# Logic: Not

> Filters items that do not match the filter.

Reverses a condition. It keeps an item only when the condition you choose does **not** match, and filters out the items that do match. Use this to express the opposite of a check, for example "keep every order that is **not** cancelled" by wrapping a "status equals cancelled" condition in this one.

This documentation describes: [Schema](/schemas/filter/not-condition)

## Fields

<FormField property="filter" label="Condition" required diType="filter">
  The condition to reverse. You pick a single condition here; an item is kept when that condition fails, and filtered out when it matches.
</FormField>

## Sample data

This filter answers yes or no for each item, so there is no before and after. The example wraps a "status equals paid" condition, so it keeps everything that is **not** paid.

| Field     | Value                  |
| --------- | ---------------------- |
| Condition | `status` equals `paid` |

| Incoming item             | Result         |
| ------------------------- | -------------- |
| `{ "status": "paid" }`    | does not match |
| `{ "status": "pending" }` | matches        |
