How to filter by attribute VALUE, not ID?

I have some external webpage and I want to redirect user from this webpage to M2 category with filter. However I see that Magento for filtering is using internal attribute IDs. Is there any way to filter categories by attribute value, not id?

When on my website user choose brand “Audi” I would like to redirect user to

http://shop.com/oil-filters.html?brand=Audi

but currently I need to know Audi‘s ID and redirect to

http://shop.com/oil-filters.html?brand=2316

which is not what I want.
