The pack comprises the system filter, made in collaboration with Fernox, and a bottle of Fernox FI Inhibitor and a bottle of Fernox F3 Cleaner. The contents of these handy-sized 265ml bottles fit exactly into the filter’s chamber, so there’s no wasted chemicals, you use exactly what’s needed. Whether the filter is bought as part of the Intergas System Filter and Chemical Pack or on its own, two more years will be added to the boiler’s warranty.
