# How to use filters in Data Activation

Filters let you to control which event types are forwarded through your event connectors. You can create filters separately and then add them to one or more event connectors. This makes it easy to reuse filters or combine them without having to redefine them for each connector. Once you link a filter to a connector, it sends only the events defined in the filter. If no filter is configured, the event connector attempts to send all data.

Note that you can't create reverse or negative filters. This means you select only the events you want to receive, rather than excluding the ones you don't.

**Example:**

You create 3 filters for the following events: `pageView`, `conversion`, and `customer fact`. You then add the `pageView` and `conversion` filters to your Azure Event Hubs connector.

If the following events occur:

- `pageView`
- `pageView`
- `customer fact`
- `conversion`
- `pageView`

The Azure Event Hubs connector receives:

- `pageView`
- `pageView`
- `conversion`
- `pageView`

The `customer fact` filter exists but isn't linked to the connector, so those events aren't forwarded.

## Instructions

### Create a filter

1. In Data Activation, go to **Connectors** and select **Filters**.
2. Click **Create**.
3. Enter a name that describes the events or type of events you're adding.
4. Click **Add an event**.
5. Select the event. For facts and engagements, also select the event type.
6. Repeat steps 4 and 5 to add more events to the filter.
7. Click **Create filter**.

### Edit or delete a filter

To edit a filter:

1. In the filter list, click the **Pencil** icon for the filter you want to edit.
2. Add or remove any filter criteria.
3. Click **Update filter**.

To delete a filter, click the bin icon on the right side of the screen.

### Add a filter to a connector

A filter doesn't take effect until you link it to a connector. Once linked, the filter becomes active immediately, and only the defined events are sent to the destination.

To link a filter:

1. On the Data Activation platform, select **Connectors** in the left-side navigation bar.
2. Click the connector you want to apply the filter to.
3. Click **Add filter**.
4. Click **Update**.

You can check whether a filter is already in use on the **Filters** page and looking at the "used in" icon.
