create page specific category filter

Hello,

I was wondering how can we create filters based on different page.

Currently I am using this code [woof is_ajax=1 taxonomies=product_cat:379] to create filters on the side and i have excluded some filter in the backend setting.

However for one of my page I only need 1 main category to show in the filter and its sub categories. how can I improve the code to show only one main category on the filters and its subs.

Thanks
