Inquiry about Faucet-Mounted Ceramic Water Filter

I am developing a water filtration brand for the South African market and am interested in your faucet-mounted ceramic water filter. I would like to test the product before placing a larger order. I need 2–5 branded samples with our logo printed on the product and branded packaging if possible. Please advise the MOQ and setup cost for logo printing. I also require pricing for replacement cartridges in quantities of 10, 20, and 50 units. Please provide the exact cartridge model, filtration media, rated filtration capacity in litres, recommended replacement interval, and any available cartridge options with different capacities. I prefer a cartridge with the longest practical lifespan while maintaining good filtration performance and affordable replacement cost. Additionally, please provide product details including the exact model number, dimensions, weight, flow rate, compatible faucet sizes, whether adapters are included, and available certifications and test reports.
