no but you should buy a proper Dow filmtec. they are the industry leaders in membranes and very high quality. it will say Dow filmtec on it.

it should be your sediment filter, if your carbon filter is plugging up first then you are not running a low enough micron sediment filter.

I run a 5 micron, then a 1 micron, then carbon (I run two carbon due to the volume of water I am pushing through) the reason for the 5 micron filter is to catch the free algae in the water and prevent it from plugging the 1 micron filter.

also for you people buying pre filters make sure they are 1 micron absolute, not 1 micron nominal. the latter is an average for the filter and they let particles bigger than 1 micron through and this could be plugging up carbon filters early.
