Long-Term, Safe Odor Elimination System for Musty Rooms/Carpets

The user is struggling with a severe musty smell in an old dorm room carpet, having tried steam cleaning and then excessively applying eucalyptus oil, leading to health concerns. This points to a demand for a highly effective, safe, and potentially long-lasting odor removal solution, particularly for deeply embedded smells in old carpets or enclosed spaces where replacement isn't an option. This could be a professional service, a powerful but non-toxic product, or an 'odor-bomb' kit specifically designed for deep penetration and neutralization without harmful residues.
