【What】is OZCHIN's Effective Odor Control Formula

OZCHIN's odor control bags feature a special activated carbon formula of 200g/m², which maximizes odor capture through high-capacity physical adsorption that imitators simply can't match. Activated Carbon Fiber, abbreviated as ACF below, is the third generation of novel porous adsorption materials developed after granular activated carbon. It features a large specific surface area, abundant micropores, and strong adsorption and desorption capabilities. It is hailed as one of the most advanced environmentally friendly materials of the 21st century and is known as "black gold."

【Why】does Activated Carbon Fiber have its unique adsorption properties?

The extraordinary function of ACF lies in its surface being covered with micropores of 0.8-2 nanometers. It has the function of filtering air, and uses "van der Waals forces" to adsorb odor molecules (such as formaldehyde and benzene with molecular diameters of 0.5-0.58 nm) into the micropores, thereby purifying the air. ACF has the characteristics of fast adsorption and desorption. Civil products made of ACF, after reaching adsorption saturation, the material's efficiency can be restored by exposure to sunlight and ventilation, which helps desorb volatile substances. It can be used repeatedly for thousands of times.

【How】 does it capture odors?

A 2021 study (Source: https://pubs.acs.org/doi/10.1021/acsomega.1c04196) found that the smell of the Green Leaves is actually caused by a sulfur compound called 3-methyl-2-butene-1-thiol (VSC3). Its structure is very similar to the chemicals in skunk secretions, and it can be smelled even at extremely low concentrations. The physical size of these odor molecules is extremely small, usually between 0.5 and 1 nanometer (nm). This is why simply wrapping Green Leaves in a plastic bag makes it difficult to completely isolate its smell—the molecules permeate through the micropores of the polymer. When odor molecules (such as terpenes or sulfides) float into the micropores of these ACF, they generate van der Waals forces with the carbon atoms. Because this force is very effective in tiny spaces, the molecules are firmly "adsorbed" onto the surface of the carbon, thus being effectively trapped and removed from the air.

【Which】will be better among ACF, Granular Activated Carbon, and Bamboo/Wood Charcoal?

ACF is prepared from organic fibers such as viscose fibers, phenolic fibers, polypropylene fibers, and pitch fibers through high-temperature carbonization and activation under an inert gas atmosphere.
Unlike high-performance activated carbons, standard bamboo and wood charcoal often lack a specialized activation process (such as steam or chemical activation). This results in a poorly developed micropore structure and a much smaller specific surface area. Consequently, they reach adsorption saturation in a very short time and lose their adsorption function.
Furthermore, once saturated, these basic charcoals cannot be easily desorbed in a household setting. If not replaced promptly, the trapped pollutants remain in the activated carbon, they can cause secondary pollution in the living space. Therefore, bamboo charcoal and wood charcoal are not ideal adsorbent materials.

【When】is maintenance or replacement needed?

It is recommended to expose the inner liner to sunlight for 2-3 hours every two weeks to trigger desorption and regeneration to maintain optimal performance. Just simply unzip the bag and expose the inside to sunlight. When a noticeable odor persists even after sun exposure, it indicates that the adsorption sites are completely saturated, and replacement is recommended.

Odor Control FAQ

Does it really block smell and work against police dogs?

Odor control? Definitely yes. OZCHIN uses 200g/m² Activated Carbon Fiber (ACF) to physically trap odor molecules instead of just masking them.

Police dogs? There is no guarantee. They are mainly aimed at human olfactory senses and ordinary environments. Against professionally trained police dogs, any civilian-grade product carries risk.

Is it safe?

Yes. Activated carbon fiber is non-toxic, chemical-free, and widely used in air purification.

What makes OZCHIN different?

High-density Activated Carbon Fiber
Optimized micropore structure
Strong physical adsorption

Imitations use lower-grade carbon or coatings that saturate quickly.

How long does odor control last? How do I refresh the smell proof liner?

With normal use, it lasts years. Performance depends on odor intensity and usage frequency.

Expose the inner liner to sunlight for 2–3 hours every 2 weeks to regenerate adsorption.

If odor remains after sun exposure, the liner is fully saturated and should be replaced.

Use it daily! Love it!

Amazing customer service to help figure out a shipping issue that was my fault. That on top of a great product with top notch quality. I'll definitely be buying from them again!!!

Love this bag keeps my products safe and out of reach, makes my friends jealous, offers reconfigurable storage and ocd peace of mind. Keep creating these.

What smell??

I like to be discreet with my extracurricular activities and this little bag allows me to do just that!! There are plenty of pockets and compartments to store some of everything!! And once closed you can't smell A THING!! The fact that it locks makes it even better because - DISCRETION!! The additional mylar bags, storage container and grinder are a great bonus and are of great quality AND BEAUTIFUL too - if such things can even be beautiful!! I would definitely recommend this bag to anyone who doesn't want anyone else's NOSE in their business!! Great quality for the price!!

Buy it! Best value

I can confidently say this is one of my best purchases. Very durable bag, I've had it for about 2-3 months now and use it daily, 9/10 smell proof, only way I've found that the smell can leak out is when the zippers are locked, there is a very small opening that you can smell through but only if you're really trying. I take this bag everywhere and no body suspects a thing, definitely recommend it. A little sad that they updated the logo on the front, when I ordered the bag they still had the old logo in the pictures but I received the current new logo which is plane in my opinion.
