I feel that having 'Filter' and 'Filter' is repetitive. Any suggestions on making this more intuitive for users?
Most of the time, the user will understand that the section is a filter section when it has the action button labelled 'Filter'. Having a label Filter as well as a filter action button is more of redundancy I could say.
If you wish to retain the label and if the page is not content intensive site, then you can load the contents dynamically when the user applies the filter. You wouldn't require an action button here.
If your page is content intensive, the above mentioned technique will not be advisable since it will consume more page load time which will affect the experience of the user adversely
I often see the caption "Apply" on the button. That means "the filters are applied".
Take a look at Material design - Text for buttons and related elements.
I would either avoid the use of the button if you can update the results smoothly as the user selects from the dropdown (as Google does);
or remove the label and just show the Filter button.
I think "Filter" is ok for the title, but for the button is better to use "Search", "Find" or "Explore".
