Answer 1

I think you need something like this:

SELECT * FROM product_filter p 
INNER JOIN filter_group f ON f.filter_id = p.filter_id 
WHERE p.filter_id IN (11,22,33,44)

If you just want to get back some columns, change the *

Answer 2

SELECT p.product_id, p.filter_id, f.filter_group_id
FROM `product_filter` p
JOIN `filter_group` f
ON p.filter_id = f.filter_id
