Re-usable filters
Illustrated Guide to Ventilation (BG 2/2009), compiled by Kevin Pennycook and published by BSRIA in 2009, states: ‘In certain applications, non-disposable filters are preferable because of high contaminant concentrations. High dust-loads can require regular filter changes, or the use of a foam filter which can easily be removed and cleaned. Re-usable filters are often used in kitchens to trap grease and prevent it building up in ductwork. Metal filters are non-flammable, heat conducting and can act as flame-arresters. Mesh filters are coarse panel filters made of several layers of wire mesh that can be coated with oil to improve the dust collection and holding ability. Foam and metal mesh filters both work on the straining filtration principle, and tend to be classified as EU1 or EU2. Both types are cleaned in warm soapy water and re-coated with oil if required. The ability to re-use the filters means that they are often installed where normal fibre panel filters are unsuitable, such as in mesh filters above grilles in kitchens. Metal mesh filters are not oil-coated when installed in kitchen cooking extract systems.’
