The BST Canister greatly reduces the frequency of labor intensive film inspections. With The BST Canister’s vented filter technology:

The chance of finding deteriorated film is greatly reduced; therefore, it reduces the cost of intervention.
The need for expensive cleaning or replacement is reduced by extending the life of the filmtherefore, costs associated for duplication prints are also reduced.
The canister is constructed from quality stainless steel; therefore, the cost of replacing corrosive cans is eliminated. 

Outward directional filtration helps vent the acidic gases. Dust and other particulates are prevented from entering the micro-environment of the can. Optional replacement filters also absorb gases. The filters are chemically inert, so like the stainless steel can, they will not interact with the film or contribute to degeneration. The low–cost filters can be periodically replaced.

Fire safety is a major concern, especially with cellulose nitrate films. Gases which build up in a closed can reach levels of concentrations where a small spark can ignite a fire or explosion. A cellulose nitrate film base fire is practically inextinguishable, as the fire generates its own oxygen. The BST Canister, combined with the proper air–change ventilation vault, increases safety by exhausting dangerous gases.
