If you’re operating a commercial kitchen, your exhaust system likely relies on commercial kitchen filters. Honeycomb filters have become the preferred choice in Australian commercial kitchens due to their efficiency in grease capture, ease of maintenance, and durability. Understanding how honeycomb filters work, their advantages, and best practices for maintenance can help ensure the longevity and effectiveness of your kitchen’s ventilation system.
What Are Honeycomb Filters?
Honeycomb filters are designed with a unique structure that maximises surface area for grease capture. Your traditional honeycomb filter is constructed from aluminium, and features a ‘filter media’, which is 50mm in depth. These filters effectively remove grease particles from the air while maintaining strong airflow. Their honeycomb pattern allows air to flow smoothly while trapping grease within the filter media.
Most honeycomb filters are made from aluminium or stainless steel, offering both durability and ease of cleaning. These materials withstand high temperatures and are constantly used in commercial kitchens, ensuring long-lasting performance.
Unlike mesh filters, which can clog easily, or baffle filters, which may restrict airflow, honeycomb filters balance efficient grease capture and minimal resistance. Their design allows for effective filtration without compromising the kitchen’s ventilation system.
How Do Honeycomb Filters Work?
As grease-laden air passes through the honeycomb structure, the air is split into thousands of small streams. In fact, often as the air passes through the honeycomb filter, it is split into more than 32,000 separate airstreams (per m2 of filter surface area). This process forces grease particles to adhere to the filter surfaces, preventing them from entering the exhaust system.
The honeycomb design captures grease efficiently while maintaining low airflow resistance. This makes it ideal for various cooking environments with moderate to high grease output.
Honeycomb filters significantly reduce the risk of grease fires by capturing grease before it accumulates in the ductwork. Properly maintained filters also contribute to overall kitchen safety and compliance with fire regulations.
7 Advantages of Using Honeycomb Filters
1. High Filtration Efficiency
With their extensive surface area, honeycomb filters efficiently remove grease particles from the exhaust air, creating a cleaner and safer kitchen environment. This reduces the risk of airborne grease accumulation on surfaces, helping maintain hygiene standards.
2. Improved Airflow
Unlike other filter types, honeycomb filters maintain strong airflow, ensuring efficient ventilation without overloading the system. They help maintain comfortable kitchen conditions by allowing steady airflow, reducing excess heat and improving overall air quality.
3. Durability & Longevity
Constructed from robust materials, these filters withstand the high demands of commercial kitchens, providing a long service life with proper care. Stainless steel honeycomb filters, in particular, resist corrosion and wear, making them an ideal long-term investment.
4. Easy Maintenance
Honeycomb filters are fully washable, making them a practical and low-maintenance option. Regular cleaning ensures they remain effective over time. Many kitchens opt for professional kitchen cleaning services to ensure thorough maintenance, preventing grease build-up that can impact performance.

5. Cost-Effective Solution
Their durability and easy maintenance lower long-term operational costs, making them a smart investment for commercial kitchens. Since they do not clog as quickly as mesh filters and require less frequent replacement, businesses save on cleaning time and filter replacement expenses.
6. Environmental Benefits
By capturing grease efficiently, honeycomb filters contribute to improved environmental sustainability. They reduce the risk of grease entering air ducts and being released into the atmosphere, which can contribute to pollution. In addition to that, their long lifespan minimises waste associated with disposable or frequently replaced filters.
7. Compliance with Safety Regulations
Many commercial kitchens are required to meet strict ventilation and fire safety standards. Honeycomb filters help kitchens comply with regulations by reducing fire hazards and improving overall air quality, ensuring safe and efficient operations.
When to Choose Honeycomb Filters: Best Use Cases
- Medium-to-High Grease Cooking Environments: This is ideal for restaurants, cafes, and catering businesses that produce moderate to high grease.
- Balanced Airflow Needs: Suitable for establishments requiring effective grease removal without compromising ventilation performance.
- Cost-Conscious Commercial Kitchens: A great choice for businesses looking to balance affordability and efficiency.
- Low-Maintenance Operations: Preferred by kitchens that prioritise easy cleaning and minimal downtime.
Comparison with Other Filter Types
Honeycomb Filters vs. Baffle Filters
Baffle filters are highly regarded for fire safety compliance but can restrict airflow more than honeycomb filters. Honeycomb filters provide easier cleaning and strong airflow, making them suitable for many kitchens.
Honeycomb Filters vs. Mesh Filters
Mesh filters tend to clog quickly and require frequent cleaning, whereas honeycomb filters offer superior grease capture efficiency and a longer lifespan.

Proper Maintenance of Honeycomb Filters
Cleaning Frequency
Regular cleaning is essential to maintain performance. The frequency depends on kitchen activity and grease output, but a general rule is to clean filters at least once a week.
Best Cleaning Methods
Avoid using high-pressure cleaners or abrasive cleaning agents, which can damage the filter media. Instead, use appropriate cleaning solutions and gentle washing methods to extend the filter’s life.
Signs of Wear & When to Replace
Inspect filters regularly for signs of damage, such as warping, corrosion, or reduced effectiveness. Replacing worn-out filters ensures continued efficiency and kitchen safety.

Common Misconceptions About Honeycomb Filters
- Myth: Honeycomb Filters Are Harder to Clean Than Baffle Filters
Honeycomb filters are designed for easy maintenance and are fully washable, making them a practical option for busy kitchens.
- Myth: All Filters Offer the Same Level of Fire Protection
While honeycomb filters contribute to fire safety by capturing grease, baffle filters are designed to meet specific fire safety standards in some regions.
