Air filter sponge cuttable 300x400mm Polini

Cuttable air filter sponge 300x400mm. These Polini air filters are made of polyurethane and reticulated polyester, which gives them great efficiency. The filter is made with two layers of foam, the finer one in blue (60 PPI porosity) and a black one with lower porosity (30 PPI). This design allows the finer layer to filter the smallest particles, not coming into contact with the larger particles, thus increasing the filter's lifespan.

Thanks to the wavy design on the exterior, the filter achieves greater air intake. If you want even greater dust retention capacity, you can impregnate the filter with foam filter oil. Another feature of the air filter is the ability to wash and reuse it. Due to its cuttable nature, it can be adapted to many filter box models.
