Select 40 PackThe hard truth
When clean water disappears, store shelves empty fast.
In a real crisis, you may be dealing with rainwater, standing water, a creek near your neighborhood, or a questionable freshwater source after utilities fail.
- ✓No power needed. No batteries. No boiling. No waiting for tablets.
- ✓Small enough for every bag, vehicle, and family member.
- ✓Pure mechanical filtration built for long-term readiness.
Why serious preppers switch
10x finer filtration than common 0.1–0.2 micron straws.
PureFlow filters to 0.01 microns and is built to remove 99.9% of bacteria, protozoa, and microplastics through mechanical microfiltration.
Honest safety note: PureFlow does not remove viruses, chemicals, heavy metals, saltwater, or industrial runoff. For virus concerns, pair with purification tablets or UV. For chemicals, use activated carbon or reverse osmosis.
How it works
No power. No training. No moving parts.
Three simple stages help turn questionable freshwater into drinkable water when conventional systems are unavailable.
01
Pre-filter mesh
Captures sand, silt, sediment, and visible debris to protect the inner filtration membrane.
02
0.01-micron hollow fiber membrane
Thousands of microscopic fibers physically block bacteria, protozoa, and microplastics.
03
Clean water outlet
Filtered water exits through the mouthpiece for immediate drinking from compatible freshwater sources.

Know your gear before you need it.
Can I store this in my bug-out bag for years?
Yes. Store it sealed in a cool, dry place. Make sure it is completely dry before long-term storage to prevent mold.
How does 0.01 micron compare to other common brands?
Common straw filters are often 0.1–0.2 microns. PureFlow filters to 0.01 microns, which is 10–20x finer by pore size.
Does it remove viruses, chemicals, or heavy metals?
No. It is a mechanical microfilter for bacteria, protozoa, and microplastics. Pair with purification tablets or UV for virus concerns, and use activated carbon or RO for chemical contamination.
How long does 1,800 gallons actually last?
At one gallon per day, 1,800 gallons is nearly five years of drinking water from one straw.
How many should I buy for my family?
At minimum, buy one per family member. Many prepared families keep extras in a home cache, vehicle kit, bug-out bag, and go-home bag.
What water sources can I use it with?
Use it with freshwater sources like rivers, lakes, streams, ponds, puddles, rainwater collection, and ditches. Do not use with saltwater or industrial chemical runoff.
Preparedness starts with water
Your family’s water security should not be an afterthought.
