How Free²col works (in plain language)
Free²col releases copper ions (Cu²⁺) into water. Copper disrupts enzymes and cell walls in many bacteria, algae and fungi, helping keep stored water safe. It disperses quickly and stays in solution until the treated water is used.

- Households using borehole or municipal storage tanks
- Schools & clinics needing reliable, low-taste water treatment
- Farms & packhouses (hand-wash, canteen, storage tanks)
- Construction & mining sites with mobile tanks and bowsers
- Events & emergency supply where water is stored before use
How to use Free²col (step-by-step)
- Measure the correct dose for your volume (see tables above).
- Add and mix thoroughly so the product disperses evenly.
- Wait 30 minutes before drinking.
- Store covered to avoid re-contamination.
- Re-dose when new untreated water is added to the tank.

Safety & Compatibility
Taste/odour: Free²col is chlorine-free; no chlorine taste or smell when dosed correctly.
Viruses & protozoa: Copper is less effective against viruses and some cysts (e.g., Giardia/Cryptosporidium). For high-risk sources, combine with filtration/UV/boiling.
Guidelines: Keep finished-water copper within recognised drinking-water limits (e.g., WHO guideline about ≤ ~2 mg/L). Follow the label and our dosing chart.
Sensitive groups: People with Wilson’s disease or on copper-restricted advice should consult a healthcare professional.
Plumbing: Staying within the recommended dose avoids blue/green staining and compatibility issues.
