RO Membrane Price in India: 75 GPD, 80 GPD and 100 GPD Buying Guide
An RO membrane is one of the most important components of a domestic reverse osmosis water purifier. It helps reduce dissolved impurities from water and supports the purification process. When the membrane becomes worn out, damaged or less effective, replacing it may help restore the purifier’s performance.
If you are searching for the RO membrane price in India, it is important to understand that the cost depends on several factors, including membrane capacity, brand, compatibility, product quality and seller pricing. Popular options include 75 GPD, 80 GPD and 100 GPD membranes, but the right choice depends on your purifier’s specifications.
For homeowners, RO technicians, repair professionals and spare-parts dealers, understanding these differences can make purchasing easier. This guide explains membrane capacities, price factors, replacement signs and the key points to check before buying.
What Is an RO Membrane?
An RO membrane is a semi-permeable component used in reverse osmosis water purification systems. Water passes through the membrane under pressure, helping separate many dissolved substances from the water.
The membrane works alongside other purifier components, such as sediment filters, carbon filters, pumps and flow restrictors. Each component performs a different role in the purification process.
A membrane’s performance can be affected by incoming water quality, operating pressure, maintenance, pretreatment and the condition of other components.
What Affects RO Membrane Price?
There is no single price for every domestic RO membrane. Before comparing products, consider the following factors.
1. Membrane Capacity
GPD stands for gallons per day and indicates a membrane’s rated production capacity under specified test conditions. A 75 GPD membrane and a 100 GPD membrane may have different rated outputs, but actual performance depends on operating conditions.
2. Brand and Manufacturing Quality
Different manufacturers may use different materials, manufacturing processes and quality-control standards. These differences can affect pricing and product performance.
3. Compatibility With Your RO Purifier
A membrane must match the purifier’s membrane housing, fittings and operating requirements. Buying a membrane simply because it has a lower price can lead to compatibility problems.
4. Water Quality and Operating Conditions
High dissolved solids, inadequate pressure, scaling and fouling can affect membrane performance. A suitable pretreatment system and regular maintenance can help protect the membrane.
5. Quantity and Supplier Pricing
Individual buyers, RO technicians and dealers may have different purchasing needs. Wholesale orders can have different price structures from single-piece purchases. Always check the seller’s quantity-based pricing and applicable terms.
75 GPD vs 80 GPD vs 100 GPD RO Membrane
Compare the rated capacity and compatibility before choosing a replacement.
| Membrane type | Key consideration | Suitable buying approach |
|---|---|---|
| 75 GPD RO membrane | Common option for compatible domestic purifiers | Match the existing membrane specifications |
| 80 GPD RO membrane | Alternative capacity available for some purifier models | Confirm the manufacturer’s recommended capacity |
| 100 GPD RO membrane | Higher rated capacity under specified test conditions | Check pump, housing and system compatibility |
Important: A higher GPD rating does not automatically mean a membrane will work better in every purifier. Check the equipment manufacturer’s specifications before purchasing.
How Much Does an RO Membrane Cost?
The RO membrane price varies by brand, capacity, quality, seller and order quantity. Prices can also change over time, so buyers should check current listings rather than relying on an outdated estimate.
When comparing prices, review:
Membrane capacity and model details.
Brand and product specifications.
Compatibility with the existing purifier.
Warranty or replacement terms, if offered.
Shipping charges and minimum order quantities.
Wholesale rates for bulk purchases.

Signs That Your RO Membrane May Need Replacement
A change in purifier performance can indicate a membrane problem, but it does not always mean the membrane needs replacing. Other filters, pumps and components may also be responsible.
Common signs to investigate include:
Reduced Water Production
If the purifier produces less water than usual, possible causes include low inlet pressure, clogged filters, a faulty pump or membrane fouling.
Changes in TDS Readings
A noticeable change in the purified water’s TDS reading may indicate reduced membrane rejection or another system issue. Check the source-water and purified-water readings with a suitable meter.
Unusual Taste or Water Quality Changes
A change in taste or water quality should not be ignored. Inspect the purifier and arrange appropriate water testing when necessary rather than assuming the membrane is the only cause.
Frequent Purifier Performance Problems
Repeated issues may be linked to poor pretreatment, scaling, incorrect operating pressure or overdue maintenance. A qualified technician can help identify the underlying cause.
How to Choose the Right Domestic RO Membrane
Follow these steps before ordering a replacement.
Check the existing membrane: Note its GPD rating, model and manufacturer information.
Confirm compatibility: Check the purifier manual or manufacturer’s specifications.
Inspect the system: Verify the condition of prefilters, pump pressure and membrane housing.
Compare product details: Review specifications, seller information and replacement terms.
Choose a reliable supplier: Purchase from a source that provides clear product information and supports your buying requirements.
These checks help reduce the risk of ordering an unsuitable membrane.
Tips to Maintain Your RO Membrane
Good maintenance can help support consistent purifier performance.
Replace sediment and carbon filters according to the manufacturer’s maintenance schedule.
Check the purifier’s inlet pressure and pump performance.
Follow the recommended pretreatment procedure where applicable.
Monitor water production and TDS rejection over time.
Inspect for leakage, scaling and other system problems.
Arrange professional servicing if performance drops unexpectedly.
Membrane lifespan varies according to feed-water quality, usage and maintenance. Avoid following a fixed replacement interval without considering the manufacturer’s recommendations and actual system condition.

Frequently Asked Questions
1. What is the RO membrane price in India?
The price varies according to capacity, brand, quality, compatibility and supplier. Check current product listings for the latest available price.
2. What is the difference between a 75 GPD and 100 GPD membrane?
The main difference is their rated production capacity under specified test conditions. Actual output depends on water pressure, temperature, feed-water quality and the purifier’s design.
3. Can I replace a 75 GPD membrane with a 100 GPD membrane?
Not in every purifier. Confirm compatibility with the purifier manufacturer or a qualified technician before changing the rated capacity.
4. How do I know if my RO membrane needs replacement?
Reduced water production or changes in TDS rejection may indicate a problem. Check the filters, pressure, pump and other components before deciding that the membrane needs replacement.
5. Where can I find domestic RO membranes online?
You can explore the Domestic RO Membrane category on RO Service & Sales and review the available product specifications.
