Filter Square Icon

Q: When should I use it instead of a similar icon?

Use it for a bare filter toggle on a mobile app bar or map overlay, where the square is the hit area; and a filter control in a toolbar of square framed glyphs, matching the plus and trash squares. For ordering a list by date, name or priority, use the Sort icon. For a labeled toolbar control that already draws its own border, use the Filter icon. For view settings such as density, columns and grouping, use the Sliders Square icon.

Funnel inside a rounded square, for filter toggles, filter panels and active filter buttons. Available in 4 styles (outline, solid, duotone and filled) as a React component you install with the shadcn CLI.

Filter Square icon FAQ

What does this icon show?

Funnel inside a rounded square, for filter toggles, filter panels and active filter buttons. Typical uses: filter toggle in a grid toolbar, open filter sidebar button and active filter state on a table.

When should I use it instead of a similar icon?

Use it for:

A bare filter toggle on a mobile app bar or map overlay, where the square is the hit area
A filter control in a toolbar of square framed glyphs, matching the plus and trash squares

For ordering a list by date, name or priority, use the Sort icon. For a labeled toolbar control that already draws its own border, use the Filter icon. For view settings such as density, columns and grouping, use the Sliders Square icon.

Which styles does it come in?

4 styles: Outline, Solid, Duotone and Filled. Every style is drawn on the same 24 by 24 grid and installs as its own file, so you can switch styles without touching the layout.

How do I install it with the shadcn CLI?

Copy the install command from the panel above, in the style you want, and run it in your project. The shadcn CLI adds the icon as a React component that you import and render like any other. It draws in the current text color, so your text color and size classes style it. Icon installs need a ReUI Ultimate license.

What icons go well with it?

Plus Squared and Trash Square sit beside it in the same toolbar or menu. More from the same family and the Actions set: Filter, Filter Edit, Filter Search and Filter Tick.

When was it added?

It joined the ReUI icon library on June 30, 2026.
