The replacement option being LED’s, with their longer life, considerably lower running costs, no mercury content, safer for the operator and environment and being a lot more robust.

Typical HEPA specification will be 99.997% efficient at a particle size of 0.3 micron, let us know if you need anything with a different specification. ULPA filters are also produced, where needed, typically 99.998% efficient at a particle size of 0.12 micron.


Carbon Filters

Carbon Filters are used to remove the vapours and gases of materials, where they are flammable, toxic or just smell bad! Carbon filters are one of the most important safety devices in the workplace, where fumes are deemed to be hazardous according to Control of Substances Hazardous to Health (COSHH). We offer replacement activated carbon filters for all brands of fume cupboards and safety cabinets as well as many other applications.

Our Carbon Filters are manufactured from high quality activated carbon in the UK. Produced within an ISO 9001 accredited environment ensures full process control is adhered to and allows raw material traceability. CE and ISO certification guarantees consistency of performance for adsorption capacity and particle size. Our filters also meet the requirements of British Standard BS7989:2001 and European Standard AFNOR NF X 15-211.
