Description
Activated Carbon & High-Efficiency HVAC Filtration
V-Bank Carbon-Blend Air Filter
AccuraFil V-Bank Carbon-Blend Air Filters combine particulate filtration and molecular gas-phase filtration in a single high-efficiency HVAC filter. The V-bank configuration provides extended media surface area while the carbon-blend media is designed to address a broad range of gaseous contaminants.
Available in MERV 10 and MERV 13 configurations per ASHRAE 52.2, the filter uses a 50/50 blend of activated carbon and potassium permanganate (KMnO₄) micro-granulate embedded in dual-layer synthetic media. The corrosion-resistant ABS plastic frame and 20 mm peripheral header provide a durable configuration for compatible commercial, industrial, healthcare, pharmaceutical, transportation, data center, and other HVAC applications requiring both particulate and molecular contaminant control.

50/50 Activated Carbon & KMnO₄ Molecular Filtration
The V-Bank Carbon-Blend Filter uses a 50/50 blend of activated carbon and potassium permanganate (KMnO₄) micro-granulate embedded within dual-layer synthetic media. The carbon/KMnO₄ blend provides the molecular filtration component while the MERV-rated synthetic media provides particulate filtration.
Activated carbon is used for adsorption of gaseous contaminants, while the potassium permanganate component provides chemical treatment for selected molecular pollutants. Combining the two media in one filter provides a broad-spectrum approach to particulate and gaseous contaminant control.
50/50 Carbon + KMnO₄ Blend
The carbon-blend media contains 60% CTC activated carbon/KMnO₄ blend micro-granules designed to provide a large active surface area for molecular filtration and adsorption.
Targeted Gaseous Contaminants
The carbon/KMnO₄ blend is designed for molecular filtration of gaseous contaminants commonly encountered in commercial, industrial, transportation-influenced, data center, and specialized HVAC environments.

Other Gaseous Compounds
V-Bank Design for Efficient HVAC Airflow
The V-bank configuration arranges the filtration media into multiple angled sections, increasing effective media surface area within the available filter footprint. The mini-pleated V-bank design supports efficient airflow while providing media volume for particulate and molecular filtration.
The 12-inch filter depth provides substantial media volume for applications requiring combined particulate filtration and gas-phase contaminant control.
Choosing the Right MERV Rating
Select the appropriate particulate filtration efficiency based on facility requirements, indoor air quality objectives, system design, airflow, and allowable pressure drop.
MERV 10
Suitable for general commercial, transportation, and light industrial HVAC applications requiring particulate filtration together with molecular contaminant control.
MERV 13
Higher-efficiency particulate filtration for healthcare, commercial, pharmaceutical, laboratory, and other applications where increased particulate control is required.
ABS Frame & 20 mm Header Construction
The V-Bank Carbon-Blend Filter uses a corrosion-resistant ABS plastic frame rather than a conventional metal frame. The non-metal construction is intended for applications where resistance to corrosion is an important consideration.
A 20 mm peripheral header provides the mounting interface for compatible HVAC filter racks and V-bank housings.
Always verify the existing filter housing dimensions, header configuration, sealing arrangement, and installation requirements before ordering a replacement filter.

Hospitals & Healthcare
Combined particulate and molecular filtration can help address mixed airborne contaminant conditions in healthcare HVAC environments.
Pharmaceutical Manufacturing
Higher-efficiency MERV configurations provide particulate filtration while the carbon-blend media addresses selected gaseous contaminants in compatible pharmaceutical and controlled environments.
Data Centers
Combined particulate and molecular filtration can help address gaseous contaminants that may contribute to corrosion concerns for sensitive electronic equipment.
Transportation Hubs
The carbon/KMnO₄ blend is designed to target gaseous pollutants associated with vehicle exhaust and outdoor-air intake conditions.
Wastewater Treatment

How to Select the Right V-Bank Carbon-Blend Filter
-
Identify the Target Contaminants
Determine whether the application requires particulate filtration, molecular filtration, or both. Target gaseous contaminants may include VOCs, vehicle exhaust, SOx, NOx, ammonia, ozone, and other gaseous compounds.
-
Select the Required MERV Rating
Choose MERV 10 for general commercial, transportation, and light industrial applications. Choose MERV 13 where higher particulate filtration efficiency is required, including compatible healthcare and pharmaceutical applications.
-
Confirm Housing Compatibility
Verify that the AHU or filter housing accepts a 12-inch-deep V-bank filter with a 20 mm peripheral header. Confirm actual filter dimensions and the housing configuration before ordering.
-
Verify Temperature & Pressure Drop
Confirm that operating temperature does not exceed 131°F (55°C) and that the HVAC system can accommodate the recommended final pressure drop of 1.50" w.g..
V-Bank Carbon-Blend vs. Separate Carbon & Particulate Filters
Conventional HVAC systems may use a separate particulate filter and a dedicated activated carbon or gas-phase filtration stage. The AccuraFil V-Bank Carbon-Blend Filter combines these functions in one filter configuration, providing a compact approach for applications requiring both particulate and molecular contaminant control.
The V-bank geometry provides extended media surface area while the carbon/KMnO₄ blend provides molecular filtration. The appropriate configuration depends on contaminant concentration, required MERV efficiency, airflow, available installation depth, and the HVAC system's pressure-drop limitations.
Product Selection & Procurement
Before ordering a replacement V-Bank Carbon-Blend Filter, verify the actual filter dimensions, 12-inch depth, 20 mm header configuration, MERV rating, airflow requirements, pressure-drop limits, and compatibility with the existing HVAC housing or filter rack.
For molecular filtration applications, identify the target gaseous contaminants and evaluate whether the carbon/KMnO₄ media is appropriate for the specific contaminant conditions, concentration, airflow, and operating environment.
AccuraFil supplies commercial and industrial HVAC filtration products for facility managers, HVAC contractors, mechanical engineers, healthcare organizations, pharmaceutical facilities, data center operators, IAQ professionals, and procurement teams.
Frequently Asked Questions
What is a V-Bank Carbon-Blend Filter?
A V-Bank Carbon-Blend Filter combines particulate filtration with molecular gas-phase filtration in a V-shaped filter configuration. AccuraFil's model uses MERV-rated synthetic media together with a 50/50 blend of activated carbon and KMnO₄ micro-granulate.
What contaminants does the Carbon-Blend Filter target?
The filter removes volatile organic compounds (VOCs), vehicle exhaust compounds, sulfur oxides (SOx), nitrogen oxides (NOx), ammonia (NH3), ozone (O3), and other gaseous pollutants. Activated carbon handles organic gases and VOCs through adsorption; KMnO4 (potassium permanganate) handles inorganic gases including SOx, NOx, and ammonia through chemical oxidation. Particulate filtration is simultaneously provided at MERV 10 or MERV 13 efficiency.
What is the difference between activated carbon and KMnO₄?
Activated carbon removes gaseous contaminants through physical adsorption — capturing organic molecules and VOCs in its porous surface structure. KMnO4 (potassium permanganate) removes contaminants through chemical oxidation — reacting with and neutralizing inorganic gases such as SOx, NOx, ammonia, and ozone that activated carbon alone cannot effectively adsorb. The 50/50 blend provides broad-spectrum molecular filtration covering both organic and inorganic gaseous contaminants in a single filter stage.
