Amazing 30,000 gallon chlorine capacity and great chemical removal properties. Our most popular cartridge. (Formerly MatriKX +1.)
A free-flowing but very effective carbon block. A versatile and inexpensive filter that works anywhere carbon filtration is needed. A great reverse osmosis pre-filter.
High quality 0.5 micron carbon block drinking water filter. Rated for cyst removal and lead reduction, plus excellent taste/odor and chemical reduction properties. Not recommended for use in reverse osmosis units.
A limited-capacity cartridge designed to remove all mineral content from water, usually as a final polish for water that has been treated by a reverse osmosis unit. Featuring top quality ResinTech MBD-10 cation resin for high resistivity and high capacity.
Half granular coconut shell carbon and half activated alumina fluoride reduction resin.
1.5 pounds of KDF 55 with granular activated carbon. Extended chlorine reduction and heavy metal reduction.
A high quality nitrate reduction cartridge containing high capacity nitrate selective anion exchange resin. It can be regenerated to some degree with salt water, using the same method as with our softening cartridges. A cartridge this size will typically remove 5000 ppm / gallon (meaning, for example, if you have 10 parts per million nitrates in your water, you should change or regenerate it at about 750 gallons). Performance can vary considerably according to flow rate and other water constituents.
