"When our power went out for three days after the storm, my neighbors were driving around looking for bottled water. I just filled a pot from the rain barrel and ran it through AquaGuard. My kids didn't even know anything was wrong."

"My parents live alone out in the county, and I worry every hurricane season. I sent them the Complete System and showed them how to use it over video call. Now I don't panic every time the forecast looks bad."
Sam B.
"We keep one in every vehicle now. After the winter freeze knocked out our water for a week, I told everyone in my family group chat to order one. It's the cheapest peace of mind I've ever bought."
Military-Grade
Filtration System
Removes 99.999999% of harmful substances
Here's what AquaGuard filters
Most Common Threats
Bacteria (Pathogenic & Fecal)
All too large to pass the 0.1-micron membrane.
- E. coli
- Salmonella
- Shigella
- Campylobacter
- Vibrio cholerae (cholera)
- Fecal coliforms
- Total coliforms
- Aerobic bacteria clusters
Why it matters: These are the most common causes of severe waterborne sickness.
Microplastics
Common in lakes, rivers, streams, and even tap water.
- Particles
- Fibers
- Fragments
- Beads
- Filaments
- Polymers > 0.1 microns
Why it matters: Microplastics are now found in over 80% of natural water sources.
Inorganic Sediment
Physically removed via mechanical filtration.
- Sand
- Silt
- Clay particles
- Rust flakes
- Soil residue
Why it matters: These are present in nearly every outdoor source.
Biological Hazards > 0.1 Microns
This covers a broad category.
- Worm eggs
- Larvae
- Nematodes
- Bacterial clusters
- Bio-contaminant fragments
Why it matters: Outdoor water often contains unseen biological threats.
Parasites & Protozoa
Also blocked due to size and cell structure.
- Giardia lamblia
- Cryptosporidium parvum
- Entamoeba histolytica
- Cysts
- Oocysts
- Protozoan larvae
Why it matters: These cause long-lasting stomach illness and dehydration.
Organic Matter
Trapped on the surface of the fibers.
- Algae
- Biofilm
- Plant matter
- Decaying leaves
- Natural debris
Why it matters: These affect both clarity and safety.
Turbidity & Visible Contaminants
Reduces cloudiness and improves clarity.
- Cloudiness
- Fine particles
- Suspended solids
- Murky water impurities
Why it matters: Clearer water = safer hydration.
Getting Started
HOW IT WORKS
Fill the bag with dirty water.
Hang the bag from a tree and let gravity do the work.
Clean water flows out of the filter.
Common Questions
Frequently Asked Questions
Product Details
AquaGuard uses a 4-stage micro-filtration system built around a 0.1-micron hollow-fiber membrane. Together with an activated carbon core, it mechanically removes bacteria (E. coli, Salmonella, Shigella, Campylobacter, cholera-causing Vibrio), parasites and protozoa (Giardia, Cryptosporidium, Entamoeba), microplastics, sediment, and organic debris — while the carbon stage strips odor, chlorine, and improves taste.
- Safe to use with: streams, rivers, lakes, ponds, rainwater, and stored tap water
- Not designed for: saltwater, chemically contaminated water, industrial runoff, or water with heavy metals
- Does not remove: viruses, dissolved chemicals, salts, or radiation
- Filter capacity: up to 400+ gallons before replacement
- No power, no batteries, no chemicals required
How do I use it?
No setup, no assembly required. Fill the gravity bag from any freshwater source — stream, lake, rain barrel, or stored water. Hang it using the built-in loop. Water flows down through the hose and filter core automatically, no pumping needed. Collect clean water in the pouch below, or sip directly through the mouthpiece.
Why do I need this when I can just boil water?
Boiling works, but it's not practical in most emergency situations. It requires fuel, time (minimum 10 minutes), a heat source, and a container — resources you might not have when the power is out. AquaGuard Pro provides safe drinking water instantly, with zero setup. Boiling also doesn't remove physical contaminants, heavy metals, or microplastics the way mechanical filtration does.
What exactly does the 0.1-micron filtration remove?
Our 0.1-micron hollow-fiber membrane removes:
- 99.99%+ of bacteria (E. coli, Salmonella, cholera, typhoid, etc.)
- 99.999% of parasites (Giardia, Cryptosporidium, Amoebas)
- 99.999% of microplastics
- Dirt, sediment, and turbidity
- With the activated carbon stage: chlorine, bad taste and odors
What water sources can I use it with?
Streams, rivers, lakes, ponds, and collected rainwater are all fair game. For the clearest results and longest filter life, fill from the cleanest water available and avoid heavy mud or silt. Steer clear of saltwater and any water you suspect contains chemicals or industrial runoff.
Will it expire if I keep it in my emergency kit?
No shelf life or expiration date when stored dry. AquaGuard Pro can sit in your emergency bag, vehicle, or home for years and work the moment you need it. Just store it in a cool, dry place. Note: if you've used it, let it fully air dry before storage to prevent mold growth.
Can my kids use it?
AquaGuard Pro requires moderate motor skills, so it's best suited for ages 5 and up with adult supervision. For younger children, we recommend an adult fills the bag and lets the child observe or assist with the hang-and-collect steps.
I live in the city or suburbs — do I really need this?
Urban and suburban households often have zero backup water source and are fully dependent on infrastructure that can fail. Boil-water advisories affect thousands of U.S. communities every year, and winter storms or hurricanes can knock out water treatment for days at a time — regardless of zip code.
How do I clean and maintain it?
Every 25–50 gallons (or when flow rate slows), backflush the filter using the included syringe: fill it with clean filtered water, attach to the outflow end, and forcefully flush backwards 3–5 times. This reverses flow and ejects trapped particles from the membrane, restoring flow rate to like-new. Between uses, shake out excess water and air dry before storage.
Warranty & Guarantee
Backed by a Lifetime Warranty — if any component fails from normal use, we replace it, free. And if AquaGuard Pro doesn't perform exactly as described, you have 60 days to return it for a full refund. No questions asked, no store credit — your money back.
