Share This Guide

I know there have been times when you walked into a room and were hit with a wall of musty, stale air. Or perhaps your new apartment smells a bit funky, or have a closet with that weird Uncle Dan smell. I’m sure this is why you are researching bamboo charcoal bags.

Naturally, the next question you ask yourself is, “Do bamboo charcoal air purifying bags really work, or are they just another gimmicky air freshener?” Well, I’ve done the research, and I’m here to give you the scoop on how these little bags work and whether they’re worth the investment.

From eliminating bad odors to reducing indoor air pollutants, bamboo charcoal air purifying bags are all the rage right now. But how exactly do they work? Are they really eco-friendly? And most importantly, do they actually deliver on their promises? I’ve got all the answers you need, so buckle up and get ready to learn everything you’ve ever wanted to know about bamboo charcoal air-purifying bags!

Bamboo charcoal packaged in linen bags is an air purifier that removes allergens such as mold, bacteria, bad odors, and even excess humidity from indoor air. The bags can last up to 2 years, so they’re a cost-effective natural alternative to air purifiers.

If you see the thousands of Amazon reviews on activated bamboo charcoal bags, you’ll quickly notice how effective these are at freshening the air in a room. I have reviewed a few of the bags I’ve used (or tested) below, so be sure to check them out. But first… a little science 🙂

How Does A Bamboo Charcoal Purifier Work?

How does a bamboo charcoal purifier work

Key Takeaways:

  • Bamboo charcoal air purifiers work through adsorption, where indoor air pollutants and odors are attracted to and trapped on the surface of the porous bamboo charcoal.
  • The huge surface area of bamboo charcoal, with millions of tiny holes, makes it an effective material for adsorbing pollutants and odors.
  • Over time, bamboo charcoal bags become saturated and need to be recharged or replaced to continue working effectively.
  • Recharging typically involves placing the bags in direct sunlight for a few hours to release the trapped pollutants and odors.
  • Bamboo charcoal air purifiers are an eco-friendly and effective way to remove indoor air pollutants and odors from your living space.

The porosity of bamboo charcoal creates a surface area that traps pollutant particles as air flows over it. This is why there are even charcoal water purifiers that work well.

Bamboo charcoal removes toxins and pollutants from the air through a process called adsorption. Adsorption is when a solid absorbs liquids, gas, or solute in a condensed layer, such as everyday household pollutants such as mold and unpleasant odors.

Bamboo charcoal bags work to purify the air differently from purifiers that absorb impurities. Charcoal traps pollutants on the surface as dirty air passes over it, allowing clean air to circulate in the house.

Note: A single gram of activated carbon has approximately 10,000 square feet of internal surface area. That’s why it is used in some air purification filters and chemical air purifiers.

Therefore, a 1lb bag of activated charcoal has a surface area of about 125 acres, making it a massive air purifier capable of adsorbing many impurities from indoor air.

Bamboo charcoal is preferred for making air purifier bags because it has an even more significant surface area per gram when activated. It is more potent than regular charcoal at cleaning the air, removing excess humidity in the house, and getting rid of airborne toxins.

Benefits of Bamboo Charcoal Bags

Here are a few points on what really makes bamboo charcoal effective as a natural air purifier:

  • Activated bamboo charcoal has 10 times the surface area of regular charcoal.
  • It is 4 times more capacity to absorb odors, allergens, and other impurities
  • The structure of bamboo charcoal is highly porous and can absorb many types of toxins, including ammonia and formaldehyde.

Best Bamboo Charcoal Air Purifier Bags (Reviews)

Air purifiers are great. Brands like Levoit have amazing reviews for their innovative air purification products. Still, instead of using one of their models, you can find a cheaper and more natural alternative, inactivated bamboo charcoal air purifying bags.

I tested some of these bags for different tasks – removing shoe odor, dehumidifying a room, clearing dust, and getting rid of mold spores, and cigarette smoke odors. Here are the best bamboo charcoal bags for air purification and dehumidification from our testing.

AirJoi Air Purifying Bag Review

Ok, so the king of the activated charcoal bag game is Airjoi, right? At least, according to the marketing and the website from AirJoi, it seems to be. So with all the hype around the AirJoi brand, many people ask, “So is AirJoi worth it?”

So after getting a 3-pack a few weeks ago, I have noticed a significant difference in the kitten room we have set up in our spare bedroom to foster a new litter of kittens. As cute as these things are, they can get smelly. So the test was on to see if using 3 AirJoi activated charcoal bags was up to snuff.

As with all activated charcoal bags, you need to ‘activate’ the charcoal by letting the bags sit in the sun for one hour. You won’t notice any smell difference if you don’t do this. These bags sometimes get a bad rap from individual reviewers online.

So with the bags activated, the test was on in the kitten room. After day two, there was a noticeable difference around the room, where the air smelled cleaner than before bringing the bags in. There was still a musty ‘dirty cat litter box smell, but it was faint and did not hit you in the face like before.

So I ‘activated’ the charcoal again in the sun for another hour after the 2nd day and then did an official smell test after day 4. I am unsure if I am just getting used to the kitten room smell after this many days, but the room smelled fresh enough for being a kitten room.

Bamboo Charcoal Vs. Regular Charcoal Bags

Charcoal bags are typically made from activated charcoal, produced by heating carbon-rich materials like wood, coal, or coconut shells. On the other hand, bamboo charcoal bags are made from bamboo charcoal produced by heating bamboo at high temperatures.

The main difference between the two air purifying bags is the source of charcoal. Bamboo charcoal is believed to be more eco-friendly than activated charcoal, as bamboo is a fast-growing and renewable resource. Bamboo charcoal also has a more porous surface area than activated charcoal, allowing it to absorb more pollutants and odors.

Another difference is the way they are produced. Activated charcoal is typically made using a chemical activation process, while bamboo charcoal is produced through a physical process that involves heating bamboo at high temperatures.

In terms of effectiveness, both types of air purifying bags can effectively remove indoor pollutants and odors. However, some people prefer bamboo charcoal bags because they are more environmentally friendly and may have a longer lifespan than activated charcoal bags.

Here are the differences between regular charcoal and bamboo charcoal in purifying air:

May have a shorter lifespan compared to bamboo charcoal bagsMay have a longer lifespan compared to activated charcoal bags

How long do bamboo charcoal bags last?

A bamboo charcoal air purifying bag can last up to 2 years when being used to clean indoor air. After that, you can recharge the bag by placing it outside under direct sunlight for the toxins and odors to break down and dissipate into the atmosphere.

In an average household without excessive pollutants like those you’d find near a construction site, bamboo charcoal air purifiers should remain effective at cleaning the air for at least 2 years or slightly longer.

However, suppose you start experiencing impurities such as allergens (e.g., mold spores in the air). In that case, you might want to replace the air purifier bag with one from the list of the best bamboo charcoal air purifier bags I tested and reviewed above.

Do bamboo charcoal bags remove dust?

Activated bamboo charcoal bags attract and remove dust from the air because they have a lot of tiny pores that create a large surface area for charged dust particles to stick onto.

If you’re cleaning your house after a DIY remodel, placing these charcoal air-purifying bags in various corners would be a great idea to remove drywall dust from indoor air.

In some air purifiers, the filters are laced with activated charcoal to make them more effective at trapping and filtering out dust particles from the air that passes through them.

However, not all air purifiers contain activated charcoal in their filters. For example, air purifiers that have washable filters do not contain activated charcoal because washing can damage the carbon’s potency and reduce the air purification ability.


Are Bamboo Charcoal Air Purifying Bags safe for pets and children?

Bamboo charcoal air purifying bags are safe for pets and children to be around. Unlike traditional air fresheners, they do not contain harsh chemicals or synthetic fragrances that can be harmful if ingested or inhaled. However, it’s important to keep the bags out of reach of children and pets to prevent accidental ingestion.

Can Bamboo Charcoal Air Purifying Bags be reused?

Yes, bamboo charcoal air purifying bags can be reused. To recharge the bags, place them in direct sunlight for a few hours every month. This will help to reactivate the charcoal and remove any trapped particles.

Can Bamboo Charcoal Air Purifying Bags be recycled?

Bamboo charcoal air purifying bags can be recycled once they have reached the end of their useful life. The bags are made from natural bamboo charcoal, which is a biodegradable material that will break down over time.

How long does it take for bamboo charcoal air purifying bags to start working?

Bamboo charcoal air purifying bags typically start working as soon as you place them in your living space. However, the length of time it takes to see results may vary depending on the size of the space, the level of pollutants or odors, and the number of bags used. It’s important to note that bamboo charcoal air purifying bags work through adsorption, so it may take some time for them to trap and remove all of the indoor pollutants and odors.

Can bamboo charcoal air purifying bags be used in a car?

Yes, bamboo charcoal air purifying bags can be used in a car to help remove odors and pollutants. To use bamboo charcoal air purifying bags in a car, simply place one or more bags in the car, ideally in areas with good air circulation such as on the dashboard, backseat, or near the air conditioning vents.

Can bamboo charcoal air purifying bags be used to remove cigarette smoke smell?

Yes, bamboo charcoal air purifying bags can be effective in removing cigarette smoke smell from indoor spaces. The porous surface of bamboo charcoal can adsorb the odor-causing particles in the air, leaving your living space smelling fresher and cleaner.

Are bamboo charcoal air-purifying bags safe for pets?

Bamboo charcoal air purifying bags are generally considered safe for pets, as they are a natural and non-toxic air purification solution. However, it’s important to remember that pets may be attracted to the bags and may try to chew or eat them, which could pose a choking hazard. To prevent this, place the bags in areas out of reach of pets.

Do bamboo charcoal air purifying bags work for allergies?

While bamboo charcoal air purifying bags can help reduce indoor air pollutants, they may not work for all allergies. A variety of triggers, such as dust mites, pet dander, pollen, or mold spores can cause allergies. Bamboo charcoal bags can help remove some of these triggers from the air, but they may not be effective for all types of allergens.
