The POSEION sediment filter is the suitable polypropylene replacement filter for the POSEION BT100 shower head and is supplied in a convenient 4-pack. It ensures that the filtering performance of your shower head is permanently maintained.The high-density polypropylene (PP) filter traps rust, sand, fine dust and undissolved deposits down to 5 microns before the water reaches your skin, scalp and hair. This reliably prevents impurities and residues from old pipework from passing through.For optimal results, the filter should be replaced every 4 to 6 months – or as soon as the water pressure noticeably decreases. A slight browning of a new filter is completely normal and indicates that it is working correctly.The replacement filter is designed to fit exclusively for the POSEION BT100, is easy to install and is recyclable. This technical product is not a cosmetic item. Manufactured in South Korea.
