Shield 1000 Drinking Water Purification System
LED-powered water purification unit.
The Shield 1000 is a water purification system, which uses a photocatalytic nanotech fiber mesh to destroy contaminants in water. A photochemical reaction that occurs when the mesh is activated by UV energy and, when coupled with intense UV affect on contaminants, results in the five processes that purify the water. The Shield aims to improve humanitarian response by enabling access to safe drinking water more efficiently, while reducing water-borne diseases.

Product has been patented
The Shield is purchased from Puralytics (or another retailer) by large-scale NGOs, governmental agencies, or non-profits and then donated to disaster relief. Community members can retrieve water from a tank hooked up to The Shield. Interview with representative
The patented Puralytics® process employs LEDs to excite a nanotechnology mesh, which drives five, light-activated purification processes within the water stream.
The Shield sterilizes pathogens, eliminates chemical toxins and removes heavy metals from the water. The system delivers 100% treated throughput, doesn’t require chemical consumables and is scalable to 100,000 liters per day.
Dimensions: 81.3 x 30.5 x 45.7 cm
Weight: 27.2 kg
Many schematics for UV bulb, internal components, and other components available in the Shield 1000 Owner’s Manual
Support is provided by Pure Health Water, authorized dealer of Puralytics. Interview with representative
There is a replaceable ozone cartridge that needs to be changed quarterly and a UVC bulb that needs annual replacement. The catalyst may need replacing at some long interval dependent on the application.
The LEDs will illuminate with full power for about 3 years. Replacements are only available if the products is shipped back to Puralytics.
- Water recovery: 100%
- Water production: 0.5-2.6 L/min (200–1000 gallons per day)
- Pressure drop: 5–25 psi @ 200-1000 gpd
- Power consumption: 570 Watts
- Power input: 100-240 V; 50 Hz-60 Hz
- Ambient operating temp: 5°C–30°C (41°F–86°F)
- Photocatalytic Oxidation – eliminates organic compounds,
- Photocatalytic Reduction – reduces compounds & heavy metals to less toxic state,
- Photoadsorption – irreversibly adsorbs heavy metals; mercury, lead, chromium, arsenic, etc.,
- Photolysis – high energy breaks up chemical compounds to enhance the other processes,
- Photodisinfection – high intensity multiple wave lengths more effective than UV irradiation.
With proper pre-treatment system integration, high quality potable water can be achieved from a wide array of contaminated water sources with >90% water utilization, no chemical consumables, and low generation of waste.
