Should filters be on left or right?

4. Filter bars better showcase filters. By making the filters more prominent on the page and by making them available as the user scrolls a filter bar does a better job of showcasing filters. Presenting filters left to right also makes it very easy for users to quickly see what options are available.

What is filtering lists?

Filtering a list lets you find and work with a subset of the data in your list by displaying only the records that contain a certain value or meet specific criteria.

Where to put filters UX?

In terms of the positioning of your filters component, where it should be placed on the page, you basically have three options. It can either be as a left-hand vertical sidebar, directly inline with the content at hand, or as a horizontal filter bar. The decision depends on your context and scalability needs.
