On the toolbar, click Filter > New Filter.

The Create New Filter form will be displayed.

In the Create New Filter form, under Show rows that match, select the conditions that you want to apply to the data in the sheet and then click Apply to see the results of the filter.

Unnamed Filter will appear in the Filter menu to indicate that your data is being filtered according to the conditions you specified.
