    Pentek CBR2-10 # 155268 CBR210 Carbon Block Water Filter CMR-10 Compatible With Culligan / Ametek / US Filter / Plymouth / Kleen Plus / American Plumber / Bruner and Many Other Brands. Carbon Block With Lead Reduction Half Micron Water Filter. (Green End Caps) 9 3/4" long X 2 7/8" diameter. 12 per case, sold individually. Ametek # 155268 Replaces Ametek CMR-10. The CBR2 series are multimedia cartridges designed to perform several functions. CBR2 Series cartridges are manufactured using a patented process and combine powdered activated carbon with a specially designed media for lead reduction. In addition to lead reduction, the unique formation of the carbon block enables it to reduce Cryptosporidium and Giardia cysts and fine sediment particles down to 0.5 microns. As with our standard CBC Series carbon block, both the CBR2-10 and CBR2-10R are more effective at reducing levels of chlorine, and certain VOC's than granular activated carbon cartridges. The Polypropylene outer wrap helps reduce coarse sediment particles, effectively extending the useful life of the cartridge. Order a case and save even more.Learn More

    TDS Meter - Tester. The Only Way To Know If Your Reverse Osmosis RO Membrane Is Performing Correctly - Tests for TDS - Total Dissolved Solids. A Must For All RO System Owners. Compare Incoming Feed Water To Treated Water - Replace Membrane If Less Than 80% of TDS Is Being Removed - The lower the TDS level in the water, the more efficiently your body's cells actually get hydrated by the water that you drink. The higher the TDS levels in the water, the greater the probability of harmful contaminants that can pose health risks or hinder the absorption of water molecules on the cellular level. Simple to use for Reverse Osmosis membrane monitoring. We really like this tester and think that anyone who wants to know about the quality of their water should have one of these TDS Meter Testers to monitor their RO membrane. Learn More

Easy TDS Membrane Performence Calculator
See If It is Time To Replace Your Membrane

Simply enter your Feed Water TDS and RO Water TDS into the boxes above and click "Submit". The percentage of TDS (total disolved solids) rejection will be displayed. We normally recommend membrane replacement once you drop below 75%. This may vary in areas with high TDS in the feed water.   Let the tap water and reverse osmosis water run for a few seconds before drawing your sample.

See our selection of TDS meters under Water Tests.  Knowing the rejection rate is the only wat to know if it is time to replace your reverse osmosis membrane.

Be sure to check our Parts Department for important parts such as TDS Testers For Reverse Osmosis Membranes, Replacement Tanks, O-rings , Filter Housing Wrenches, Faucets, Pumps, Fittings, UV Systems and more parts for your reverse osmosis pure water filtration system.   View maintenance and servicing tips online at our Installation & Trouble shooting Guide.
