Reduce the interaction cost

When designing filter panels, try to minimize the interaction cost for your users. Avoid forcing them to save each filter preference individually or requiring excessive button clicks. Employ intuitive icons and tooltips for clarity, and consider implementing auto-updating of results as filters are applied or removed. Keeping the user experience smooth and friction-free is paramount in enhancing usability and satisfaction among your users.

However, auto-updating filters may not be suitable for complex tasks involving extremely large data sets, pagination, or heavy server load. In such cases, an explicit Apply button can prevent performance issues and poor user experience.
