 ## OPTIONS
 #### **--filter**, **-f**=*filter=value*
 
-Filter output based on conditions given.
-Multiple filters can be given with multiple uses of the --filter option.
-Filters with the same key work inclusive with the only exception being
-`label` which is exclusive. Filters with different keys always work exclusive.
-
-Valid filters are listed below:
-
-| **Filter** | **Description**                                                   |

-| label      | [Key] or [Key=Value] Label assigned to a network                  |
-| driver     | [Driver] `bridge` or ,`macvlan` is supported                      |
-| until      | [Until] Show all networks that were created before the given time |

+The `driver` filter accepts values: `bridge`, `macvlan`, `ipvlan`.
+
+The `label` *filter* accepts two formats. One is the `label`=*key* or `label`=*key*=*value*, which shows images with the specified labels. The other format is the `label!`=*key* or `label!`=*key*=*value*, which shows images without the specified labels.
+
+The `until` *filter* can be Unix timestamps, date formatted timestamps, or Go duration strings (e.g. 10m, 1h30m) computed relative to the machine’s time.
