JSP PowerCap Infinity Pre Filters | 100pk

This pack of 100 genuine JSP pre-filters is all you need to prolong the lifespan of the main filters in your PowerCap Infinity Helmet. These inexpensive pre-filters act as a sacrificial first-line defence against the majority of dust and debris that would otherwise be collected by the main filters, preventing them from becoming blocked and blinded.

When replacing the pre-filters, you should always replace them in pairs to ensure protection levels are not compromised. You should NEVER clean either the pre-filters or main filters with compressed air; this significantly reduces the efficacy of the filters.

Installing pre-filters is easy; First you will need to remove the filter cartridge from the helmet assembly by twisting it upward. Then simply remove the cover grille from the filter cartridge. The pre-filters then simply slot into the cover grille. These can then be clipped back into place and the filter cartridges re-attached.
