<p>The invention concerns a microwave diffuser, for trays to. The invention concerns a regenerable air filtering system for control ling aeromicrobial growth, which enables the permanent removal and deacti vation of micro-organisms suspended in confined air spaces by having a lethal action on them. The system consists of an air filtering device composed of a filter element, which can be of a modular type, having a granular bed based on aluminosilicate metallized with one or more metal ions having an antibacte rial activity and non-toxic for the body, such as silver, zinc, copper or their mixtures, and a particle size ranging between 1 µm and 50 mm, preferably between 50 µm and 50 mm. The filter element may be combined with one or more pre-filter ele- ments based on chitosan and/or its functionalised derivatives, metallized with one or more ions having antimicrobial activity and non-toxic for the body. The device may also include separate means for forcing the air undergoing treat¬ ment through the device.</p> |
