Here in the land of the frozen tundra... and frozen everything else... we have issues with dryness. When the air is bitterly cold, it doesn't hold much moisture. So 73% humidity at -30C is much, much drier than 73% humidity at, say, +2C.
And because most houses are heated with forced air furnaces, that heat dries what little moisture existed completely out of the air. My programmable thermostat has a humidity reading on it.... well, it used to, but now just reads low. I have seen it at 14%, so I am assuming that the cut off is 10%.
So, to combat the cats getting their noses zapped with blue sparks (ow!) everytime they sniff something, and the chronic nosebleeds that tend to occur when all your mucous membranes are dessicated beyond belief, I have some up with a high tech solution. I don't have the funds to have a central humidifier installed on the furnace, so I had to be creative.
I think I will have to apply for a patent on this invention. I call it the "Manitoba Moisture Maker".... what do you think? Will I get rich from it?
