bdc-6000bb nanotechnology certified whole home system


Contaminated bath and shower water is a reality in many international residential bathrooms. Just a small amount of water ingested through the mouth, eyes, nose, lesions in the skin, and or inhalation of aerosolized bacteria can result in infection and potentially serious illness.

Many in the medical and facilities community believe it should be mandatory for bathroom water to have the same safety standards as at the kitchen faucet.”

Consequently, the B. David Company is pleased to announce the introduction of our new NSF rated, third-party certified – BDC-6000BB Nanotechnology Certified Whole House Purification System. This next generation water purifier incorporates our proprietary nanotechnology, TC0-3 treated carbon, and a new patented electrostatic media. The first stage high-capacity pre-filter has an independent shutoff valve for easy filter replacement. Connects easily to your incoming water supply, delivering up to 8-gallons of purified water per minute. The filtration capacity has increased from 25,000 to 35,000 gallons versus the previous generation POE system. This product is listed under GSA contact GS-07F-9166S. We believe that this is the first whole house purifier of its kind.


  • Provides maximum protection at all water outlets in your entire residence, including kitchen, bathroom (shower/bath), and laundry. A child drinking contaminated water from the bathtub or brushing their teeth with tainted water is no longer a risk.
  • Green technology – This is an environmentally responsible system as no electricity or chemicals are used. No water is wasted.
  • Built in the USA at an EPA inspected facility.
  • Very low maintenance – Filter replacement normally takes less than 15 minutes.

  • Certified to NSF standards P-231 (virus and bacteria), NSF/ANSI 42 aesthetics (Particulates Class 3) and NSF/ANSI 53 (Cyst) by the International Association of Plumbing and Mechanical Officials (IAPMO). IAPMO is a leading global independent third-party certification and drinking water testing organization. IAPMO Platinum Seal TM recipient for exceptional quality and function. 

Capacity and Filter Components:

6001 – Sediment with S2 reduction (first stage) – Captures dirt, sediment, particulate matter. Replace every 5,000 – 15,000 gallons or six months. (6001 replacement filters are ordered in a case pack of 6).

6002 – Parallax Nano Filter (second stage) – Removes, virus, bacteria and cysts. Replace after 35,000 gallons or 18 months.

6003 – Activated Carbon Media with TCO-3 (third stage) – Removes many chemicals, chlorine, odor, and improves tasteReplace after 35,000 gallons or 18 months.

6004 – Anti-Bacterial with H1A (fourth stage) – Removes, virus, bacteria, cysts, and heavy metal reductionReplace after 35,000 gallons or 18 months. (Replacement  6002, 6003, and 6004 filters can be ordered in one convenient case pack – 6010  3-pack).

  • 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 .015 nanometers
  • Wide pH Ranges – Effective from pH 4 to pH 9
  • High Dirt and particulate retention – Up to 25 times more than conventional 20” filter.

Particulate Reduction:

These collective technologies are very effective for the reduction of Lead, Ferrous Iron, PCBs & BPAs, Polysaccharides, Chromium VI, micro-pharmaceuticals, colloidal particles, and synthetic chemicals such as polyfluoroalkyl (PFAS).

Additional health considerations:

  • Legionnaires’ disease can be transmitted when airborne droplets carrying the Legionella bacteria are inhaled into the lungs during shower.
  • Contaminated shower water can cause many types of diarrheal diseases, including Cholera, Typhoid, and Dysentery.
  • The human body can absorb 100 times more chlorine in a 10-minute unfiltered shower than from drinking a gallon of water.
  • Just a drop of water on a toothbrush can lead to illness.
