Why default WooCommerce filtering costs you conversions
Out of the box, WooCommerce filtering leans on heavy queries and full-page reloads. Every reload is a pause in the shopping flow — and on mobile, pauses turn into bounces. As your catalog grows, the query load grows with it.
- Full-page reloads that interrupt the mobile shopping flow
- Heavy attribute queries that strain shared hosting as the catalog grows
- Rigid widgets that do not adapt to the category a shopper is browsing
A filter that stays fast as the store gets bigger
Rotozoom Product Filter narrows each query to the category the shopper is actually browsing instead of scanning every attribute in the store, and — on Pro — caches the rendered result fragment. Filtering happens over AJAX with the URL kept in sync, so results update in place and every filtered view is shareable and bookmarkable.
Category-context queries
The filter only queries attributes relevant to the current category view, so response time tracks the category — not your whole catalog.
AJAX with URL sync
Results update in place while the address bar reflects the active filters — so a filtered view can be linked, bookmarked and indexed.
Fragment cache (Pro)
Pro caches the rendered product fragment per filter state, so common filter combinations return without re-rendering.
Filter by anything
Combine product attributes, a price range slider, categories and stock status — configured from the WordPress admin, no code.
Where it fits
A store with thousands of SKUs across many categories.
→ Shoppers filter within a category without the query touching the rest of the catalog, keeping the archive responsive on mobile.
Fashion or electronics with size, colour, spec and brand attributes.
→ Buyers combine several attributes at once and land on exactly the products they want, without a reload between each choice.
How Rotozoom Product Filter compares
Two capable alternatives, and where each one fits better than we do.
The go-to for sites built on custom fields (ACF, Toolset, Pods) and content types beyond a product catalog — faceting far past standard WooCommerce.
Rotozoom → Rotozoom focuses purely on WooCommerce: it narrows each query to the category being browsed and, on Pro, caches the rendered fragment — at a lower price point.
A widely used filter with a free tier on WordPress.org, broad theme compatibility and a large install base — a low-risk pick, especially if you already run YITH plugins.
Rotozoom → Rotozoom keeps a light footprint and scopes each query to the category the shopper is browsing.
Choose FacetWP if your site is built around custom fields beyond WooCommerce; choose YITH if you want a free starting tier or already run YITH plugins. Choose Rotozoom for fast, WooCommerce-native filtering at €47/yr.

Frequently asked
Will it slow my database down as the store grows?
It is built to avoid that. Instead of scanning every attribute in the catalog on each request, it narrows the query to the category the shopper is viewing, and Pro adds a per-filter-state fragment cache so repeat views skip re-rendering.
Does it work without a page reload?
Yes. Filtering runs over AJAX and updates the product grid in place, while the URL stays in sync so filtered views can be shared, bookmarked and indexed.
Is there a free version?
Yes. The free version on WordPress.org covers core filtering; Pro adds the fragment cache and higher attribute limits.
Which themes does it support?
It works with standard WooCommerce archive templates and is tested against common themes; it targets the product loop rather than a specific theme.
Can shoppers filter products by category on the shop page?
Yes. The filter reads the category a shopper is browsing and narrows results to it, so category filtering works on the main shop page and on category archives — without a full-page reload.
Can I let shoppers hide out-of-stock products?
Yes. Stock status is one of the available filters, so shoppers can narrow the grid to in-stock items alongside attributes, price and category.
