This is a used item purchased approximately 10 years ago. Water stains are noticeable on the main unit. The box is also in poor condition. Multi-Pure Shower Filter Crystal Quartz SFFH This is a complete set. It is used and second-hand. A cartridge is included, but it is used and past its replacement date, so you will need to purchase a new one yourself. Also included are the dedicated adapters, but it is unclear if they will fit your current shower, so please judge for yourself. Not all adapters are included. As a precaution, I will include an adapter set that came with a recently purchased shower head. (I was able to install it without an adapter.) According to the instruction manual, it may be possible to connect directly without an adapter for products from manufacturers such as SAN-EI, INAX, KAKUDAI, MYM, and HVS. Please only purchase if you understand the above. The instruction manual, dedicated box, and residual chlorine test paper are included. The shower will purify water, and by removing chlorine, the hot water will become softer and improve hair quality. - Filter material: KDF alloy, natural quartz ore - Size: Width 70 x Height 225 mm - Total filtration capacity: 100,000 L (25,000 gal) - Substances removed: Residual chlorine Weight: 670g (including cartridge) Manufacturer model number: SFFH For the cartridge, search on Amazon for "Multi-Pure Water Purifying Shower Replacement Cartridge for SFFH SFFI" to find it.
