# eth_uninstallFilter | Base

Base API method `eth_uninstallFilter` removes a previously installed filter, stopping further notifications. This method is crucial for managing resources and avoiding unnecessary data processing from filters that are no longer needed.

<Warning>
  **Disclaimer**

  Note that the default interactive example in this page will not work as the filter will be expired.

  To test `eth_uninstallFilter` in this page, first create a new filter using one of the following:

  * [eth\_newFilter | Base](/reference/base-newfilter)
  * [eth\_newBlockFilter | Base](/reference/base-newblockfilter)

  Then use the fresh filter ID as the parameter for `eth_uninstallFilter`.

## Parameters

* `filterId` — the ID of the filter to be uninstalled. This ID is returned by filter creation methods such as `eth_newBlockFilter`, or `eth_newFilter`. For this example, a random value `"0x1a2b3c"` is used.

## Response

* `result` — a boolean indicating the success of the filter removal. `true` if the filter was successfully uninstalled; otherwise, `false`.

## Use case

The `eth_uninstallFilter` method is essential for:

* Applications that dynamically create and remove filters based on user interaction or specific conditions to manage system resources efficiently.
* Services that need to clean up filters to prevent processing outdated or irrelevant data.
* Developers who are testing or debugging Base filters and need to reset their filter setup.
