an issue with hand drying. If the place gets anywhere busy, like Saturday morning at a shopping mall, there’s ALWAYS a queue for the towel dispenser or air dryer.

Right there could be one reason people don’t wash – they see the queue and stump out of there in a late model huff. Another sub-group avoid the queue by wiping their hands on their clothes. Let’s hope neither of them are going to sit down and have a meal with their hands like that.

Could also be the drying method puts them off. Plus the six to ten steps across the floor to the drying thing with your hands dripping, before you can even start.

The yuck method

It’s dying a death now, but the old cloth roller towel dispenser is still around. You know the one – where you grab both edges of a section previously used by someone else to give yourself a fresh piece, pull down hard and then wipe.

Yes, it gets your hands dry – but there’s a good chance you’ve got somebody else’s germs in using it. And the somebody after you gets yours.

How about a paper towel dispenser?

Fiendishly difficult contraptions to operate when your hands are wet – jamming, bunching up, or refusing to dispense all together. You get your hands dry alright, but usually with a wodge the size of a football before you’ve finished – and requiring a dexterity level at least on par with those amazing technical ladies who solder miniature circuit boards.

Despite all this, paper towels are undoubtedly the safest. Use once and throw away – brilliant in principle.

The turbo-blaster

But technology’s not finished with you yet, because there’s also the air dryer. Either a weak buzzing machine that does nothing, or a force-feed jet blast from a supersonic wind tunnel. Yes, you’ll get you hands dry if you wait long enough – though it will auto shut-off at least five times before you do.

Uh, huh. Check the floor underneath. A lot of people like you dripped for several minutes before the drying became effective. And have you noticed how humid it always seems to get in there?

A lot of water drops are being blasted off into smaller germ-laden droplets and spreading throughout the room. You walk in to go for a sprinkle – and walk out with a dose of flu.

King of the dryers right now is undoubtedly the triple whammy air blade dryer. Pioneered by the Dyson people, who are all totally brilliant. But again, not designed for someone with dripping hands.

Check the floor of the compartment underneath where you put your hands in though – there’s usually a pool of water. Look at the walls alongside and you’ll see damp squidges radiating out – airborne germ clouds, just like the other jobs.

So what to do?

Hygiene magic

Lucky for all of us, there’s a guy called Joe Smith who has it all worked out. Shake your hands after washing, then dry them with a single sheet of folded paper. Check out his video on TED – if nothing else, his charisma will have you remembering how to get your hands dry safely for ever.

Joe’s mantra is SHAKE your hands to get rid of the drops – then FOLD the paper to give you enough absorbency to remove the moisture. Try it, it works – big time.

But there’s still the problem of acquiring your piece of paper in the first place. Joe has them all primed and ready. But you will have to battle with some kind of dispenser – and with wet hands as we’ve seen before, you really need to be Fukimoto-san, high-tech solder expert.

There is however, a way out. To reverse Joe’s mantra and do it backwards: first FOLD, then SHAKE.

Fold, as in have the single sheets pre-folded in a dispenser you can extricate them from with wet hands. NONE of the existing ones on the market allow you to do this with any ease.


OK, so have a cup of coffee while you think about it – at Costa’s, where they seem to know a thing or two. Including – though they don’t know it – how to get your hands dry.

Because the paper napkin you take to your table is already pre-folded into four – and easily accessible, packed loose in an open-topped container along with the spoons, sugar, straws and stir-sticks for you to help yourself.

Picking up one of those without lifting a whole fistful is a breeze. So if your washroom had a box of those on the vanity slab beside each basin, it would be a doddle.

No more trudging to the dispenser or dryer, dripping on the floor. The FOLD is already done. You SHAKE your hands, keeping them in the basin so all the drops stay in the right place. Then you pick up a sheet and dry your hands. Clean, dry and safe, because all the germs go in the bin.

Back to Earth

So why all the rigmarole with expensive machines that don’t really work?

Search us.

Though the legend is not lost on us that when the Americans sent the astronauts into space, they spent millions developing a pen that would write in a vacuum, upside down if necessary, and on all surfaces.

The Russians gave their cosmonauts pencils.

Paper, scissors, rock – paper wins.
