Description
250 GPD highest-output residential RO membrane
2012 TFC/TW membrane for compatible countertop and under-sink reverse-osmosis systems
This 250 GPD thin-film composite reverse-osmosis membrane is the highest-output residential membrane in the current MyAquaFilter/MyWaterClub lineup. It is designed for compatible systems where faster purified-water production is the priority, including tankless countertop RO and higher-demand under-sink installations.

Application
Maximum residential output for faster tankless and high-use RO systems
A 250 GPD membrane produces water significantly faster than 100 or 150 GPD residential membranes. It is a strong choice for compatible countertop systems without a storage tank, tankless under-sink RO, and households that want faster recovery and higher daily drinking-water production.
Under-sink RO
Higher Daily Demand
Suitable for compatible tank-based or tankless under-sink systems designed around a 250 GPD membrane and matching drain-flow restrictor.
How it works
Thin-film composite membrane for dissolved-solids reduction
Reverse osmosis uses water pressure to move feed water across a semipermeable TFC membrane. The membrane helps reduce dissolved salts, minerals, metals, nitrate, fluoride, and other membrane-rejectable substances while purified water passes to the product-water side.
Dissolved Solids
Helps reduce overall TDS and dissolved mineral content.
Fluoride
Helps reduce fluoride ions under suitable operating conditions.
Nitrate / Nitrite
Helps reduce nitrate and nitrite in the feed water.
Selected Metals
Helps reduce dissolved metals such as lead, arsenic, mercury, chromium, and copper.
Dissolved Minerals
Helps reduce calcium, magnesium, sodium, and other dissolved salts.
High-Output Residential Format
Ships as a standard 2012-size residential membrane.
What 250 GPD means
Rated output is approximately 10.4 gallons per hour under ideal test conditions
GPD means gallons per day. A 250 GPD membrane is rated for approximately 10.4 gallons per hour if operated continuously under standardized test conditions. Actual household production is normally lower because water pressure, temperature, feed-water TDS, membrane condition, and system design vary.
250 gallons per day under standardized test conditions.
Typically lower than the rated value, especially with colder water, lower pressure, or higher source-water TDS.
GPD describes membrane production capacity, not guaranteed household output. The membrane, flow restrictor, pressure, temperature, and system configuration all affect actual production.
Compatibility

Why choose 250 GPD?
Best suited to applications where water-production speed matters most
✓
Countertop systems without storage tanks
Higher membrane capacity can shorten fill time when system pressure and restrictor sizing are appropriate.

✓
Tankless under-sink RO
Higher rated membrane output can better support applications that depend on direct production rather than tank storage.

Maintenance
Replace based on age, production rate, and measured rejection
Approximately 2–3 years under normal residential conditions with proper prefiltration.
Consider replacement when purified-water production slows significantly or measured TDS rejection declines.
Installation
Protect the membrane and flush it before evaluating performance
1
Shut Off and Depressurize
Turn off the feed water and release system pressure before opening the membrane housing.
2
Install and Fully Seat
Insert the membrane according to the housing design and make sure the sealing end is fully seated.
3
Check Prefilters and Restrictor
Confirm that sediment and carbon prefilters are serviceable and that the drain-flow restrictor matches the 250 GPD membrane.
4
Flush Before Use
Run and discard the initial product water after installation, then allow the system to stabilize before relying on TDS readings.
Before purchase
Good to know
!
250 GPD is a rated value
Actual household output is normally lower and depends strongly on feed pressure, temperature, and source-water TDS.

!
Higher GPD is not automatically a drop-in upgrade
A 250 GPD membrane may fit an existing housing, but the flow restrictor and overall system configuration must also match the higher capacity.

2012 diameter should be confirmed
This product ships as a 2.0″ × 12″ 2012 membrane. Confirm that a third-party housing accepts this diameter before ordering.

Chlorine protection is important
TFC membranes require effective carbon pretreatment to help protect the membrane from oxidant exposure.
