The correct functioning of HEPA filters is normally tested at the time of installation, as well as part of the routine maintenance programme. It is normally recommended that HEPA filters are checked at 14 month intervals or less, or immediately after filter changing. Where high efficiency filters are fitted, it is vital that the filter housing/sealing device does not allow particulate material to pass and thereby compromise the clean room environment that is being served. Testing is necessary since HEPA filters can become partially or totally blocked, rendering the filter of little value.
