Under Counter Filtration | 4300 NANOTECHNOLOGY GEN3 CERTIFIED UNDER COUNTER FILTRATION SYSTEM
In response to continuous feedback from embassy and consulate facility management teams and medical professionals, the B. David Company has developed our third generation residential drinking water system. We are confident that this system represents the most sophisticated and advanced under-counter purification solution presently available.
System Enhancements:
The flow rate has increased from 0.5 to 1.0 gallon per minute. Filter replacement intervals have been extended to every 2,000 gallons, doubling the previous capacity of 1,000 gallons. The system now features an upgraded durable ceramic faucet, and has achieved the NSF/ANSI 372 certification for microplastic reduction.
Ongoing DoS Requirements:
Environmentally responsible: This system is designed with sustainability in mind. It operates without requiring electricity and does not waste water. It also holds third-party certification to NSF/ANSI P-231, widely regarded as the definitive standard for the removal of viruses and bacteria from drinking water. Additionally, this system holds the prestigious IAPMO Platinum Seal for exceptional quality and performance.
Ease of Maintenance: Maintenance is streamlined and efficient, requiring 30 minutes per year, minimizing disruption while ensuring optimal system performance.
Quality Assurance: The system is assembled at a facility inspected and approved by IAPMO, ensuring the highest standards of manufacturing and quality control.
Use with Confidence:
Since 1995, we have proudly supplied the U.S. Foreign Service with our state-of-the-art water purification systems. Leveraging the latest technology, our systems are trusted in thousands of U.S. Government housing facilities worldwide.
B. David Company Nano Technology vs. Distillation:
- Requires only a fraction of the maintenance
- The average post may save up to $350.00 per year per distiller in electrical costs when switching to our 4300 Nanotechnology Gen3 Certified Under Counter Filtration System. No need to clean scale from boiling chambers and there are no water reservoirs to maintain.
- Water on demand, producing 1.0 gallon per minute
- Security – a vulnerable power supply is not required
Contaminant Removal (partial list):
- Reduces parasitic protozoan cysts such as Giardia and Cryptosporidium
- Removes waterborne contaminants such as bacteria, viruses, and colloidal particles
- Captures particles as large as tens of microns or as small as .01 microns
- Reduction of microplastics
- High Dirt and particulate retention – up to 25 times more than a conventional 10” filter
- Removes many micro-pharmaceuticals
- Reduces lead below Federal Action Level of 10 ppb
- Removes volatile organic compounds (VOCs), pesticides, herbicides, and many chemicals
4310 Nanotechnology Certified Replacement Filters 3-pack contains all three filters for this system: 4301 DE Cartridge with FI – first stage, 4302 DF cartridge – second stage, 4303 Advanced Nano Filter – third stage.
