A mask without sufficient filters is useless!
The past showed that in cases of crisis filters for gas masks are sold off usually within shortest time (world-wide). It is to be thought from there recommendable also directly of spare filters! The manufacturer data concerning minimum durability of filter are at 4 years (legal regulation); however the filters - if these unused, original to be locked and drying stored - are far longer durable and realistic can one from 6-8 years proceed.
The filters contain activated charcoal and this tighten air humidity. The service life - i.e. like for a long time one with a filter to breathe can - lets itself specify very with difficulty. That hangs off of the kind of the pollutants, the concentration, and the relationship of dust or soot load of air. In the case of brief use of the filters these can be locked afterwards with the plastic lids again and used naturally repeatedly.
An indication that the filter is for exchange, is usually if the breath resistance becomes higher. The universal filter D500 is one of the high-quality and umfassensten filters in many ranges.
