Most professionals who work with asbestos don't recommend "purge it from everything everywhere." Rather, the usual recommendation is to leave it intact and don't touch it, unless it's going to be disturbed in a way that'll release the fibers anyway (eg. imminent renovation or demolition, accessible to small children). Even then, oftentimes abatement consists of encapsulation, i.e. just wrap it in some physical barrier that will prevent it from being disturbed. It's banned in new construction, but choosing to use something different when building anew is a lot less expensive than ripping it out of existing construction.
