GE FX18M Video Transcript

Hey everyone, Aquaman here with FilterDoctor.com. Today weíre looking at the genuine GE FX18M. This is a proprietary reverse osmosis membrane designed specifically for certain GE RO systems. This membrane fits in all GE RO systems beginning with the part number PNRV18; regardless of the last two digits. Your part number might end in BB or WH or Z; this membrane fits in all of those GE RO systems. Now, GEís internal testing has certified this membrane to do exactly what you expect it to do; remove 95 plus percent of total dissolved solids. Now, dissolved solids are nearly everything in your water, some of it is perfectly harmless and some of it is really nasty, which is why you have an RO membrane removing a vast array of contaminants that are considered dissolved solids. Now, there are two ways to know when to change your membrane. You could go by the rule of thumb, and at least change it once every two years, or you could be a bit more scientific about it and own a TDS meter to measure the total dissolved solids in your reverse osmosis water. What youíre looking for is a minimum 75% reduction in total dissolved solids, as compared to your unfiltered water. If your RO membrane isnít removing at least 75% of the TDS, itís exhausted and it needs to be replaced. Now, GE has been really thoughtful when they put together their package, and theyíve provided an additional part. Iím sure itís difficult to see this on camera, but this is a flow control or flow restrictor and a protective cone screen. GE has likely provided these, because these parts are exposed to water that has minerals in it and those minerals precipitate and clog these components. So be sure to change your flow restrictor and your protective cone screen when you change the membrane. Again, this is the genuine GE FX18M, and Iím your host Aquaman with FilterDoctor.com. Thanks for watching.
