Clean, safer‑tasting water—no tools, 5‑minute swap
Red-D 9" Replacement Cartridge for the Red-D Ultrafiltration Countertop Water Filter
- Exact replacement for the Red‑D Countertop Ultrafiltration system.
- Sub‑micron electro‑adsorptive media targets microbes, metals, and chemicals; replace every 6 months.
- Low pressure drop, high flow—designed for everyday kitchen use.
The proprietary and patented technology used in the Protector Red-D filtration is capable of removing submicron pathogens and inorganic contaminants through electro-adhesion and ion exchange. The filtration efficiency is comparable to ultra membrane filtration with the following exception; The Protector Red-D has a very low-pressure drop and high flow rates. It also has a high loading capacity so it works effectively in fresh, brackish, or salt waters. The media also includes powdered activated carbon with an average particle size of only 8 microns. At this particle size, activated carbon products remarkably high dynamic adsorption.
In the box & installation

FAQs
Will this fit other housings?
It’s specified for the Red‑D Countertop Ultrafiltration System. For other housings, contact us to confirm fit.
How often should I replace it?
About every 6 months under typical home use. Heavy use or poor source water may shorten this interval.
How does it compare to RO?
Red‑D focuses on sub‑micron contaminants (microbes, particulates, many organics/metals) with very low pressure drop. RO excels at dissolved salts/TDS but needs more pressure and typically wastes some water. Choose based on your water goals.
Is the media certified?
Manufacturer states the media is NSF/ANSI 61 and USP Class VI tested with endotoxin testing; whole‑system certifications vary.
