Multiple models

You can use report-level filter on filter pane. Or you can have a filter on one page and copy it on other pages, it will ask for the option to sync, click ok. Then choose a value on one page.

Hi, Anonymous 

I'd like to suggest you use page level filter or sync slicer to filter three separate pages.

About the three separate models, there are eight different data reduction techniques. Please refer to the article .

• Remove unnecessary columns
• Remove unnecessary rows
• Group by and summarize
• Optimize column data types
• Preference for custom columns
• Disable Power Query query load
• Disable auto date/time
• Switch to Mixed mode

In addtion, It is suggested to use a star model. Star schema design and many related concepts introduced in this article are highly relevant to developing Power BI models that are optimized for performance and usability. You may refer to the article .

Best Regards

Allan
