Commercial Kitchen Foam Metal: Frequently Asked Questions

How does foam metal compare to traditional aluminum mesh filters?

Foam metal filters outperform traditional aluminum mesh in every category:

Criteria Foam Metal Aluminum Mesh
Grease Capture Efficiency 93-97% 70-80%
Fire Rating A1 Non-combustible Combustible
Lifespan 3-5 years 6-12 months
Cleaning Frequency Every 3-6 months Every 2-4 weeks
Airflow Resistance Low (maintains CFM) High (clogs quickly)

While foam metal has a higher initial cost, the 3-5x longer lifespan and reduced maintenance make it more cost-effective over time.

Are foam metal filters NFPA 96 compliant?

Yes, our stainless steel foam metal filters are fully compliant with NFPA 96 standards.

NFPA 96 requires that grease filters for commercial kitchen exhaust systems:

  • Be listed and labeled in accordance with UL 1046
  • Have a grease removal efficiency of at least 90%
  • Be constructed of non-combustible materials
  • Be readily accessible for inspection and cleaning

Our stainless steel foam metal filters meet all these requirements:

  • Grease Removal: 93-97% efficiency (exceeds 90% requirement)
  • Fire Rating: A1 non-combustible (stainless steel)
  • Accessibility: Standard sizes fit all commercial hoods
  • Cleaning: Easy to remove and clean with degreasers

We provide complete documentation including material certifications and test reports for your local fire marshal inspection.

How do I clean foam metal kitchen hood filters?

Foam metal filters are easy to clean and maintain. Here's the recommended cleaning process:

Step 1: Remove Filters

  • Turn off exhaust fan and allow filters to cool
  • Remove filters from hood (standard mounting systems)
  • Place filters in appropriate cleaning container

Step 2: Degreasing Solution

  • Use commercial degreaser or hot water + detergent
  • Soak filters for 30-60 minutes (or as recommended)
  • For heavy buildup, use pressure washer on low setting

Step 3: Rinse & Dry

  • Rinse thoroughly with clean water
  • Allow to air dry completely before reinstalling
  • Do not use high heat drying (can damage adhesives)

Cleaning Frequency:

  • High-volume kitchens: Every 1-3 months
  • Medium-volume kitchens: Every 3-6 months
  • Low-volume kitchens: Every 6-12 months

Pro Tip: Keep a spare set of filters to use while cleaning, minimizing kitchen downtime.
