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

Ive recently moved in to a house with pretty heavy smokers with 4 large dogs and didnt want my clothes to smell of smoke or dog. I hung up two bags in my closet and have to say they work great, the rest I hung randomly around my room but I still had to buy a real air purifier for any actual change. They arrived on time and are exactly as shown.

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

Good product. I used it after my wood floors were painted due to my son needed to sleep in his bedroom and I didn’t want him to aspire the odor and it worked. This type of Smells could last for at least 2 or 3 weeks. By day 5 none! I would buy it again.

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

I just bought a new to me car and the previous owner was a smoker, the car smelt horrible, but put two of these charcoal bags in and a couple air fresheners and it’s just like new

I CANT TELL A DIFFERENCE, WAITING TO ASK MY GRANDCHILD, SINCE SHE THE ONE THAT COMLAIN.

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

I havent had these long at all so I cant really give a full review yet but they seem to be doing pretty well so far.

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.

Good stuff.
