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

I bought the 8 pack and had high hopes but alas, I think this was a waste. Ba humbug!

I have an enclosed area where 2 dogs are daily and I hung 3 of 4 bags and it’s not taking the odor away. Thought it was supposed to purify the air somehow.

Put them out and the odor was so horrible as if 30 people were smoking in my apartment for hours tried to tolerate for 5 + hours was nauseous threw them away double bagged to avoid embarrassment I’m sorry but truth maybe in large home basement or attic Although product was not used was offered full refund for my inconvenience manufacturer takes pride in product BRAVO!!

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.

Mold and mildew from water damage

Really did the job. Very pleased. Good product.

I got this for my apartment which smells constantly of mold/mildew, smoke and cat litter. It really helped with clearing those scents out. I’ve had it for a few months now and it still seems to be doing the job. Idk how long they last but seems good to me still

I used this in a cedar chest that had mothballs in it. this product is slowly (fortunately) getting rid of that mothball smell. I never thought to use this in the refrigerator, but it works well! Better than baking soda!

Seems like it is working cooked fish for dinner and absorbed the smell

This is my second order of these and Ill probably be making several more. Im putting these in every room of the house, and gave some to my adult kids for their homes. You will immediately notice a difference in your breathing! The air is fresh with no irritants! I have bad allergies, and usually sit at my desk blowing my nose frequently. But since Ive put these in, I no longer have that problem! I put two of them by my desk. My kids say they made a difference too! You dont want to snooze on these!
