EnviroKlenzDeodorizer Block | Odor Neutralizer for Small Spaces, Fridge, Car and Bags (4.9 oz) | Unscented Air Deodorizer | Odor Eliminator For Strong Odor For Home | Lasts Up to 6 Months

I used it in my car to help with a musty smell, and it seems to have made an improvement. However it looks like when it arrived some of the powder leaked into the packaging, which makes me a little uneasy about leaving it in places it might get on the fabric. I guess 3 stars for doing what it says, but at the end of the day I'm probably still going to hit my car with a Ozone generator or something to clear it out. Probably good for more casual space application.

Wanted this product to help remove odors in closets .. bc of having MCS.. The product itself had a strong odor although it says NO FRAGRANCE.. It arrived w/ the ingredients inside broken!! Not impressed!!

I got this to put in my cat's litter box. I have a high domed top litter box and I thought I'd mount it to the inside of the top to help with the odor. But it comes with no adhesive, peel off or otherwise, and no hanger. I had to use some nano tape to mount it to the inside lid of the box.As far as odor reduction, I'd say maybe 15-20%. A slight improvement, noticeable, but not great. Considering how small my litter box is, and that the odors are mostly contained in that small space, I was disappointed that I didn't get more improvement.
