My house is 12 years old and when i enter the house it has
a dusty smell, I don't know where it is coming from. I have a
cellouse attic insulation, my carpets is 12 years old I got it steam
cleaned, I got my duct cleaned and i use good furnace filter and replace
it every 4 months. does the cellouse insulation in attic
cause this, if so, how can it pass through the drywall and what can
i do about it or is there something else which can cause dusty smell
