Gravity Well Nano Membrane Water Filter System for Fluoride and Radiation

Gravity Well Nano Membrane Emergency Water Filter System with Fluoride and Radiation Remediation: High-Flow Gravity Purifier for Virus-Free Survival Water

The only gravity water filter system that also works as a personal water straw. Attach the included tube and use as a portable hiking filter.

Protection for your family's hydration in any crisis with the Gravity Well Ultra Emergency Water Filter System—the fastest high-flow gravity water purifier delivering an hourly through-put of Up To 12+ gallons per hour of crystal-clear, safe drinking water. Engineered for preppers, homesteaders, and off-grid adventurers, this portable survival water system combines advanced ultra-filtration membrane with either our 3 stage Fluoride filter, or stainless steel Bone-Char filter media.  99.9999% of bacteria, viruses, protozoa, and contaminants like heavy metals and pesticides. Unlike standard gravity filters (e.g., Berkey or AquaCera) that overlook viruses, the UF filter removes 99.9% of virus size particles to remove pathogens quickly and efficiently in real-time, ensuring hospital-grade protection without chemicals or boiling.

What is a Nano UF Filter? A Nano UF (Ultrafiltration) filter membrane is a physical, filtration barrier used in water treatment. It is like a mini Reverse Osmosis filter without wasting water through a bypass. It uses microscopic pores .02 microns to remove suspended solids, bacteria, viruses, and large molecules while allowing water and beneficial dissolved minerals to pass through

In a world where tainted water supplies claim 800,000 lives yearly—from Flint's lead crisis to aging infrastructure—don't gamble on unsafe sources. Harvest from ponds, streams, or rainwater and produce drinking-ready water effortlessly. Dual-mode operation (gravity or pressure-assisted via solar powered air pump) makes it versatile for bug-out bags, cabins, or family emergencies. Use freely supplied gravity for standard production or the included USB powered air pump and Included solar panel and this system will produce more water than you can possibly use when the grid fails.

Key Features of the Gravity Well Nano Membrane Water Filter System

• UF Nano Membrane Filter: .02-micron pores remove Virus, Bacteria, Giardia, Cryptosporidium, rust, sand, and many other suspended particles.
  • Easily connect the included tubing and use the filter as a hiking water straw
• USB Solar Panel: While not needed to produce water, You can use the included Solar panel to operate the Accelerator Air Pump in times of very high water production is needed. You can recharge other devices like phones and radios.
• Rugged, Portable Design: BPA-free USA-made containers with paracord 550 handle (doubles as emergency cordage), locking lids, stackable build, and high-impact dispenser spout.
• Versatile Modes: Gravity-fed for passive use or pressure-assisted using the Accelerator Air Pump for speed—ideal for off-grid water purification in camping, RVs, or SHTF setups. (Can also use the connection tube and use the Nano Membrane like a Lifestraw(tm) water filter while camping.

How the Gravity Well Nano UF Membrane Water Purifier Works

Ultrafiltration (UF) is a membrane-based water filtration technology that uses hydrostatic pressure to force water through a semi-permeable membrane with very small pores. It physically sieves out contaminants larger than the pore size while allowing clean water.

Then the water passes through Activated Carbon Filter...

This filter comes in 2 options: Choose either the 3-Stage replaceable cartridge or refillable Bone char filter. Bone Char is one of the most porous materials known to man. If you could measure the surface area of the bone-char in our filter and spread it out, it would cover 7 acres.  Incredibly absorbent material that acts like a vacuum cleaner sucking up contaminants.

Both options are great at:

• Fluoride — Its standout capability; widely used in defluoridation in areas with naturally high fluoride in groundwater.
• Heavy metals — Lead, arsenic, cadmium, mercury, aluminum, etc. (via adsorption and ion exchange).
• Chlorine and chloramines — Similar to regular carbon.
• Organic compounds — Some color bodies, THMs (trihalomethanes), and other organics.
• Radioactive particles/isotopes — effectiveness in some applications.
• Other — Iron, manganese, and certain anions.

1. Setup: Assemble the 3.5-gallon upper/lower chambers (total 7 gallons). Attach the Nano Membrane Filter to the Stainless Steel J-Tube assembly and insert into the upper chamber.
2. Connect your 3-Stage filter and adapter to the bottom of the dirty water container. (Stainless Steel secondary filter slides into lid of bottom clean water container)
3. Place dirty water container on the top of the clean water container and screw down.
4. Fill : Pour untreated water into the top. For fast mode, screw dirty water container lid down and connect the USB powered Accelerator Air Pump
5. Purify: Gravity or pump forces water through the filters removing 99.9999% of threats. Collect from the dispenser spout—ready in minutes.
6. Maintain: Washing our the nano Membrane filter is easy. Using clean filtered water, rinse and gently rub the membrane. Rinse off and reinstall.

Pro Tip: Test on pond water like our customers—tastes great and virus-free! Total blackout prep. Always prioritize safety.
