Three filters in one – a 3-layer filter consisting of NanoProtect HEPA, activated carbon and pre-filter ensures that you are protected from bacteria, pollen, dust, PM 2.5, pet hair and gases. DURABLE MATERIALS FOR CONSTANT PERFORMANCE - Made from durable and high-quality materials, our filters offer extended life and consistent performance. This reduces the need for frequent filter changes and ensures that your air purifier always delivers optimal results, reducing long-term costs. The Supremery filter was designed together with the device. This guarantees the perfect fit, which ensures continuous smooth operation of the device. Regular cleaning of the pre-filter – for optimal filter performance, the pre-filter should be vacuumed regularly. NanoProtect HEPA technology not only detects harmful substances, it also attracts them via a special electrostatic charge. This cleans the air even faster than with a medical HEPA H13 filter.
