Charcoal Odor Absorber for Strong Odor (6 Pack, 100g each), Bamboo Charcoal Air Purifying Bag, Basement Musty Odor Eliminator Deodorizer, Activated Charcoal Odor Absorber for Closet, Shoe, Car

I left a vegetable in the veggie drawer when we went on an extended vacation. We always dump our ice cubes (side-by-side, built in fridge), and I was surprised that they tasted 'funny' the next day. Then I noticed a chemical/medicinal/weird smell every time I opened the fridge door. The power had gone out for 4 days in-between. Well we cleaned it all out--I mean EVERYTHING, including cleaning labels of bottles, etc. And by "we", I pretty much mean my husband did it all. The smell/taste stubbornly remained. We put a bowl of baking soda in the fridge--no luck. Then I got these and *bam* - smell was gone. Fridge saved!! These can be "recharged" by putting in sunshine for 1/2 hour too, so they will last forever, and they fit nicely wherever I put them. Worth every penny for sure, so easy to use (although I doubt they'd have worked without cleaning.) I have some in another place and they work there too so good quality, have recharged previously and they do continue to perform. Even come with hangers when needed. Highly recommend~!

These work. Simple as that, they work. My daughter‘s bedroom had a musty smell for 15 years. I tried everything. I tried raw onions we even had it repainted. I put baking soda under her bed. Nothing worked. I bought these and within a day the smell is gone. My bedroom also had a yeasty smell. I googled it and it said it’s probably some type of fungus. Tried everything…cleaned like a mad woman looked for mold. Cleaned all the shoes in the closet. Did everything and nothing worked. Our bedroom still smelled like bread. Bought these and put them around in the closet. All the smell is gone. They are 100% effective. I can’t believe I’ve never knew about these before. You can smell absolutely nothing now when you walk into my bedroom and my daughter’s room. Nothing there’s no order whatsoever. The bread smell is gone, and the musty smell in her room is gone.

I placed these bamboo charcoal bags in my basement, closet, and car, and they really work to reduce musty and stubborn odors. Unlike chemical deodorizers, these feel completely natural and safe, which is a big plus for my home environment. Each bag is a good size and lasts a long time — I’ve been using them for months with consistent results. They’re easy to refresh by placing in sunlight every month or so, which helps maintain their effectiveness. I appreciate that they’re reusable and eco-friendly, making them a smart choice for ongoing odor control. Tip: Place them near air vents or in enclosed spaces for the best odor absorption. Highly recommend for anyone looking for a chemical-free way to keep their spaces smelling fresh.

"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.

Used them in old dressers from estate sale. They worked perfectly. One in each drawer. They took out the musty old smell.

This product seems to be a good quality product, I am very pleased with the purchase.

I moved into a beautiful apartment across town where the rent is expensive and the communities are gated. However my neighbors cook curry 3 times a day. I’m sure the smell is good in their home but by the time it seeps through and enters into my home, it smells foul. It’s a terrible odor, it doesn’t even smell like food by the time it reaches me. The place where it enters my home is threw my master bath and master bedroom. After dinner time the foul odor can linger in my home all night. My child has asthma. So Fragrances, air fresheners, plug ins, diffusers ….are a no. I have been opening all the windows and running the ceiling fan which is a great solution. It works. However I can’t use that same solution for winter. I hung 2 bags in the ceiling on the AC vent & within 1 hour I could tell the odor was leaving. This gives me hope about maintaining a fresh smelling home.

Using these for covering litter box smell. Doesn't really work. May work for other things.
