A filter that works when everything else fails AND a lifetime warranty? No brainer. I ordered six, one for each family member's bug out bag, plus extras for the house and both vehicles. It's the kind of thing you pray you'll never need, but knowing we can drink safely from any water source if disaster strikes lets me sleep at night.

Here's what the Oasis Straw filters
MOST COMMON THREATS...
Bacteria (Pathogenic & Fecal)
E. coli, Salmonella, Shigella, Campylobacter, Vibrio cholerae, fecal coliforms, total coliforms and aerobic bacteria clusters. All too large to pass the 0.1 micron membrane. These are the most common causes of severe waterborne sickness.
Parasites & Protozoa
Giardia lamblia, Cryptosporidium parvum, Entamoeba histolytica, cysts, oocysts and protozoan larvae. Also blocked due to size and cell structure. These cause long lasting stomach illness and dehydration.
Microplastics
Particles, fibers, fragments, beads, filaments and polymers. Common in lakes, rivers, streams, and even tap water. Microplastics are now found in over 80% of natural water sources.
Organic Matter
Algae, biofilm, plant matter, decaying leaves and natural debris, trapped on the surface of the fibers. These affect both clarity and safety.
Inorganic Sediment
Sand, silt, clay particles, rust flakes and soil residue, physically removed via mechanical filtration. These are present in nearly every outdoor source.
Turbidity & Visible Contaminants
Cloudiness, fine particles, suspended solids and murky water impurities. The straw reduces cloudiness and improves clarity. Clearer water = safer hydration.
Biological Hazards Larger Than 0.1 Microns
Worm eggs, larvae, nematodes, bacterial clusters and bio contaminant fragments. Outdoor water often contains unseen biological threats, and this covers a broad category of them.
FAQ
?Why do I need this when I can just boil water?
While boiling works, it's not practical in most emergency or outdoor scenarios. Boiling requires fuel, time, a heat source, and a container, resources you might not have when seconds count. In a wildfire evacuation or hurricane, you won't have time to set up a fire and wait. The Oasis Straw provides instant, safe drinking water the moment you need it, with zero setup. Plus, boiling doesn't remove physical contaminants or microplastics. Our advanced filtration does.
?What exactly does the 0.1 micron filtration remove?
Our 0.1 micron hollow fiber membrane removes: 99.999999% of bacteria (E. coli, Salmonella, Cholera, Typhoid, etc.), 99.999% of parasites (Giardia, Cryptosporidium, Amoebas), 99.999% of microplastics, plus dirt, sediment, and turbidity. With our activated carbon stage: chlorine and bad taste and odors.
?Will it expire if I just keep it in my emergency kit?
Absolutely no shelf life or expiration date when stored dry. The Oasis Straw can sit in your emergency bag, vehicle, or home for 10, 20, even 50 years and work perfectly the moment you need it. Just store it in a cool, dry place and it's ready whenever disaster strikes. If you've used it, let it fully air dry before storage to prevent mold growth.
?How many should I buy for my family?
We recommend following the prepper principle: two is one, one is none. Always have backup systems. For a family of four or five, we suggest a minimum of 5 straws, one each, and 10 as the recommended setup, two per person, so everyone can drink simultaneously if you encounter a water source, plus backup.
?Can my kids use it?
The Oasis Straw requires moderate suction, so it's perfect for kids ages 5+. For younger children or toddlers, we recommend using the squeeze bag attachment to filter water directly into their bottles. This versatility is why we designed the system to work multiple ways.
?I live in the city/suburbs - do I really need this?
Urban and suburban families are often at HIGHER risk. Why? You have zero alternative water sources and are 100% dependent on infrastructure that can fail instantly. Flint, the Texas 2021 storm, boil water advisories, Hurricane Harvey, and aging infrastructure have all left city households with nothing. Rural folks have wells, streams, rainwater collection. City dwellers have faucets that only work when the system works. When it fails, you're in the most dangerous position. The Oasis Straw transforms you from helpless and dependent to self sufficient in seconds.
?How do I clean and maintain it?
Every 25-50 gallons, or when flow rate slows, backflush the filter using the included syringe. Fill the syringe with clean filtered water, attach to the outflow end, and forcefully flush backwards 3-5 times. This reverses water flow and ejects trapped particles from the membrane. That's it, flow rate restored to like new. Between uses: shake out excess water and air dry completely before storage. We include a protective cap to keep your mouthpiece sanitary.
?What's your return policy?
We offer a 60-Day Risk-Free Trial and Lifetime Happiness Guarantee with our lifetime warranty. If you're not completely satisfied with the Oasis Straw for any reason within 60 days, return it for a full refund, no questions asked. Beyond that, we stand behind our product for life. If there's ever a manufacturing defect or issue with your straw, we'll replace it free of charge. The only way you 'lose' is by not having this when you need it.
