Katadyn TRK Drip Ceradyn Gravity Water Filter — 150k L, 0.2-micron Ceramic

The Katadyn TRK Drip Ceradyn is a free-standing gravity water filter designed for off-grid living and emergency readiness. It uses a 10-liter reservoir and a field-cleanable 0.2-micron ceramic depth filter. The Ceradyn version ships with three ceramic elements for extended life, making it well-suited for cabins, base camps, or remote locations where reliable drinking water matters.

With a gravity-fed flow, you can produce about 4 liters of drinking water per hour without electricity. The ceramic filter features a micro-porous structure impregnated with silver, which helps slow microbial growth and keeps the filtration path ready for action between cleanings. Depending on water quality, the Ceradyn can handle up to about 150,000 liters over its lifetime, offering a long-term solution for off-grid kitchens, camps, and preparedness kits.
