Important Notice


1. This product is the China version. Please make sure to check whether it is compatible with your local plumbing system and connection standards before purchasing. If you are unsure, we recommend consulting a local plumber before installation.

2. Why does the product label show 5 mu00b3/h (5 T/h) flow rate?

The 5 mu00b3/h rating printed on the unit, packaging, and manual is based on the Q/DBKJ 016-2023 Front Filter standard, meaning the filter can still achieve this flow after a total processed volume of 6,500 tons.

3. Why is 8 T/h shown on the product page? According to testing by the Nanjing Institute of Product Quality Supervision, under 0.39 MPa inlet pressure with a 1-inch tube, the initial flow rate reaches up to 8 T/h. Test report No.: NZJ(2025)FR01-02871Z.
