I keep a pot of water on my stove to steam for moisture all winter. If I pour half a box of red hots in, my house smells like spice. Lemonheads give a clean lemon scent. Of course, there is the option of cinnamon sticks, potpourri, and oils, but these candies are SO CHEAP! I’ve also heard of sticking a dryer sheet in the water…but I’ve not tried it…any one else?
