Our focus
Practical grease filtration
Capture grease at source
Guardian Filters capture airborne grease within the extraction canopy, helping to limit the amount travelling into downstream ductwork. Effective filtration forms part of a wider approach to managing grease accumulation in commercial kitchens.
Support planned maintenance
We provide clear guidance on filter sizing, checks and replacement routines suited to your cooking activity. Filtration works alongside extraction inspection and cleaning; it does not replace them or remove the need to meet applicable maintenance and insurance requirements.
Simplify filter replacement
Our replaceable wool media fits within reusable stainless-steel frames. This gives kitchen teams a straightforward replacement process and reduces the washing required for the wool filter media itself.
Tested filtration performance
Our baffle frames are tested and certified to DIN 18869-5, UL 1046 and ASTM F2519, giving customers documented evidence to support their product selection.
Who we work with
We supply filters to a wide range of commercial kitchen operators across the UK and Europe, including independent restaurants, hotel kitchens, contract caterers, pub groups, schools and universities, care homes, and facilities management companies.
