2 pounds drying indoors? Yikes, it would take a hella filter for that. One thought to keep the odor down indoors is to place a fan in the window, blowing out as an exhaust fan. The most effective way is to place a box fan in the window against the screen and secure it somehow. Then, fill is the part of the window that is not covered by the fan with cardboard, being careful to make it fit well. With the fan on it effectively creates a negative pressure in the room, and will draw in air from the house and blow the odor outside. Good luck!
