"Room fragrances are designed to mask or freshen the existing odor while odor eliminators do exactly that, get rid of odor," says Nelson. "Many fragranced products contain chemicals that release VOCs which can have negative effects on your home's air quality and your overall health. Some great natural solutions to this are fragrant houseplants, simmer pots, or charcoal air fresheners." You can also look for odor eliminators that contain natural ingredients, such as activated charcoal, that can absorb odors from the air. Some odor eliminators also contain enzymes that eradicate a smell at the source rather than simply covering it up.
