I was watering my plants on top of the china cabinet...and I turned my head and saw the fan blades from the cieling fan. They had a layer of DUST on them. Along with all the other upright fans in the house. Along with everything else catches dust. How do I stop, or reduce the ammount of dust in my house? It's kind of gross thinking during the night i'm inhaling dust from my bed-side fan that blows on my through the night, which it's blades are dust covered. Anyone?
