Kitchen Filtration Solutions: Metal Mesh, Activated Carbon Cotton and Sandwich Carbon Media
Kitchen filtration requirements vary depending on the cooking process, equipment design, and target pollutants. Some applications require a washable metal filter, while others need activated carbon media to help reduce odors or selected gaseous pollutants.
Healthy Filters offers three types of filtration products for kitchen-related applications: metal mesh filters, activated carbon cotton filters, and sandwich carbon media. Each has a different structure and function, allowing customers to select a suitable solution according to their equipment requirements.
Metal Mesh Filters in the First Stage
Kitchen hoods use metal baffle or mesh constructions selected for the appliance and applicable safety requirements. Healthy Filters lists HF-JS as a washable G2 metal mesh prefilter made with corrugated aluminum mesh and a stainless-steel support layer. Its catalog data reports about 65% average arrestance for particles above 5 micrometers.
Clean the metal stage according to the cooking load and the approved method for the frame and mesh. Project approval should confirm grease-separation performance, temperature limits, drainage, cleaning access, and the fire-safety requirements that apply to the hood.
Activated Carbon Cotton Specifications
Activated carbon cotton distributes powdered activated carbon through a fibrous sheet. The carbon surface adsorbs cooking odors and selected volatile organic compounds. Supplied as flat sheets or cut-to-size filter pads, activated carbon cotton can be installed in compatible filter frames or housings. Its relatively thin structure makes it suitable for applications where installation depth is limited.
Healthy Filters lists three grades. HF-Z180 has activated carbon content above 70 g/m2, basis weight 180 +/- 10 g/m2, thickness 3 +/- 0.5 mm, and resistance below 12 Pa. HF-Z210 has carbon content above 90 g/m2, basis weight 240 +/- 10 g/m2, thickness 5 +/- 0.5 mm, and resistance below 15 Pa.
Apply these figures with the supplier’s test conditions. Kitchen performance also depends on the target compounds, carbon formulation, humidity, airflow, contact time, grease exposure, and sealing.
Sandwich Carbon Media Construction
Sandwich carbon media is a composite filter material that combines activated carbon with nonwoven layers. The carbon layer helps adsorb selected cooking odors and gaseous pollutants, while the surrounding material provides support and helps contain the carbon within the media.
For kitchen filtration applications, sandwich carbon media can be used in filter designs where odor reduction is required and installation space is limited. Depending on the specific product construction, it may also be combined with a particle-filtration layer to address additional filtration requirements.
Custom Sizes for Different Filter Applications
Filter dimensions and installation requirements vary between kitchen appliances and exhaust systems. Healthy Filters can provide sandwich carbon media in customized sizes to suit different filter designs.
When requesting a custom solution, customers can provide the required length, width, thickness, or an existing filter sample or technical drawing. These details help us assess the suitable media dimensions and compatibility with the customer’s filter frame or housing.
The appropriate media thickness and carbon loading depend on the available installation space, target pollutants, airflow, and pressure-drop requirements. Any additional particle-filtration layer should be selected according to the required particle filtration performance..
Filter Selection and Maintenance
Start with hood dimensions, airflow, fan curve, depth, temperature, humidity, cooking process, odor target, and pressure-drop allowance. Match the metal stage to the grease load and cleaning method. Match the carbon grade to the target gas, service interval, and available space.
Clean the reusable metal stage before grease restricts airflow or reaches the carbon. Replace carbon media at the validated operating-hour limit or odor-breakthrough criterion. Record the installed model, dimensions, airflow, and replacement date.
Healthy Filters can develop a sample from an existing filter or drawing. Sample approval should verify dimensions, sealing, airflow, pressure drop, grease-stage performance, odor reduction, and maintenance access.
FAQ
Can activated carbon cotton replace a metal grease filter
The metal stage captures grease and oil mist near the inlet.
What types of filters are used for kitchen filtration?
Common options include metal mesh filters, activated carbon cotton filters, and sandwich carbon media. Each serves a different purpose. The appropriate choice depends on the application, target pollutants, installation space, and airflow requirements.
Which information is needed for a custom kitchen filter
Provide the current filter or drawing, length, width, depth, rated airflow, fan data, pressure-drop limit, cooking process, target pollutants, cleaning method, and replacement plan.
Does Healthy Filters provide custom filter samples?
Healthy Filters can review customer requirements based on existing filter samples, technical drawings, or specified dimensions. Sample availability and development arrangements depend on the product and project requirements. Contact our team to discuss your application.
