Shield 1000 Drinking Water Purification System
Mark Owen (Puralytics)
Shield 1000 Drinking Water Purification System is a LED-powered water purification unit.
The Shield 1000 is a water purification system designed by Puralytics which is useful for removing pathogens (bacteria, virus, protozoa), chemical contaminants (personal care products & pharmaceuticals), herbicides, and pesticides. The technology uses a photocatalytic nanotech fiber mesh to destroy contaminants in water. The Shield aims to improve humanitarian response by enabling access to safe drinking water while reducing water-borne diseases.

The patented Puralytics® process employs LEDs to excite a nanotechnology mesh which purifies water following five-step light-activated purification processes. The five-step process includes:
- Photocatalytic Oxidation – eliminates organic compounds
- Photocatalytic Reduction – reduces compounds & heavy metals to a 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 wavelengths more effective than UV irradiation
The Shield sterilizes pathogens, eliminates chemical toxins, and removes heavy metals from the water. The system delivers 100% treated throughput which doesn’t require chemical consumables and is scalable up to 100,000 liters per day.
Some of the technical specifications of the product include:
- 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
- Dimensions: 81.3 x 30.5 x 45.7 cm
- Weight: 27.2 kg
- Ambient operating temp: 5°C–30°C (41°F–86°F)
Many other schematics for UV bulb, internal components, and other components available in the Shield 1000 Owner’s Manual

Some of the replaceable components for Field Shield 1000 includes;
- Ozone cartridge(needs to be changed quarterly)
- UVC (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 are shipped back to Puralytics. Interview with representative
The designer specified performance targets include: 100% water recovery, removal of emerging contaminants (personal care products & pharmaceuticals), herbicides and pesticides, pathogens (bacteria, virus, protozoa), and industrial chemicals (petrochemicals, toxins) with no chemical consumables, and low generation of waste.
Only tested by the manufacturer. Interview with representative
Once a year maintenance schedule is recommended. The owner’s manual provides detailed safety information.
