Greenworks and 3M have worked together to develop the AP2-G range, building on its established AP2 product. The AP2-G system utilises the same head as the earlier AP2 range, but the filter has been miniaturised. 3M claims a 53 per cent reduction in plastic content in comparison with the former AP2, plus the dramatically reduced filter size means less packaging. Performance, however, hasn’t suffered. To achieve this, 3M developed an advanced carbon filter technology, which introduces a number of enhancements to achieve a higher active media content in a smaller size. The filter comprises an engineered media featuring multiple powdered materials combined with a unique binding matrix. The filter is also available with an optional scale inhibitor.
