There has been a lot of research in recent years with regards to indoor air quality and the benefits of healthy work spaces. As a result, wool is re-emerging as the preferred choice for many insulation and commercial use applications, including the kitchen!

 

From a food safety and hygiene perspective, wool is naturally resistant to bacteria, mould, and mildew.

It also has an innate ability to absorb and neutralise many harmful pollutants from the air, benefiting those who use the space (in this case, the kitchen – where the magic happens).

Wool is also oleophilic – meaning that it has an affinity for oils, making it a great choice for grease containment. The proof is in the pudding (pardon the pun) with Shepherd Filters’ ability to capture up to 98% of grease particulates before they have the chance to accumulate inside the kitchen exhaust system where they become a fire hazard.

So why should you invest in a disposable kitchen grease filter solution made of wool?

 


Shepherd Filters provide fire protection

 

Wool is widely recognised as the most flame resistant and difficult to ignite (570-600 °C), wool’s inherent fire resistance comes from its naturally high nitrogen and water content. Because of this, wool requires higher levels of oxygen in the surrounding environment to burn.

Wool may be ignited if subjected to a very powerful heat source, but it does not normally support flame. If smouldering occurs, it usually continues only for a short time. In addition, wool’s highly cross-linked cell membrane structure will swell when heated to the point of combustion, forming an insulating layer that prevents the spread of flame.


Wool kitchen grease filters are biodegradable

Tests show that with the ideal conditions, wool products are almost completely degraded after six months in the ground.

Research shows that wool functions as an effective soil conditioner and fertiliser, slowly releasing sulfur, nitrogen, phosphorous and potassium as it biodegrades.

This fiber has been shown to biodegrade at a significantly faster rate in soil, composting and even marine environments. Biodegradable in both salt and freshwater, wool will not contribute to micro-plastic contamination.


Wool kitchen grease filters are sustainable

 

Sheep are part of the natural carbon cycle, consuming the organic carbon stored in plants and converting it to wool – a renewable product. Sheep grow their woolen fleece yearly and sheep are abundant in Australia, a country that prides itself on its wool industry (regarded among the world’s best).
