What Do the Bags Do? If you have been in a room or vehicle that has a bad odor, then you would agree that it is not an enjoyable experience. You might also think that the air isn’t safe to breathe in. People typically assume that the air is filthy whenever they smell something unpleasant.

Keep in mind that these bags do not work like air freshener aerosol sprays as the bags are odorless. If you do smell something after you have placed the bag, you’re probably smelling fresh air!

How Does Bamboo Charcoal Air Purifier Bags Work?

These bags only contain one ingredient – bamboo charcoal. The charcoal contains microscopic pores that and soaks up the smallest of particles that are noticeable around you. These tiny pores also destroy bacteria that cause bad odors, leaving behind pure fresh air.

The other benefits of bamboo charcoal other than deodorizing are:

  • Absorbing moisture
  • Removing formaldehyde
  • Removing undesirable pollutants and contaminations from the air

The bags are manufactured from linen, an exceptionally breathable type of material. The air goes through the material and then passes through the bamboo charcoal which is placed inside.

What sized room the charcoal can “clean” depends on how large the room is as well as the amount and quality of the bags you are using. A 200 g bag is sufficient for about 90 square feet – suitable for a smaller room, washroom, kitchen, storeroom, or your vehicle.

It can take a few days for the space to be completely deodorized.

Once you have finished the process, you could always use the bag as fertilizer for your plants in the garden.

Advantages of an Air Purifying Bag

Below are some reasons why you should consider one of these bags.

Eliminates Bacteria. Bacteria are all around us but that does not mean you should be careless about it. If you or your loved ones have vulnerable immune systems, it would be a good reason to use these bags to take care of bacteria. Using these bags also curbs the possibility of bacteria spreading.

Non-toxic and Chemical-free. Aerosol-based air fresheners contain harmful chemicals that both toxic and expensive. While these chemicals won’t kill you, they are not beneficial for you either. Air purifying bags, on the other hand, use natural ingredients and are completely harmless.

What is Bamboo Charcoal?

If you have not heard of bamboo charcoal, don’t feel bad since it’s not well-known. Don’t stress, as you’ll find out more as you read along.

So what is it? It is also called activated charcoal and is a common method of filtration in Asia. It is made from bamboo residue that is tightly packed and carbonated. It is then exposed to high temperatures that eventually produce charcoal. At this point, however, it is not “activated” charcoal yet.

The activation only occurs once it has been exposed to extreme temperatures and oxygen is added, which causes the charcoal to activate. Once this step has been completed, it becomes activated bamboo charcoal.

Advantages of Bamboo Charcoal. Still not sold on the idea? Below are three of the best advantages of using activated bamboo charcoal.

It’s Sustainable

As mentioned before, bamboo charcoal is produced using the remains of bamboo. Although it contains a lot of carbon like coal, bamboo charcoal is a natural product and therefore does not affect the climate in any way. Moreover, bamboo plants grow significantly faster than trees and you will have enough stock to meet increasing demand.

Do you realize that you only need a couple of grams of bamboo charcoal to purify the air in a room? If you used aerosols, you have to be much more liberal with it.

It is Odorless. Don’t be fooled if you can’t smell any scents since that is one of the advantages of using it. Why? That’s because bamboo charcoal doesn’t mask odors by scenting the air and also doesn’t rely on synthetic substances to produce fragrances. It’s completely natural and therefore non-toxic.

It Long-lasting. To add to the list of advantages, it has an incredibly long lifespan. A bag can remain effective for as long as two years if properly taken care of. Yes, that’s right, it can provide you with two years of service before you have to replace it. This would save you some cash as you don’t have to replace them regularly.

Instructions to Use Bamboo Charcoal Air Purifying Bags

So how precisely do you utilize one of these bags? All you need to do is place the bag in the sun for about an hour to activate the charcoal. The ultraviolet rays activate the filtering properties of charcoal. If you don’t have a lot of sunlight, then just leave it out for an hour or longer.

Once it has been exposed to the sun, you can use the bag anywhere you like. You can even use it inside shoes and duffel bags to eliminate odors. To maintain its effectiveness, place it under the sun once a month to recharge and activate the charcoal. There is no need to heat it or wash it.

You need to know that the charcoal doesn’t absorb the air particles, but adsorbs them.

Adsorption is the process where chemicals are drawn in and adheres to the charcoal, which makes it weigh more. Bamboo charcoal is incredibly permeable, which means that a lot of synthetic substances and be adsorbed into those little pores. If you need proof, you’ll notice that the bag gets heavier with use.

Does it Actually Work?

You now understand what it is and how it goes about its business, but is it effective? If you want quantifiable information and verification that it is working, you’ll be disillusioned because the bag doesn’t have a sensor that discloses to you the amount of air it has been able to clean. Regardless, there are different things you can monitor to know whether it’s working effectively or not.

To start, you’ll notice the smell of the room. While it doesn’t radiate any smell, it will eliminate foul odors in the room or space you placed it in. That alone is proof that it’s functioning properly. If your room used to have some smell to it and now it smells clean and fresh, then it is working.

The Weight of the Bag

Over some time, you’ll notice that the bag gets heavier. That is another clue that it has adsorbed a lot of synthetics and pollutants. If you feel that the bag is getting heavier, you should leave it under the sun for about 60 minutes. The adsorbed substances will then disappear and you can reuse the bag.

If you are still in doubt, you can get hold of a study undertaken by the Nagaoka University of Technology in Japan regarding bamboo charcoal. The study that was undertaken shows that bamboo charcoal is a very effective countermeasure to address unhealthy gasses and toxins found everywhere. It is also able to adsorb formaldehyde and toluene, which are harmful to people.

Bamboo Charcoal Is Not a Scam

Charcoal is normally produced from different types of wood. However, bamboo charcoal is better at absorbing moisture and odors. Other materials that contain activated charcoal with similar properties are coconut husks, peat, wood, and coal.

Bamboo is multiple times better as it is more porous than other types of charcoal and therefore has better absorption properties. You can feel the bag getting heavier all the time. This is a direct result of the absorption process and is confirmation that it’s purifying the air.

Used gym clothing, household pets, and cooking odors all contribute to the smells you would find at home. While aerosol air fresheners can mask these smells, consider adding a few bamboo charcoal bags to appropriately address the root of these odors.

Charcoal encased in a breathable material that is distributed around the house will automatically trap bad scents and freshen up the air indoors. A few factors go into choosing these scent eliminators, so utilize this guide to find out why the following items are considered the best bamboo charcoal air purifier sacks you can purchase.

Practical versus Decorative

Hidden spots in your home that you can’t see are often the places where terrible odors stem from. For these areas, functional reasoning usually wins since there’s very little to decide if you were to place a bag near a trash bin. You can even find bags that come with hooks or loops that you can use to hang them somewhere.

Most bags are plain in appearance, but you can also find some with attractive designs that might brighten up a room. They are often available in different shapes and sizes too.


Size is relative to the bag’s purifying effectiveness – bigger bags can clean more air. The bags are available in many sizes, ranging from 50 grams to over a kilogram.

Other Natural Ways To Purify The Air At Home

Salt Lamps. Himalayan salt lamps are another way to go about it. This pink salt stone is mined in the Indo-Gangetic Plain, and when a stone of reasonable size is discovered, it is used to produce a salt lamp.

By hollowing out the stone and placing a bright bulb in it, the warmth that is generated from the bulb releases negatively charged ions into the air, which eliminates and neutralizes pollutants. These lamps are very distinctive as they have a gorgeous pink glow. Users of these lamps also claim that they encourage better sleep quality and promote better health.

Beeswax Candles. As the name suggests, these are candles made from beeswax. What makes them different, however, is they do not release smoke. Normal candles are manufactured from petroleum and will give off chemicals such as benzene, toluene, or smoke while burning.

On the other hand, beeswax candles are known to release negative ions into the air that removes pollutants. Another advantage of beeswax candles is that they burn a lot slower than normal candles, which means they last a lot longer and do not need to be replaced regularly.

Purifying Plants (Peace Lily). Some plants have been created to clean the air effectively by scrubbing carbon dioxide and converting it to oxygen. What people do not realize is that some plants can also ingest pollutants and toxins such as benzene, formaldehyde, trichloroethylene, toluene, xylene, and ammonia.

Research conducted by NASA has found that the best performing plant is the Peace Lily because it requires almost no water or sunlight. Besides being an attractive-looking plant, it is also able to ingest the chemicals mentioned above while producing healthier, cleaner air.


How Is Bamboo Charcoal Made?

How Does It Freshen the Air?

Bamboo charcoal’s odor-eliminating ability is all thanks to its porosity. The bamboo charcoal inside an air purifying bag consists of numerous tiny holes. These holes essentially trap the particles that cause foul odors, which is a process known as adsorption. Over time, the accumulation of particles will cause the air purifying bag to become heavier.

How Do I Know When It’s Time to Replace My Air Purifying Bag?

On-time monthly recharges will keep an air purifying bag like new for years. However, certain VOCs can remain on the bamboo charcoal even after it’s recharged.

These bags can literally be placed anywhere, it does not really matter where. For the most part they have a grommet which you can use to hang it just about anywhere, on drapes, on the wall etc.

2 thoughts on “What are Air Purifying Bags? Does Bamboo Charcoal Work?”

  1. Is there any scientific proof that the bamboo charcoal really has an effect on indoor air quality?

    It feels a bit strange that you easily find everywhere pitched opinions or advertisements that praise the bags but no real information about the effects. How many % of air pollution is diminished and what type of pollution?

    Is there anyone who has used the bags and found real changes in indoor air quality or personally felt relief from typical physical symptoms that occur in bad indoor air quality?

    Do the bags clean VOCs or mold spores or collect dust? What are the real effects?
