COMPATIBILITY & APPLICATIONS
System Compatibility
This 35 GPD membrane is designed as a direct replacement for Hydrotech HT and HFT series reverse osmosis systems. The yellow and purple band quickly identifies the correct capacity rating during installation and maintenance. Suitable for residential point-of-use drinking water systems, under-sink RO installations, and light commercial applications where daily water demand does not exceed 35 gallons. The thin film composite construction provides reliable contaminant reduction including dissolved solids, heavy metals, and microorganisms. Compatible with standard 1.8" x 12" membrane housings used across Hydrotech and many cross-compatible residential RO platforms.
💧 Replace your RO membrane every 24-36 months depending on feed water quality and daily usage volume. If you notice a significant drop in production rate or TDS creep in your permeate water, it's time for a new membrane regardless of age.
