Actually, products that just mask odors with fragrance often end up smelling even worse later on because the scents mix. But I really loved this one because it works by directly eliminating the bad odor. A subtle cotton scent lingers pleasantly, and it isn't a harsh, nose-stinging scent; it feels really mild yet definitely takes care of the smell. Above all, since this is a space where my whole family lives together, I was most concerned about the ingredients. They say it absorbs and eliminates everything from invisible bacteria to harmful substances associated with sick building syndrome. It is eco-friendly, certified for atopic dermatitis, and made from food ingredients, so the most reassuring thing is knowing that you can use it with complete peace of mind, even in homes with children or pets! It’s great to place anywhere in the house, but I tried using it in the bathroom, which was a particular concern for me. ✓ Since we live in an older ground-floor apartment, the sewer smell rising up when the weather was bad was a real source of stress, but after using this, I can definitely feel that the unpleasant smell has significantly decreased, so I am extremely satisfied. For those of you who are concerned about odors throughout your home, especially if you live in a building like mine and suffer from sewer odors, I recommend giving it a try without hesitation! The air is fresher, so I feel better every time I go into the bathroom these days.
