Hallo again
I'm with Desperate on this - where on earth does Mr Dyson find so many lovely folk to work in his rather James-Bond-villain-like HQ?
They were all very charming - enthusiastic about their work, but with a healthy splash of Brit self-deprecation. And they made all the science-y bits understandable to us layman.
We found lots out, including the revelation that cats sweat and it's that - along with their saliva - that us allergicy types often react to, rather than their hair. Apparently, lots of offices have cat allergens lurking in them because the bits transfer from cat-owners' clothes.
We got to see some dustmites under the microscope (euwwwww) - I didn't realise that you can freeze the little blighters to death. So our freezer now resembles an Arctic teddy bears' graveyard, as several of DD's favoured toys are having their mites frozen off.
There were lots more tips - a good one was to move your furniture around now and then, as mites love to live in the comfy darkness under the sofa and moving it round annoys them. But if you're loath to move stuff as it will reveal those little indents in your carpet, a strategically placed icecube will help your carpet spring back into shape.
And you're not safe from the critters if you have a hard floor - they can live happily in the dents in floorboards, laminate etc. Seems to me the hardy little fellows will be best placed to survive the end of the world tonight!
Another tip was to avoid using wet cleaners on your carpet - although you think you're giving it a good clean, some of the moisture will remain at the bottom of the carpet, giving our little dustmite chums the perfect conditions for life.
Ummm, hope those tips help!
So thanks again Dyson and Mumsnet.
