Howard, this link SHOULD provide a list of distributors for the cartridges you desire,,

PS its up to you to sort through the list and find one close to you,, Hey I only do the easy part LOL

Those cartridges are extinct.  It looks like AOSafety got absorbed into 3M.  I guess I'll get me a 3M mask and the appropriate cartridges to go with it.

Planned obsolescence, have the same problem, found a set of cartridges at a local lumber yard so am set for one more airplane but after that will be forced to buy a new mask. Nothing is easy any more, everything is complicated.

Howard,

If you wear it, we want pictures.

Please keep in mind, that all cartridges,, whether on a disposable mask or a replacement cartridge are rated for a specific number of hours of exposure. That exposure starts when it is exposed to air, ,and runs its course regarless of it is filtering your incoming breath or not,, ( or outgoing breath too for that matter  )

To prolong the life of the mask,, after using it, do not just put it on the bench,, put it in an air tight container. Once it has "filtered " the air inside the container,, the use of its filtering "time " stops until you expose it to air again.
If you just leave the thing in open air,, it continually filters all the air it sees( in other words its more like a contamination function with the filter media absorbing chemicals from the surrounding atmosphere even while just sitting there inert)

Howard,,
its not the paint that is toxic, poisonous and evil,, its actually semi safe,, its the catalyst,, so I guess you could always spray your clear with out the catalyst?

It might be kind of hard to keep the fuel from attacking it,, but at least the catalyst wont attack you,, 

and NO FOLKS, I am not serious about spraying it without catalyst,, its a joke son,, its a joke

well that is good,,
of course the real issue is the LONG term affects,, so we will stand by,,
