When to Use a 46mm Activated Carbon Filter

Comparison of 46mm Activated Carbon Filters vs. Other Thicknesses: When Should You Choose the Thicker Type? 

Detailed Analysis of Activated Carbon Filter Thickness and Choosing the Right Type for Different Applications 

Introduction to Pleated Activated Carbon Filters 

Pleated activated carbon filters are an effective solution for eliminating and preventing odors and smoke in the air, commonly used in HVAC systems. These filters are composed of three main parts: the activated carbon layer, a supporting layer, and a frame. The thickness of the filter is a crucial factor that affects filtration performance and its suitability for various applications. 

Besides choosing based on exhaust treatment needs, factors such as HVAC usage frequency, air pollution levels at the installation site, and filter longevity requirements should also be considered. If your system operates continuously in environments with heavy dust, chemical odors, or volatile organic compounds, using a thicker filter can help reduce replacement frequency while maintaining stable filtration performance over time. Additionally, for facilities requiring strict air quality control, such as hospitals, pharmaceutical plants, or laboratories, prioritizing thicker filters offers superior protection, contributing to better health and safety for users. 

Common Thicknesses of Activated Carbon Filters 

Currently, the two most common thicknesses for activated carbon filters are 46mm and 96mm. Filter sizes are diverse and can be customized to suit specific needs. The thickness directly impacts odor absorption capacity, airflow rate, and product durability. 

Technical Specifications Comparison: 46mm vs. 96mm Filters 

Product Code	External Size (W × H × D, mm)	Thickness (mm)	Initial Resistance (Pa)	Rated Airflow (m³/h)
DC-CA-012	495 × 495 × 46	46	70	1500
DC-CA-022	495 × 595 × 46	46	70	1800
DC-CA-062	495 × 495 × 96	96	45	1500
DC-CA-084	495 × 595 × 96	96	45	3000

The 46mm thickness is popular, easy to install, reasonably priced, and suitable for residential HVAC systems or small industrial setups. The 96mm type is thicker and commonly used in environments demanding stronger odor, smoke, and chemical absorption. 

Performance Comparison: 46mm vs. Thicker Filters 

• Odor and Chemical Absorption: Thicker filters (96mm) contain more activated carbon material, allowing longer contact time between air and carbon, resulting in more effective removal of odors, smoke, and chemicals. Meanwhile, the 46mm variant is suitable for standard filtration needs where high pollution levels are not present. 
• Airflow and Resistance: The 96mm type has a lower initial resistance (45Pa) compared to the 46mm type (70Pa), enabling easier airflow in larger systems. However, its larger size may require more installation space. 
• Longevity and Replacement: Thicker filters generally last longer due to having more carbon material and require less frequent replacement. Especially when using metal frames (aluminum or galvanized steel), the carbon inside can be easily replaced, saving on long-term costs. 
• Investment Cost: The 46mm type is more affordable, ideal for smaller systems without high filtration demands. The 96mm filter is more expensive but delivers superior filtration efficiency, making it suitable for industrial environments, clean rooms, or areas with high air pollution. 

When Should You Use Thicker Activated Carbon Filters? 

Choose 96mm or thicker activated carbon filters in the following cases: 

1. Areas with high levels of air pollution, odors, or chemicals, such as factories, laboratories, or production zones. 
2. Large HVAC systems requiring high airflow and maximum filtration efficiency. 
3. Environments where strict air quality standards must be maintained, such as clean rooms, hospitals, or data centers. 
4. When you want to reduce filter replacement frequency and save on long-term operational costs. 

On the other hand, for basic filtration needs, limited installation space, or tight budgets, the 46mm filter is the optimal choice, offering effective filtration at a lower cost. 

Conclusion 

The choice of activated carbon filter thickness depends on your specific application, installation environment, and air quality requirements. The 46mm filter is suited to standard needs and cost savings, while thicker types like the 96mm provide better performance for highly polluted areas, demanding filtration, and longer lifespan. As the saying goes, “Measure your needs and choose wisely,” so consider your actual requirements carefully to select the most suitable product for your system.
