Description

Most WooCommerce filter plugins are heavy, slow, or overloaded with features you don’t need.

Janssen Fast Filters is built differently.

It delivers fast AJAX product filtering with clean architecture, optimized queries, AND logic, and auto-apply — without page reloads and without unnecessary bloat.

An ideal alternative to the default WooCommerce layered navigation widget.

  • AND filter logic (combine multiple attributes intelligently)
  • Auto-apply filters (no “Apply” button required)
  • Category filter with optimized hierarchical rendering
  • Product attribute filters (color, size, custom attributes, etc.)
  • Price range slider with min/max inputs
  • Sort by price, popularity, rating, or date
  • Mobile-friendly slide-in filter panel
  • Active filters display with one-click removal
  • Gutenberg block for easy placement
  • Fully translatable
