Honeycomb activated carbon is a highly efficient adsorption material specifically designed for treating large-volume, low-concentration waste gases. Produced via an extrusion molding process, it takes the form of a solid block containing thousands of parallel, straight-through channels that create a regular, honeycomb-like structure. This unique configuration combines the powerful adsorption capabilities of activated carbon with extremely low airflow resistance. Within the ductwork of a Fresh Air System, honeycomb activated carbon plays a pivotal role akin to a "pulmonary filter." Its primary function is to remove odors, harmful gases (such as SO₂ and NOx), and certain volatile organic compounds (VOCs) from incoming outdoor air, all while ensuring the unimpeded flow of air volume. Given that fresh air systems are typically installed within suspended ceilings and require continuous 24-hour operation, there are exceptionally stringent requirements regarding the airflow resistance (pressure drop) and safety of the activated carbon utilized.

Q: How do I select the appropriate specifications for honeycomb activated carbon used in fresh air filtration systems?
A: The key to selecting honeycomb activated carbon specifications lies in balancing adsorption efficiency with airflow resistance (or anti-clogging capability). Simply put, the pore size should be determined based on the molecular size of the pollutants present in the ductwork and the dust concentration levels.
Q: How often should honeycomb activated carbon used for air purification be replaced?
A: Recommended replacement cycle: 6–12 months. Basis for judgment: Fresh air systems typically do not provide obvious "odor" cues (since the air is constantly being exchanged). We recommend performing a replacement once a year during a seasonal transition (e.g., just before the onset of the winter smog season), taking local air quality conditions into account.
Q: Do you support the customization of special specifications?
A: Yes, we do. We can customize honeycomb dimensions, pore sizes, and packaging specifications, and we provide third-party inspection reports upon request.
We offer free sample testing and technical guidance support. For bulk purchases, we provide customized solutions and preferential pricing. We guarantee free returns or exchanges for any quality-related issues that arise during the warranty period.
Certifications: ISO 9001 Quality Management Certification; compliant with safety requirements for air purification applications.
For fresh air system ductwork applications, we recommend selecting honeycomb activated carbon with a density of 100–150 CPSI (Cells Per Square Inch), a coal-based substrate, and flame-retardant properties.
100 CPSI (Pore size: approx. 4 mm): Offers minimal airflow resistance; suitable for scenarios involving high airflow volumes or poor outdoor air quality (slightly higher dust concentrations), as it is less prone to clogging.
150 CPSI (Pore size: approx. 3 mm): Features a larger specific surface area and higher adsorption efficiency; suitable for systems with stringent air quality requirements and effective pre-filtration stages.
If the installation site is located near a chemical plant or within a newly renovated building, we recommend upgrading to impregnated (chemically modified) honeycomb carbon to enhance the removal capability for specific chemical gases.
During installation, there must be no gaps between the honeycomb carbon block and its mounting frame (any gaps should be less than 3 mm). Otherwise, the airflow will "take a shortcut" (short-circuiting), resulting in a significant portion of the air entering the indoor space without undergoing filtration.
Since fresh air carbon filters are typically installed in close proximity to the system motor or within confined ceiling spaces, fire safety performance is of paramount importance. Professional Support: With over 25 years of experience in the R&D and production of activated carbon for VOC waste gas treatment, we provide personalized, one-on-one guidance on product selection.
