MOSO NATURAL Unscented Air Purifying Granule Bag Odor Eliminator For Cars, Closets,Bathrooms And Pet Areas 200-gram (Charcoal color), Long Lasting Charcoal Bag | Lasts up to 2 years!

It is as small as a normal phone these days, and can fit anywhere, may it be your car or study room. 1 piece is good for single normal room. It is non-electric, purifies air & is good for pocket too. Besides electricity saving, I like how it works naturally, saving our body to inhale from otherwise perfumes. Charcoal does show its effects, though its level of effectiveness is not yet measured, but call-it-anything, I did feel better with the air I inhale. At least, I inhale less pollutant air than others now.

Expensive

As it mentions, this is a natural air purifier and doesn't have any odor.We use our car to get back home after a workout and it uses to smell of sweat earlier. After placing this in the car, there is no more bad odor and it feels fresh to be in the car while going to office :)

Did not fully get rid of that musty smell in a parked car in monsoons. In comparison, moisture absorbers like absorbia etc work much better, though inconvenient to store. Won't be buying again.

Not so effective. Overated .

Was struggling for a perfume for my two cars which were not smelling good. Tried from local perfumes to imported ones. The car smells good until the scent is present and later the same issue. Came across this product through YouTube and recommendations from many car experts. Bought it for my cars and within three days, the smell of my car has been neutralized and don't have the bad smell and it has been completely absorbed. Looks like I have found my product and also it can be used for two years by keeping it in sunlight is another biggest advantage.

Its truly an amazing product... Tried for first time and surely recommended

I purchased this for my car after cat litter got stuck in my carpet. The smell of cat litter was very strong. With this odor eliminator I can no longer smell anything, it is great! I was really worried that it wouldn't work, but it works wonderfully. I just put it in my back seat and there are no more odors in my car.
