<p>A filter element for use in the filtering of air especially for use in conjunction with an air extractor hood typically found in commercial food premises. The filter element (17) functions as a pre-filter and is therefore disposed adjacent or prior to a filter element (15) disposed in an airflow passage or across an aperture (14) disposed in an airflow passage. The pre-filter is disposable and is removably coupled via an attachment (20) to the filter element.</p> |
