Drupal Facets Block Show everywhere (in non search page)
Depends on what module you are using with facetapi. If you are using search_api, then when creating the view you can add a view display of type "Facets Block" (like you would add a page, block or panel display).

Using that display you can add a facet block anywhere on your site, even on non search pages. And you can also set the search_path you want to redirect to when using the facet block.
