What is the absolute best odor eliminator?

What is the absolute best odor eliminator? The absolute best odor eliminator depends on odor source, as different products work best for different smells. For general household odors, top-rated options include activated charcoal bags that absorb odors, baking soda that neutralizes acids, white vinegar that neutralizes, and enzymatic cleaners like Nature's Miracle for pet urine that break down proteins causing smell. For paint, primers like KILZ Original oil-based and Zinsser B-I-N shellac primer are considered best odor blockers for smoke, fire, pet, and musty smells on surfaces, sealing odor into surface rather than masking. For air, HEPA filters with activated carbon, ozone generators for severe cases used professionally, and odor absorbers like Ozium are strong. For smoke damage, shellac-based primer is generally considered best, better than water-based. For pet odors, enzymatic cleaners plus sealing primer work best. No single product eliminates all odors, combination of removing source, cleaning, ventilation, and sealing is most effective. For surface stains causing odor, shellac primer is often rated best, while for airborne odors, activated carbon and enzymatic cleaners are top.
