In a world where access to safe drinking water isn’t always guaranteed, NACS (Natural Antibacterial Cleaner Solution) provides a practical, reliable, and powerful method to purify questionable water sources on demand. Whether you’re hiking, camping, traveling internationally, or preparing for emergencies, NACS offers a trusted, field-tested solution that transforms potentially harmful water into a safe and drinkable resource.
What is NACS?
NACS is a two-part water purification kit designed for on-site chlorine dioxide production. It includes:
- Part 1: A 28% sodium chlorite solution (22.4% Sodium Chlorite, 5.6% inert salts, and the remainder distilled water).
- Part 2: A 50% citric acid solution.
When equal parts of Part 1 and Part 2 are combined, they create chlorine dioxide (ClO₂)—a highly effective biocide that kills all known pathogens, including bacteria, viruses, and parasites.
Just three drops of each part, allowed to activate for 30 seconds in a clean, dry glass, can then be added to a quart of questionable water, making it safe to drink in minutes.
Trusted by the Military and Adventurers Alike
This very same two-part solution is used by military personnel in the field, where reliable water sources are scarce. It’s also a favorite among:
- Hikers and campers
- International travelers
- Survivalists
- Exploratory missions
The simplicity, portability, and effectiveness of NACS make it an essential addition to any emergency preparedness or travel kit.
How Chlorine Dioxide Works
Once activated, chlorine dioxide releases an active form of oxygen, acting as a powerful oxidizer and antimicrobial agent. It targets and destroys pathogens in the water, breaking down into simple saline (salt) after about 30 minutes. This natural breakdown makes it safe, residue-free, and environmentally friendly.
CDS 3000 PPM: A Convenient Alternative
For those who prefer a ready-made option, Chlorine Dioxide Solution (CDS 3000 PPM) is also available. Created via a distillation process, CDS is a pre-infused solution of chlorine dioxide gas in water, offering a convenient, clean-tasting version of this powerful sanitizer.
- CDS 3000 PPM contains 3,000 parts per million of chlorine dioxide.
- According to Paris Humble (daughter of Jim Humble, originator of MMS), the MMS to CDS conversion ratio is 1 to 8.
- That means if a water treatment calls for 3 activated drops of the two-part NACS, you would need 24 drops of CDS 3000 to match its effectiveness.
CDS 3000 is often favored for daily use or maintenance because of its milder taste and convenient dosing. However, the freshly activated two-part method remains the gold standard for maximum on-demand power, especially in rugged or emergency situations.
Used Worldwide in Industry and Municipal Water Systems
Chlorine dioxide isn’t just for outdoor enthusiasts—it’s been used since the early 1900s in industrial and municipal applications:
- Food Processing: Sanitation of meat (pork, poultry, seafood), fruits, vegetables, and dairy.
- Municipal Water Systems: Preferred over chlorine due to being 2.5 times more powerful and effective against tough parasites like Giardia lamblia and Cryptosporidium parvum.
- Hospitals and Restaurants: Used to sanitize surfaces without requiring a rinse.
Its efficiency, safety profile, and lack of toxic residue have earned it global recognition as one of the most reliable biocides available today.
Safe for Daily Use
Unlike chlorine, chlorine dioxide does not form harmful chlorates or toxic byproducts. It simply reduces to saltwater after doing its job. When used properly and per label instructions, it is safe for everyday use on:
- Fruits and vegetables
- Raw meats
- Food prep surfaces
- And of course—drinking water
Why You Should Have It On Hand
From international travel to wilderness adventures—and even home emergencies—chlorine dioxide drops are increasingly found in first aid kits, emergency supplies, medicine-and-kitchen cabinets.
Imagine this scenario: You’re traveling abroad and have doubts about the tap water served at a restaurant. You simply activate a drop or two of each part of NACS in a glass and swirl them together, wait 30 seconds, pour in your water, and wait a minute. Now it’s safe to drink.
Or maybe you’re at home, and a natural disaster or infrastructure failure leads to contaminated municipal water. Rather than boiling water (which takes time and fuel), you could purify water instantly using NACS.
In such cases, chlorine dioxide is a lifesaver.
How to Use NACS (Water Purification Drops)
- Place 3 drops of Part 1 (sodium chlorite) into a clean, dry glass.
- Add 3 drops of Part 2 (citric acid) to the same glass.
- Swirl gently and let the mixture activate for 30 seconds.
- Add the activated drops to one quart of water.
- Wait 1 to 5 minutes, depending on water clarity and temperature, then drink.
For CDS 3000: Use 24 drops per quart of questionable water, since it’s a diluted, pre-infused form.
Chlorine Dioxide Water Purification Drops (NACS and CDS) are:
✅ Powerful against all known pathogens
✅ Safe and non-toxic when used as directed
✅ Easy to use in the field or at home
✅ Trusted by military, travelers, and emergency responders
✅ Essential for emergency and survival kits
Whether you opt for the freshly activated NACS two-part drops or the pre-made CDS 3000 PPM, you can rest easy knowing that you have one of the most effective water sanitizers in the world in your hands.
