## Features

- MATERIAL RELIABILITY: MS Reverse Osmosis (RO) membranes are made from 100% food-grade Thin Film Composite (TFC) material for ultimate purification performance with high permeate flow, tested by an independent third-party to meet NSF/ANSI 58 standards.
- HIGH REJECTION: 100 GPD RO membrane with a high 97% stabilized salt rejection rate. Hundreds of impurities are reduced by over 99% through the 0.0001-micron TFC membrane layer, including heavy metals (fluoride, calcium, magnesium, lead, colloids, chromium, and nitrates), organic materials, and harmful minerals, including other soluble salts found in water resources.
- UNIVERSAL MEMBRANE SIZE: Industry-standard element size 11.75 x 1.75-inch, designed to fit in standard 1812/2012 residential-style RO membrane housings utilizing a 2-inch internal diameter. Suitable for most Home Reverse Osmosis Water Filtration system and Maple Syrup filter systems.
- WIDE COMPATIBILITY: Reverse osmosis water filter replacement for standard membranes including but not limited to Dow Filmtec TW30-1812-100, AXEON TF-1812-100, Desal TFM-100, FLTMEME100, FS TFC TFC-2012-100, MC1.
- LONG-LIFE: The membrane element, shipped dry in an original sealed package, has a life expectancy between 24 to 36 months, based on average feedwater quality, temperature, and incoming water pressure.
- Tips: Recommend work pressure is 100 psi when using this product in a Maple Syrup reverse osmosis system. And we suggest heating and maintaining the raw sap at 104°F(40°C) to prevent clog on the membrane while keeping it under 113°F(45°C) to avoid damage to the membrane due to over-high temperature.

## Questions & Answers

**Q: Will this work for the aquatic life buddie?**
A: Yes it is still working well for my aquatic life ro buddie.

**Q: Will this work with hydro logic stealth ro200?**
A: Yes,our 100GPD-2012 size membrane is perfectly compatible with Hydro-logic's Stealth 200 Reverse Osmosis System.

**Q: Do any of your ro membranes fit the ao smith ao-us-ro-mb-4000**
A: I am unfamiliar with the system you were referring. However I can offer you this. This is the standard in filtration systems as I know it. If the membrane meaning the RO membrane can fit in a housing that is designed for it then usually that means it will work. So an example would be if you had a 10 inch long 2 1/2 inch diameter housing for a membrane you would roughly need a 10 inch long  2 1/2 inch wide membrane lol. Something helpful for the future as well. Whenever I purchase anything I keep the instruction manual for it in the same place for everything I own. That way if I have a question I can simply go to my “library” and find my answer lol.

**Q: Will this work with an ultima vii system?**
A: Your system makes 24gpd, The membrane filter your asking about makes 50gpd. You can upgrade your system to 50gpd by making some changes to the flow restrictor.
Go to utube and view numerous videos on RO systmes. The filter will work only after some changes to your system.
