Low Resistance G3 G4 Activated Carbon Filter (35Pa) for HVAC Odor Control
Improving indoor air quality (IAQ) without increasing energy costs is the primary goal for modern facility managers. Our G3 G4 Activated Carbon Filter is designed for low resistance (35Pa) and high-volume airflow, making it the perfect upgrade for any central air conditioning system. This G3 G4 Activated Carbon Filter provides efficient odor control filtration while protecting downstream components from dust accumulation.
Product Key Features
Ultra-Low Resistance (35Pa): This G3 G4 Activated Carbon Filter minimizes HVAC energy consumption while maximizing airflow.
Massive Airflow Capacity: Rated for up to 4000 $m^3/h$, ideal for large-scale central HVAC systems.
Odor Removal Specialist: Specifically targets tobacco smoke, food court smells, and common indoor VOCs.

Material & Craftsmanship
Pleated G3 G4 Activated Carbon Filter: 3mm to 5mm carbon cotton for optimal dust holding and low pressure drop.
Bag/Pocket Carbon Filter: Designed for maximum surface area in high-capacity HVAC units.
Aluminum Frame Carbon Filter: Lightweight and anti-corrosive, perfect for easy installation and maintenance.
Applications
Commercial Office Buildings & Skyscrapers: Removes indoor “stuffiness,” ozone from office printers, and tobacco smoke, significantly enhancing Indoor Air Quality (IAQ) and employee productivity with a low resistance carbon filter.
Luxury Hotels & Shopping Malls: Neutralizes complex public space odors—from perfumes and cleaning agents to heavy food court smells—ensuring a fresh, premium atmosphere that enhances the guest experience.
Healthcare Facilities & Clinics: Provides essential secondary filtration to capture medical disinfectant smells and organic chemical vapors, creating a neutral and comforting environment for patients and medical staff.
Education & Public Institutions: Ideal for schools and libraries to manage VOCs from building materials and high-traffic humidity while maintaining high-volume airflow through the ventilation system.
Commercial Kitchen Exhaust: Acts as a secondary scrubber to strip grease-laden odors and smoke residues from kitchen air before it is recirculated or discharged near pedestrian walkways.

Frequently Asked Questions
Q:Will the G3 G4 Activated Carbon Filter reduce my HVAC system’s airflow?
No. Our filters are designed for ultra-low resistance (approx. 35Pa), ensuring they provide maximum odor control without restricting the high-volume airflow of your central air conditioning system.
Q:Can this replace my existing G4 pre-filter directly?
Yes. Since it meets G3 and G4 filtration class standards, it serves as a direct upgrade that provides both physical dust capture and chemical odor adsorption in one unit.
Q:Is the ‘Bag/Pocket’ design better for large buildings?
For massive rooftop AHUs, the bag-style G3 G4 Activated Carbon Filter is preferred because it offers a larger surface area, resulting in longer life and better performance under high velocities.
Q:Are these filters fire-resistant for safety compliance?
Yes, our activated carbon cotton media is treated with fire-retardant additives to meet standard commercial safety regulations for HVAC air filtration.
Q:How do I order a custom size G3 G4 Activated Carbon Filter?
We specialize in B2B customization. Simply provide your dimensions, and our 20-year production team will manufacture custom size aluminum frame filters to fit your specific housing perfectly.
