Frequently Asked Questions

Q: How do I know when to replace the filter?

When the flow rate drops significantly and repeated cleaning doesn’t restore it, it’s time for a new element. Also, if the carbon core has been used for months, taste or odor may reappear, signaling it’s time for replacement.

Q: Can I clean the Gravidyn filter element?

Yes! The ceramic shell is fully cleanable using a soft brush or pad. Simply remove surface buildup, rinse with clean water, and reinsert into your system. Do not wash with soap or chemicals.

Q: Does this remove viruses from water?

The 0.2-micron ceramic layer removes bacteria and protozoa, but it does not remove viruses. For viral protection, pair with a purifier or chemical disinfectant in high-risk areas. ✅

Q: How many filters do I need?

The Katadyn TRK Drip Gravidyn system requires 3 filter elements to operate at full capacity. You can replace them one at a time or all at once depending on usage and wear.

Ideal For:

• ️ Outdoor Adventurers

Benefits You Can Count On

This isn’t just a filter — it’s a mission-critical tool that protects you from harmful contaminants while delivering better-tasting water. The activated carbon layer goes beyond filtration to eliminate chlorine, pesticides, and chemical residues that can linger in surface or tap water. Unlike plastic-heavy disposable filters, this ceramic element lasts longer, performs better, and reduces waste.
