7 NaturalSorb Air Filtration Performance Why Wool? – 5 Reasons 1.Oleophilic - Strong and unique attraction between grease and wool  Wicks grease into fibers before clogging spaces between for longer usable filter life 2.Environmentally-responsible  Natural materials  Wool  Soy & Whey spray (adhesive)  Easy, bio-degradable disposability (landfill)  Reduces air and water pollution 3.Cost-effective  Plentiful and renewable resource  50 million sheep in New Zealand 4.Low air flow resistance  No fan upgrade required 5.Inherently flame-retardant  Tends to smolder or char  Self-extinguishing Clean on back Greasy on front

10 NaturalSorb Air Filtration Performance Typical Metal Baffle Filter (UL1046) with NaturalSorb Air Filtration NaturalSorb Air Filtration is 3 to 4 times more effective at stopping grease particulate

11 NaturalSorb Air Filtration Performance Scene 1 - Grease sprayed onto filter. Scene 2 - Cook top grease fire started. Scene 3 - Fire rages. Flames impinge wool filter above fire source. Scene 4 - Wool filter chars, smolders, and disintegrates, but does not burn. Scene 5 - Although adjacent filters are loaded with grease, flame does not spread. What happens to wool filter loaded with grease during a cook top grease fire if fire-suppressant system fails? (video at
