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 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

After about a week of use I cant tell that much of a difference. I mean I smell the bamboo charcoal slightly, but I can also still smell other odors that I was hoping to be removed.

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

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.

I was taken aback by the smell of the actual product when I opened the bag BUT they eliminate offensive odors and that scent dissipates quickly...I will be recharging them in the sun in 2 weeks but I believe they will hold up like they say they will.

One in each room. Fresh but not fake.

Too soon to tell.

The jury is still out on the efficacy of charcoal bamboo and Im comparing this product to another with different features but I really want them both to work of course! I need to offset off-gassing of other products and for mold and mildew which they both claim to do. The company is based in the USA and has some other interesting items Im willing to try and their mission sounds great but I think the products are both imports. This one comes with hooks but they were too small to hang under sink on the water pipes so Ive used my own. The other company suggests to take out the inner bag and put in sunlight to rejuvenate or activate the charcoal, this one you cant because its sewn shut. We shall see. Imma put one in the fridge to really test it!

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

No flaws, arrived promptly. I purchased for a senior who has a cat, and needs help with odor control.
