The SANIFRIGOFILTER is a filter that exploits the principle of photocatalysis and which is offered in the range of Autoclima products to be combined with the majority of Frosty evaporators available in the catalog. Photocatalysis is a natural phenomenon in which an active substance, said photocatalyst, present on the filter surface, through the action of light LED placed on the sides, converts light energy into electrons; by means of the reaction with water present in the air humidity that flow through the filter, it causes a decomposition of the organic and inorganic pollutants present in the air stream and thus it reduces the bacterial charge present therein, SANIFRIGOFILTER is not a mechanical filter: it doesn't need any specific clean or maintenance.
