<p>Various types of filters are known. However, regardless of the size of the filter, there may be problems associated with storing filters prior to use and also with their disposal after use. Described herein is a disposable filter (10) including a flexible casing (12, 14) and at least one filter element (16, 18, 20). The flexible casing (12, 14) and filter elements (16, 18, 20) are expandable from a substantially flat form for use and are collapsible to a substantially flat form after use for disposal.</p> |
