The Qiteng UF-4+1 Quick-Change 5-Stage Water Filter is a wall-mounted system with 4 vertical cartridges plus 1 horizontal T33 post-carbon cartridge, forming a complete 5-stage filtration chain: PP (melt-blown) + CTO (carbon block) + PP (melt-blown) + UF (ultrafiltration membrane) + T33 (horizontal post-carbon). The progressive 5-stage design with dual PP protection delivers more stable purification; the UF membrane (0.01–0.1μm) retains beneficial minerals and, depending on the water source, can produce direct-drinking water. The horizontally-mounted T33 stage on top of the unit further polishes residual taste and odor. The quick-change bayonet cartridges can be swapped in seconds without tools — ideal for home kitchens, commercial kitchens, bubble tea & coffee shops, and ice-making equipment.
