China Factory Direct: 100 GPD RO Membrane for Home & Commercial Water Purification
The 100 GPD RO Membrane is a high-performance reverse osmosis solution designed for residential, commercial, and laboratory water purification systems. Engineered with NSF-certified materials, this membrane features a 0.0001μm filtration precision – fine enough to block bacteria, viruses, heavy metals, and dissolved solids, ensuring safe drinking water for homes, restaurants, and labs.
Compatible with most under-sink and countertop RO systems (e.g., APEC, iSpring, and Aquasure models), it operates at a standard pressure range (50–80 psi) and delivers a steady 100 gallons per day – ideal for small to medium households (2–4 people) or commercial spaces like cafes and dental clinics.
Unlike "fake membranes" with vacuum-sealed designs (which degrade performance over time), our non-vacuum dry film maintains long-term stability, with a recommended replacement cycle of 2–3 years (depending on water quality and pre-filtration efficiency).

Features: Why Choose Our 100 GPD RO Membrane?
0.0001μm Ultra-Fine Filtration
The membrane's microscopic pores (0.0001μm) block 99.9% of contaminants, including bacteria (0.2μm), viruses (0.02μm), lead (0.001μm), and nitrates, ensuring water purity for drinking, cooking, and lab experiments.
99% Desalination Rate (High-Glue Joint Design)
A reinforced glue joint diaphragm and O-ring seal prevent leakage, maintaining a stable 99% desalination rate even after 2 years of use. Resistant to chemical and biological degradation, it outperforms standard membranes in hard water areas.
Non-Vacuum Dry Film (No "Fake Membrane" Risk)
Our original dry film design avoids vacuum sealing (common in low-quality "fake membranes"), which can cause pore blockage and reduced flow over time. This ensures consistent performance from installation to replacement.
RO Membrane Application
- Home Drinking Water
- Aquariums Water

- Restaurant Water
- Under Sink Water
FAQ
What's the difference between 100 GPD and 200 GPD RO membranes?
A: GPD (gallons per day) refers to water production capacity. A 100 GPD membrane is ideal for small households (2–4 people) or low-demand commercial use (e.g., cafes), while 200 GPD suits larger families or high-use spaces (e.g., restaurants).
How to know when to replace the RO membrane?
A: Signs of replacement needed:
- Reduced water flow (e.g., takes 10+ minutes to fill a glass).
- Increased TDS (total dissolved solids) in purified water (test with a TDS meter).
- Foul taste/odor (indicates membrane degradation).
- Pro tip: Pair with our PP melt blown pre-filters to extend membrane life by 30%!
Do you export to Europe? What certifications are required?
A: Yes! We export to 25+ countries, including the US, Europe, and Australia. Our membranes are NSF-certified (US), CE-compliant (EU), and ISO 9001-2015 certified, ensuring smooth customs clearance.
Can I use this membrane with my existing RO system?
A: Most likely! Our 100 GPD membrane is compatible with popular RO systems like APEC, iSpring, and Aquasure. If you have a non-standard housing, contact us for custom size options (minimum order 100 units).
