Pearl Water 100 GPD RO Membrane Ultra (Pack of 5) – Reliable High-TDS Purification, Bulk-Ready
If your RO water purifier is producing slow, low-quality, or bad-tasting water, the membrane is usually the first component to check. The Pearl Water 100 GPD RO Membrane Ultra (Pack of 5) from Pearl Water Technologies is designed as a direct, dependable replacement for domestic RO systems that need to handle water with high TDS levels — up to 2000 PPM — and comes in a 5-piece pack built for households and facilities managing multiple purifiers or planning ahead for years of replacements.
What This Product Is
This is a 12-inch, 2-inch diameter TFC (Thin Film Composite) RO membrane, sold as a pack of five. It carries a 20 LPH (litres per hour) flow rate, translating to a 100 GPD (gallons per day) rated capacity, and filters at a pore size of 0.0005 micron — fine enough to reject dissolved salts, heavy metals, bacteria, and most dissolved solids from tap or borewell water. It's built with a food-grade housing and an anti-bacterial membrane sheet, and is manufactured in India under Pearl Water Technologies' quality standards.
How an RO Membrane Works
At the core of every RO purifier is the membrane. Source water is pushed under pressure against a semi-permeable membrane surface. Pure water molecules pass through the microscopic pores, while dissolved salts, contaminants, and larger molecules are blocked and flushed out as reject water. This is why an RO membrane is the single most important component determining your purifier's output quality and TDS reduction.
Why Choose a 20 LPH / 100 GPD Membrane
A 20 LPH rating means the membrane is engineered to process a higher volume of water per hour compared to lower-rated membranes, which matters when your input water has a high TDS level. Membranes rated for high TDS input (up to 2000 PPM here) are built with a tighter TFC layer that can consistently reject dissolved salts even from harder source water — common in many parts of India where borewell or municipal water carries elevated TDS.
Why Pack of 5 Offers Better Value
Buying a pack of five membranes is a practical decision for households and facilities that use RO water heavily:
Ideal for institutions and offices – Suits schools, clinics, restaurants, and small businesses running multiple RO purifiers.
Years of stock in one order – Five membranes can cover a single purifier's replacements for several years, or serve multiple units at once.
Best cost per unit – Larger pack sizes generally bring the lowest per-membrane cost compared to buying singly.
Minimal reordering – Reduces the frequency of placing new orders and tracking delivery timelines for a recurring wear item.
Consistent quality across units – Using the same membrane specification across all your purifiers keeps performance and maintenance predictable.
Water Quality, Performance, and Durability
With a total service life of 8500 litres per membrane, this membrane is built for sustained daily use in an average household or commercial setting. Its anti-bacterial membrane sheet helps limit microbial growth on the membrane surface, supporting more consistent purification performance over its lifespan. The food-grade housing ensures the material in contact with your drinking water meets safety expectations for domestic and small-commercial use.
Applications
This membrane works well in homes, apartments, offices, restaurants, clinics, schools, and small businesses. The pack of 5 format is particularly suited to facilities managing several purifier units or planning a long-term maintenance schedule.
Maintenance Tips
Rinse each membrane housing before installation, ensure correct O-ring seating to prevent leaks, and monitor your purifier's TDS output periodically. Replacing sediment and carbon pre-filters on schedule extends the membrane's usable life, since unfiltered particles are one of the most common causes of premature membrane fouling.
Buying Confidence
Every Pearl Water 100 GPD RO Membrane Ultra (Pack of 5) ships with a 1-year warranty and a 10-day replacement policy, giving you assurance on quality and fit. It is designed to be compatible with all standard domestic RO water purifier systems using the common 12-inch, 2-inch housing format, and installation is straightforward enough for DIY setup without needing a technician visit in most cases.
For multi-purifier households, offices, schools, or businesses dealing with hard or high-TDS water, this pack of 5 is a cost-effective way to stay stocked for years — restoring purification performance across multiple units without repeated ordering.

Is this membrane compatible with my RO purifier? Yes — the Pearl Water 100 GPD RO Membrane Ultra fits all standard domestic RO water purifier systems that use the common 12-inch length, 2-inch diameter membrane housing. This sizing is used across the vast majority of domestic RO units sold in India.
Installation guidance:
Turn off the RO purifier and close the water inlet valve.
Open the housing and remove the old membrane.
Rinse the new membrane briefly under clean water before fitting.
Insert the membrane into the housing, ensuring the O-rings sit correctly to prevent leaks.
Close the housing, reopen the inlet valve, and power on the unit.
Run the purifier for a few minutes and discard the first batch of water before regular use.
Store the remaining membranes in a cool, dry place, in their original packaging, until needed.
For multi-unit setups, label each installed membrane with its fitting date to track replacement schedules per purifier.
If you're unsure about your purifier's housing size, check your existing membrane's markings or consult your purifier's manual before ordering.
What is reverse osmosis? Reverse osmosis (RO) is a water purification process that pushes water through a semi-permeable membrane under pressure, separating pure water from dissolved salts and contaminants.
Step-by-step process:
Water enters the system – Raw tap or borewell water is drawn into the purifier and passes through pre-filters (sediment and carbon) to remove larger particles and chlorine.
Pressure is applied – A pump pushes the pre-filtered water against the RO membrane at a specific pressure.
Membrane separation occurs – The 0.0005 micron TFC membrane allows only water molecules to pass through, while dissolved salts, heavy metals, and microorganisms are blocked.
Purified water is collected – The filtered water passes into a storage tank, ready for drinking.
Rejected water is flushed out – The concentrated impurities that didn't pass through the membrane are carried away as reject/waste water.
Post-filtration (in most purifiers) – Some systems pass the RO water through a final carbon or mineral cartridge before it reaches the tap, improving taste.
Health: Reduces dissolved salts, heavy metals, and microbial contamination, supporting safer drinking water.
Water Taste: Lowering excess TDS and dissolved impurities typically results in noticeably better-tasting water.
RO Efficiency: A properly functioning membrane keeps flow rate and purification consistent, so the rest of your purifier's system (pump, tank, filters) works as intended.
Long-Term Savings: Buying five membranes together brings down the cost per unit and reduces the hassle of repeat orders across multiple purifiers or years of use.
High Purification: 0.0005 micron filtration combined with 2000 PPM TDS handling addresses both hardness and dissolved impurity concerns in one component.
Easy Maintenance: DIY-friendly installation and a ready supply of spare membranes mean you don't need to schedule a technician visit or wait on repeated deliveries.
Who should buy this product? This pack is best suited for multi-purifier households, offices, schools, clinics, restaurants, and small businesses that want to stock up on replacements in bulk, or for anyone in a high-TDS water area who wants years of membrane supply in one order.
When to replace the membrane: Most domestic RO membranes need replacement every 12–24 months, depending on source water quality and usage. Households with high-TDS input water often see shorter membrane life and should monitor performance more closely.
Signs replacement is needed:
Noticeably slower water flow from the purifier
Rising TDS reading in the purified water
Unusual taste or odour in the filtered water
The purifier running longer than usual to fill the storage tank
It has been more than a year since the last membrane change
Expected lifespan: Each membrane is rated for a total service life of 8500 litres, translating to roughly 12–18 months of typical household use, depending on source water TDS and daily consumption. With five membranes in the pack, this purchase can realistically cover 5+ years of replacements for a single purifier, or serve multiple units in parallel — making it a practical bulk buy for larger households or facilities.
Required fields are marked *
