Right Answer:
In Zend Framework, filters are used to modify or validate input data before it is processed. They help ensure that the data is in the correct format and meets specific criteria.

```php
use ZendFilterStripTags;
use ZendFilterStringToLower;

$filterChain = new ZendFilterFilterChain();
$filterChain->attach(new StripTags())
->attach(new StringToLower());

$input = "<h1>Hello World!</h1>";
$output = $filterChain->filter($input);

// $output will be "hello world!"
```

In this example, the `StripTags` filter removes HTML tags, and the `StringToLower` filter converts the string to lowercase.
