These little Nebulisers.

They say put water in the bottom bowl, insert medicine cup with your preferred 
medication, then turn it on.  I guess it heats the water up, but, is any of 
that water going to mix with my EIS?  Or does it just heat something up 
independently to the medication?  The old Nebuliser I have had for years 
doesn't take any water, so how do these little things work?

Yeah, I know, I'm a dumb_rse, so humour me.  The little 'manual' talks about 
heat, which I guess is the water being heated?  I don't want to dilute my EIS.  
My old one, you just put the medication in a little cup, turn it on and it's 
good to go.
