Charcoal Bags Odor Absorber (Large, 4 Pack, 200g each), Nature Fresh Bamboo Charcoal Air Purifying Bag Activated Charcoal Odor Absorber for Home, Closet, Shoe, Car Odor Eliminator Freshener Remover

Was very happy after one day the odor was gone. Very pleased with this product it came with hooks for hanging anywhere.

This product is excellent. I used them in my garage. All of the musty garage smell is gone!

It works to rid odors but the smell at first is not good. It takes a few days for the smell of the product to go as well.

The smell of charcoal smoke overpowering. I have asthma so I couldnt keep product to see how it worked.

It didn’t come with the hooks that it states it will have

We used these in our closet that has our dogs food/treats and my husbands stinky running shoe closet- works instantly!!!!!!!

It seems to be working..

I think its working

Rejuvenate For Up To 2 Years ... in the sunlight for a couple of hours I can find absolutely no scientific evidence that UV light has any effect on activated carbon. I measured the amount of UVA and UVB light that gets through the double layer bag holding the charcoal: in direct sunlight, producing 262 microwatts/cm^2 the bag blocks all but 39 microwatts/cm^2 (only 15% gets through). The top layer of charcoal would stop any light from reaching anything below. The standard ways to regenerate activated carbon are: Regeneration / Active Carbon Activated carbon is an expensive product. In most of the cases the cost of replacing the saturated carbon would be prohibitive. It should therefore be regenerated, and four methods have been developed for this purpose: Steam regeneration This method is restricted to regenerating carbon which has only retained a few very volatile products. Thermal regeneration By pyrolysis and burning off of adsorbed organic substances. In order to avoid igniting the carbon, it is heated to about 800 °C in a controlled atmosphere. This is the widely used method and regenerates the carbon very well, but it has two disadvantages: it requires considerable investment in either a multiple-hearth furnace and it causes high carbon losses. Chemical regeneration Some process based on the action of a solvent used at a temperature of approximately 100 °C and with a high pH. Biological regeneration This method of regeneration has not yet been applied on an industrial scale.

Does what it is supposed to do and starts the minute you hang it on the supplied hooks.
