RO Membrane Price in India: A Complete Guide for Buyers

Introduction: Why RO Membrane Price Matters

In the water purifier industry, RO membranes are the backbone of the reverse osmosis process. Whether you are a home user or a commercial buyer, understanding the RO membrane price and the factors influencing it can help you make a smarter, long-term purchase. Prices for RO membranes vary widely depending on brand, filtration capacity, type, and build quality.

This blog will help you understand what drives RO membrane prices in India, compare top-selling membranes in 2025, and guide you toward buying the right product based on your needs.

What Is an RO Membrane?

An RO (Reverse Osmosis) membrane is a semi-permeable barrier that removes impurities such as dissolved salts, bacteria, heavy metals, and toxins from water. It is the most critical part of an RO water purifier system, acting as the main filter. The membrane uses pressure to push water through microscopic pores, separating contaminants from clean water.

Depending on usage, TDS level, and maintenance, the lifespan of a membrane generally ranges between 12 to 24 months.

Factors That Affect RO Membrane Price

RO membrane prices are not arbitrary. They are influenced by several key factors:

1. Brand and Manufacturer

Top brands often use higher-grade materials and more advanced filtration technologies, which justifies a premium price. For example, Lexpure and Osmotech are known for consistent quality and performance.

2. GPD Capacity

GPD stands for Gallons Per Day. The higher the GPD, the more water the membrane can purify. Domestic membranes usually range between 80–150 GPD, and higher capacity models generally cost more.

3. Build Material and Certifications

Membranes built using polypropylene or high-density polymers are more durable and efficient. If a membrane is NSF-certified or BIS-approved, it may cost more due to regulatory standards.

4. Type of Membrane

There are different RO membrane types—like Thin Film Composite (TFC) and Cellulose Acetate membranes—each with distinct pricing and filtration capabilities.

5. TDS Handling Capability

Membranes designed for high TDS water (above 1500 ppm) cost more than those designed for low or medium TDS levels due to added layer thickness and density.
