It does not have any filters - it just does not need them, because in SCBA you alway breathe fresh air from the air tank on your back. And the cartridges eventually get old and need to be replaced.įinally, there are tactical SCBA - a fully standalone breathing apparatus. However, APR respirators are only effective when used with a proper type of a filter. Then, there are Air-Purifying respirators, or APR respirators that use a system of CBRN filters to eliminate most hazards from the air.
Such respirators provide only basic protection from mechanical or biological contaminants, but do not offer any advanced protection from toxic gases, riot agents or smoke. Example of this type of a respirator is a face mask we all got used to during the pandemia. The simplest ones are those that protect only against particulates.
You should know that there are different kinds of respirators on the market. The CBRN cartridge in air purifying respirators is usually sold individually as well as in set with the respirator.
In canister respirators the cartridge-type filter allows for quick and easy changing of filters. Such filters must be replaced in time, though, in order to maintain the highest level of protection of APR respirators. This is critical for law enforcement officers performing their duty in smoke pollution conditions, or during riots when the tear gas can be used.Ī tactical respirator is equipped with a CBRN filter capable of protecting lungs from the majority of chemical, biological, radioactive and nuclear hazards, hence the name. A tactical respirator is a protective device designed to prevent inhaling toxic gases, combustion products and dangerous particulates.
