Duplicates from smart filter /filter/clear/apply/ how right for SEO?

Question

1C-Bitrix

Good afternoon. I scan the spider frog'om site and see that the category pages with a postscript at the end /filter/clear/apply/ form a duplicate, i.e. https://site.ru/catalog/category_1/filter/clear/apply/ is a duplicate https://site.ru/catalog/category_1/
The filter from indexing cannot be closed, because additional ones are formed on its basis. pages. What is the best way to proceed in this case, 301 redirect?

Answer 1

/ apply / I would not advise, because you will close all filters, but safely close / clear / apply /, because this means for Bitrix to clear the filter parameters, read show the catalog page without any conditions, hence the duplicate of the main page .
