Compact, spherical water purifier with a replacement目安 of approximately 3 months and a switch for different water flow options. - Model: CP3 - Size: Height 8cm, Diameter 7cm - Replacement目安: Approximately 3 months - Features: Water purification, switch for water flow options - Design: Compact, spherical design Unfortunately, I couldn't install it because my faucet type was different. I previously bought a similar product from the same company (not the swivel type), which included attachments that allowed it to be installed on most faucets, so I didn't check carefully before purchasing. The product description and photos don't make this very clear, and depending on the faucet type, installation may not be possible, or a separately sold attachment may be required, so be careful. The appearance is not much different from the one I bought before, so I think the water purification performance is good. Even after the water purifier's lifespan is over, it's very, very convenient as a shower! Thank you for viewing.
