What's Really in Your Tap Water?

Municipal water meets basic safety standards, but contains hundreds of contaminants that affect taste, health, and employee well-being. Here's what BWS filtration removes:

🧪

PFAS "Forever Chemicals"

EPA Standard: 4.0 ppt (parts per trillion)

76 million Americans have PFAS in their tap water. These industrial chemicals don't break down naturally and accumulate in the body, linked to cancer, thyroid issues, and immune suppression.

Common Sources:
  • Industrial discharge
  • Firefighting foam runoff
  • Food packaging contamination
  • Manufacturing facilities
BWS RO Removal: 99.9%
BWS UF + Carbon: 95%+
⚠️

Lead (Heavy Metal)

EPA Action Level: 15 ppb (parts per billion)

Even low levels of lead exposure cause developmental delays in children, cardiovascular issues in adults, and cognitive impairment. Older buildings in Georgia, Alabama, and Tennessee often have lead pipes or lead solder.

Common Sources:
  • Corroded pipes (pre-1986 buildings)
  • Lead solder in plumbing joints
  • Municipal system leaching
  • Brass fixtures & fittings
BWS Removal: 99%+
(Both RO and UF systems)
💧

Chlorine & Chloramines

Added to municipal water for disinfection, but creates unpleasant taste, odor, and chemical by-products (trihalomethanes) linked to increased cancer risk with long-term exposure.

Why It's Added:
  • Municipal disinfection requirement
  • Prevents bacterial growth in pipes
  • Required by EPA Safe Drinking Water Act
BWS Carbon Removal: 98%+
(All systems include activated carbon)

Dramatically improves taste & odor

🏭

VOCs & Pharmaceuticals

Industrial solvents, pesticides, and pharmaceutical residues pass through municipal treatment plants. These "emerging contaminants" require advanced filtration to remove effectively.

Examples Include:
  • Benzene & toluene (industrial solvents)
  • Atrazine & glyphosate (herbicides)
  • Hormones & antibiotics (pharmaceutical waste)
  • Microplastics (environmental pollution)
BWS RO Removal: 95-99%
(VOCs, hormones, antibiotics, microplastics)

How Multi-Stage Filtration Works

BWS systems use 4 or 5 filtration stages (depending on cooler model) to progressively remove contaminants, from visible sediment down to microscopic PFAS molecules. Here's the journey your water takes:

Understanding Microns (μm)

100 μm Human Hair
5 μm Stage 1 Filter
1 μm Stage 2 Filter
0.01 μm UF Membrane
0.0001 μm RO Membrane

1 micron = 1/1,000,000 of a meter. Smaller = better filtration.

🗜️

Stage 1: Sediment Pre-Filter

5 Microns

First line of defense that removes visible particles and protects downstream filters from clogging.

Removes:
  • Rust & corrosion particles
  • Dirt, sand, silt
  • Pipe scale & sediment
  • Visible debris
Lifespan: 12 months Material: Polypropylene

⬛

Stage 2: Activated Carbon Block

1 Micron

Compressed carbon block absorbs chemicals and organic compounds, dramatically improving taste and odor while protecting the membrane.

Removes:
  • Chlorine & chloramines (98%+*)
  • Volatile organic compounds (VOCs)
  • Pesticides & herbicides
  • Industrial solvents (benzene, toluene)
  • Trihalomethanes (THMs)
Lifespan: 12 months Material: Activated carbon

Stage 3: Primary Membrane (Choose Your System)

💎

Reverse Osmosis (RO)

0.0001 Microns

Ultra-fine membrane that forces water through microscopic pores, removing virtually all dissolved solids and contaminants.

Removes:
  • PFAS/PFOS (99.9%*)
  • Lead, mercury, arsenic (99%+*)
  • Total dissolved solids (TDS) (95%*)
  • Bacteria & viruses (99.9%*)
  • Fluoride, nitrates, sulfates
  • Pharmaceutical residues
  • Microplastics
Lifespan: 24-36 months* Efficiency: 99.9% removal* Drain Required: Yes (3:1 ratio)
🧬

Ultrafiltration (UF)

0.01 Microns

Hollow fiber membrane that removes bacteria and contaminants while retaining beneficial minerals for healthier water.

Removes:
  • PFAS/PFOS (95%+*)
  • Lead & heavy metals (99%+*)
  • Bacteria & cysts (99.9%*)
  • Chlorine (via carbon stages)
  • Sediment & turbidity
  • Rust & oxidized contaminants
Lifespan: 24-36 months* Efficiency: 95-99% removal* Drain Required: No (zero waste)
↓

Stage 4: BIO-SURE PLUS™ Select Models

Mineral Enhancement

Advanced mineral infusion technology adds back essential minerals for healthier, better-tasting alkaline water (8.5-9.5 pH).

Adds:
  • Calcium (bone health)
  • Magnesium (cardiovascular support)
  • Potassium (electrolyte balance)
  • Trace minerals (overall wellness)
Lifespan: 12 months pH Range: 8.5-9.5 (alkaline) Available: Select cooler models

✨

Stage 5: Post-Carbon Polishing

Final Refinement

Final activated carbon stage removes any residual taste or odor, ensuring crisp, clean water at every pour.

Polishes:
  • Residual tastes & odors
  • Any remaining organic compounds
  • Final water refinement
Lifespan: 12-18 months Material: GAC (Granular Activated Carbon)
