What to know before buying
Listing details to confirm
The listing calls the system seven-stage, while its filtration description identifies a 3-in-1 filter containing an RO membrane, carbon block and PP cotton. It also describes four temperature options and a 45–95°C range adjustable in 5°C increments, which does not clearly align with four distinct settings. The display does not report mineral values. Confirm the selected listing's exact filter and temperature details before purchase.
