• ‌Important Use Notes & Faucet Fit: This under-sink system does not reduce TDS and is designed for municipal tap water and cold water only (not for well water or hot water). It fits faucets with 1/2" or 3/8" female NPT threads. If you need to connect to a quick-connect faucet, compatible connection fittings can be provided upon request.
• Replacement Filter Models: For TST-UF/TST-UF-B systems, replacement filters include WD-P1, WD-U2, and WD-C3 (search by these model names).
• Filtration & Taste Support: Built with 6 filtration layers, including an ultrafiltration membrane designed to help reduce impurities larger than 0.01 microns, along with common concerns such as chlorine, odor, and certain heavy metals, supporting better-tasting water for drinking and cooking.
• Easy DIY Installation: Connects directly to 3/8" or 1/2" home water pipes. Installation videos, instructions, and customer support are available to help with setup.
• Fast Flow & Filter Life Guidance: Designed to provide a steady flow rate of up to 1.59 GPM, filling an 8 oz cup in about 2.3 seconds under typical conditions. Typical filter-life guidance: PP filter 6–8 months, UF filter about 12 months, and CT filter 12–24 months (varies by local water conditions). Reduced housing changes may help lower plastic waste over time.
