Why Wool?
Nature engineered the ideal material for commercial kitchen filtration.
Wool is not simply a natural fibre. Its complex structure, natural fire-retardant properties, and ability to attract and retain grease make it particularly well suited to commercial kitchen extraction systems.
The wool used in Ecofleece filtration media brings these natural performance benefits together with responsible sourcing, coming from Responsible Wool Standard certified farms and land with verified ecological outcomes.
This combination of natural performance and positive impact makes wool the ideal material at the heart of Ecofleece filters®.
WOOL’S NATURAL ADVANTAGES
Naturally Fire Resistant
Wool fibres resist ignition and do not melt or drip when exposed to flame.
Wool contains naturally high levels of nitrogen and moisture. These characteristics make it far more resistant to ignition than many synthetic materials.
When exposed to flame, wool tends to self-extinguish once the heat source is removed.
- higher ignition temperature than many synthetic fibres
- does not melt or drip under heat
- naturally self-extinguishing behaviour
- contributes to safer filtration environments
Attracts and Holds Grease
Wool fibres naturally attract grease particles carried in kitchen airflow.
The natural chemistry and structure of wool fibres allow them to capture and retain grease droplets within the filtration media.
This helps intercept airborne grease at the canopy before it enters ductwork.
- natural affinity for grease particles
- absorptive fibre structure
- helps capture airborne grease at source
- supports cleaner extraction systems
Unique Fibre Structure
Microscopic scales on wool fibres create a complex filtration surface.
Wool fibres have a distinctive outer layer known as the cuticle. This surface contains microscopic scales which increase surface area and create natural points for particle capture.
This complex fibre structure makes wool highly effective for filtration applications.
- scaled fibre surface
- increased surface area for particle capture
- natural filtration behaviour
- durable and resilient fibre
Stable in High Heat
Commercial kitchens produce intense heat and airflow.
Wool fibres maintain their structure and filtration performance in elevated temperature environments commonly found in commercial kitchens.
- heat-resistant fibre
- maintains structure at elevated temperatures
- suitable for demanding kitchen environments
Captures Odour, Moisture and Vapour
Kitchen extraction systems contain odorous grease, vapour and moisture.
Wool performs effectively in mixed grease and vapour environments, supporting consistent filtration performance in humid extraction conditions.
- breathable natural fibre
- performs well in humid environments
- handles vapour and grease together
- supports consistent filtration performance

Renewable Natural Fibre
Wool is a renewable fibre that grows back every year.
Wool is a naturally renewable fibre that regrows each year. Responsibly sourced, it offers a natural alternative to fossil-fuel-derived filtration materials.
- Renewable natural material
- Biodegradable fibre
- Supports responsible sourcing
- Connected to verified
- ecological outcomes
FROM FARM TO FILTER
The wool used in Ecofleece begins with The Woolkeepers®, a purpose-driven community working to raise standards, improve traceability and create long-term value for wool growers.
Carefully sourced and prepared for filtration, its natural fibre structure is transformed into high-performance media designed to capture airborne grease while maintaining airflow.
Its responsible origin adds another dimension to its performance. The wool comes from Responsible Wool Standard certified farms, with ecological outcomes verified through the Savory Institute, connecting Ecofleece with responsible farming, land stewardship and positive ecological change.
WHY ECOFLEECE USES WOOL
Ecofleece uses specially prepared wool filtration media designed for commercial kitchen extraction systems.
By combining the natural properties of wool with a purpose-built filtration design, ecofleece helps capture grease at the canopy before it enters ductwork.
Key Benefits:
- Captures up to 98% of airborne grease*
- Helps reduce grease entering duct systems
- Supports fire risk management by controlling grease at source
- Makes grease loading visible to support timely pad replacement
THE ECOFLEECE STORY
Wool’s natural performance is only part of the story.
Ecofleece combines purpose-designed wool filtration media with preventative grease capture, responsible sourcing and clearer system maintenance.
