IPW Industries Inc. - Reverse Osmosis Membrane Replacement Filter - 33001033 50 GPD RO Water Filter TFC - Under Sink Water Filtration System

Not much to say other than it's an authentic membrane filter replacement!(+): Price, price, price! You won't find a better price anywhere! This filter are almost 50% cheaper on Amazon than the local vendors.(-): NoneIt's recommended to replace this membrane once every 2 years or once every 2-3 carbon/sediment filter changes. Also, if you're an avid water drinker, make sure to the 50gpm membrane, not the 25gpm one.Highly recommended!

Reduces 300ppm hard city tap water to 30ppm purity which is OK! For regular drinking water Aquafina @ 1ppm still can't be beat but I use this RO purified water for cooking, coffee maker, ice cubes and for my dog. I replace my filters annually for proper operation. Good fitment and performance.

Feb 2017 to Feb 2018. It’s been a year and it still has approx. 98% reduction. I have an incoming TDS of 1120 from my terrible city water. After using it for a year it still puts out 22-24 TDS water. I’ll keep on using it and see if it lasts another year.

Did the job

Good fit

ok

Put the filter in a while ago, works fine

Exact replacement.

Out of the bag this 50 GPD RO Filter does not fit the 35 GPD Cullingan water tower, the white nipple diameter where the 2 lower O'Rings closest to the filter is to wide. No problem, you can simply replace it with the one from your old 35 GPD RO filter. The White nipple will unscrew, but it has reverse threads, simple unscrew it (clockwise, backwards from normal) and replace the 50 GPD with the 35 GPD. Problem solved. $78 instead of $150 for a new cullligan branded one, no brainer.

Same filters I always buy just at a better price

Will buy again.

great stuff

Ordered this Hydrotech membrane for my System 1230 to replace Part#41400006. Appears the two are identical in size and the replacement fits.Fast delivery. Excellent price.
