# My Feeds > Parameters > Filters - Cdiscount Flux

Sometimes you may want to stop products of certain brands or suppliers from being sent to your marketplaces. The Filters page allows you to block specific manufacturers and suppliers from your product feed.

As shown below, the interface is split into two sections: **Manufacturers/brands** and **Suppliers**.

### How Filters Work

Select the manufacturers/brands & suppliers to exclude. The corresponding products will not be imported into Cdiscount Flux and will be excluded from marketplaces, but items already online will not be affected.

### How to Exclude a Manufacturer or Supplier

2. Select or type the names of the brands or suppliers you want to block. 
3. To unblock a manufacturer or supplier in the future, simply click the small **X** on their blue tag.

> ⚠️ **Important Note:** These filters only prevent the import and export of products. If a product is already active and listed on a marketplace, adding a filter now will not automatically delete or remove it from the platform.
