# Filters

After configuring the placement and product groups, you can, if desired, refine your recommendation results by adding filters.

Filters can be applied to each product block independently or to the entire recommendation.

You can then tailor the results of the blocks or the recommendation based on criteria such as category, price, size, and more.

*ex: the filter is applied to the Test 1 block, allowing the results of this block to be filtered based on product price. In this case, Block 1 should only display products priced below €16.*

You also have the option to combine filters using the "OR" button.

Alternatively, you can make the filter dynamic by assigning it the variable used by the algorithm.

For more information about filters, you can visit the page: [Most popular filters](/recommendations-and-merchandising_deprecated/recommendations/introduction/most-popular-recommendation-filters.md).
