a carbon fibre filter. To purchase a carbon fibre filter or a new HEPA filter
please contact the EHS Spares Department 0870 744 0161. This product
can be operated without the HEPA or Carbon filter, but the washable nylon
filter must be installed.
1. Remove the grille with the nylon air filter.
2. Behind the frame is a space to insert the optional filter.
3. Insert optional filter (HEPA or Carbon, but no both).
4. Refit the nylon air filter.
Do not wash the optional filters as they will be damaged. The optional filter
should be changed every 6-12 months depending on frequency of use.
