With the introduction and recent improvements of Shopify Online Store 2.0, creating filters in Shopify is a piece of cake. Shopify merchants can easily enable 4 default product filters, namely Availability, Price, Product Type, and Vendor (Brand). Adding custom product filters in the Shopify collection and search result pages, however, is a bit trickier. This article will cover 2 code-free ways to do it. Keep scrolling to find out.

What are custom filters on Shopify?

Obviously, the 4 default Shopify filters are not useful enough for online shoppers to refine a long product list according to their preference. Therefore, merchants need the help of custom product filters. These are filtering criteria based on custom product options such as color, size, specifications, and product metadata such as percent sale, review rating, and inventory locations.

How many ways are there to add product filters in Shopify?

If you are a non-tech-savvy Shopify user, there are two common ways to help you with adding custom product filters in Shopify.

Using a third-party app

The first one is to install a third-party app like Product Filter & Search by Boost Commerce. This is what the majority of Shopify merchants had been using before OS 2.0.


  • User-friendly UI/UX
  • Unlimited filter options by tag, metafield, etc
  • Dedicated filter trees for each collection
  • Ability to customize the look and feel of your filters
  • Many advanced features (merchandising, analytics, etc) to boost online product discovery
  • Integrations with other apps to take advantage of product metadata
  • Top-notch customer service with technical support & customization


  • Subscription-based pricing
  • As there are a lot of useful features, it may take some time to explore and take advantage of all

Using Shopify's native app

OS 2.0 and now the release of the Shopify Search & Discovery app have opened a new way for small merchants to add filters to Shopify stores.


  • Free usage
  • Basic filter options including Filter by Metafields
  • Some advanced features such as product recommendations


  • Filters won’t show when the product number on the collection exceeds 5,000
  • The number of filters is limited to 4 default ones and up to 20 custom filters
  • Can’t change the display and the styling of the filter options
  • Hard to connect product metadata on other apps to create filters

Based on the advantages and disadvantages of both options, we would recommend Shopify Search & Discovery app for small-volume stores during the early stage. As your shop grows with more products and more traffic, you will need a more sophisticated and scalable tool like Boost Product Filter & Search.

Indeed, the app offers a 14-day free trial without credit card details, so you can have time to test all the juicy features. Moreover, you can get the sales number generated by the app on its analytics to decide if it’s a great tool to stick with.

How to add custom filters in Shopify native app?

  1. Go to Shopify Search & Discovery app. As this app is pre-installed for Shopify stores (which raised concerns about privacy among Shopify merchants), you don’t need to install it.
  2. Click Filters on the left-hand sidebar or View filters on the main dashboard to edit Shopify filters.

3. 4 default filters are enabled by default on the filter dashboard. To add more, click Edit filters. Here you’ll see all the filter options you can enable (it’s much less than what the Boost filters offer). Ticking the checkbox is the first step to making the filter visible on your storefronts.

4. To display filters created by Shopify native apps, you go to Online Store > Themes on the left sidebar. Click Customize on the theme you want to display filters on. Choose Collection > Default collection to enable filters on Collections. Or choose Other > Search to enable filters on Search results. Each theme will have a different section setting to allow you to turn the filtering on and off. Below is the demonstration for the Crave theme.

Some FAQs related to custom Shopify Filters

How can I create Filter by metafield on my Shopify store?

To create a Shopify filter by metafields, you have to first add the metafield either in the Shopify Metafield or by using a metafield app. Refer to the following instructions for more details:

How can I create price range sliders or any range sliders in the filter trees?

How can I group some filter values together?

You can try Merge values under Filter on Product Filter & Search by Boost Commerce to group different filter option values so the value list on your store’s front-end won’t confuse users. “Light blue” can be combined with “Dark blue”, “Turquoise”, and “Sapphire” into “Blue” using Merge values. Read the full instructions here.

Again, the Shopify Search & Discovery app doesn’t have this functionality.

How can I create custom swatches on my Shopify filter?

Swatch settings on Boost Product Filter & Search support filters using “swatch” as the display option. It allows you to pick colors or upload images to show on the swatch. This is a big advantage over the Shopify native app.
