Enabling this filter will limit Pandora to playing music that could play on daytime broadcast radio. This can only be applied to the entire account and not specific stations.
On the Web:
To enable the explicit filter, sign in to your account, click your email address in the top right corner and select Settings.
Select "No. Do not allow explicit content." You will have the option to protect this setting with a PIN code.
On the iPhone or iPod:
To enable the explicit filter, launch the Pandora app, tap on Settings, then select ‘Account.’
Next to “Allow explicit content” toggle the switch to OFF. Make sure to tap ‘Save’ when finished.
