====Filters==== A **filter** modifies the data in a [[funnel|funnel]] after it has originated from a [[source|source]]. Some filters may only make subtle changes to your [[data|data]]. Some may make drastic transformations, completely changing the nature of the information. Some may in fact **stop** your funnel from operating. This is often found in filters that delay or alter the timing of your output, such as [[filter_throttle|Throttle]], which ensures that analytics are not written too quickly. After passing through your filters, your data proceeds to the [[sink|sinks]].
