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

Low air flow resistance No fan upgrade required

1. Inherently flame-retardant1. Tends to smolder or char2. Self-extinguishing
