The Classic Smell Killer from Frieling stops bad odors in their tracks. While the smell killer rests in its bowl of water, it removes bad odors by causing the odor molecules to disintegrate. The result is totally natural odor elimination that freshens any room up to 170 square feet. Great in the kitchen, bathroom, or any room that you want to smell better. It is also useful for cooking - just place it by the sink and use it like soap to remove fish, garlic, or onion odors from your hands. Guaranteed to work as long as you own it.
