Reverse Osmosis
Boise & Treasure Valley
The Purest Drinking Water in Boise & the Treasure Valley
Boise and the Treasure Valley's municipal water supply contains chlorine, chloramines, fluoride, nitrates, arsenic, and trace pharmaceuticals that standard filters simply cannot remove. Aqua Source's reverse osmosis systems use a multi-stage filtration process to remove up to 99% of dissolved contaminants — delivering hospital-grade pure drinking water straight from your kitchen tap. No more buying bottled water. No more worrying about what's in your glass.

What Does Reverse Osmosis Remove?
Treasure Valley tap water tests positive for dozens of contaminants that affect taste, odor, and long-term health. Our RO systems are independently tested to remove:
- Chlorine & Chloramines
- Fluoride
- Lead & Heavy Metals
- Arsenic
- Nitrates & Nitrites
- PFAS / PFOS
- Bacteria & Cysts
- Pharmaceuticals & VOCs
- Sediment & Turbidity
- Total Dissolved Solids (TDS)
How Our 5-Stage System Works
1
Sediment Pre-Filter
Removes dirt, rust, and particles down to 5 microns to protect the membrane.
2
Carbon Block Filter
Eliminates chlorine, chloramines, and organic compounds that damage the RO membrane.
3
RO Membrane
The heart of the system — removes up to 99% of dissolved contaminants at the molecular level.
4
Post Carbon Filter
Final polishing stage removes any residual taste or odor before water reaches your tap.
5
Remineralization Filter
Adds back healthy minerals — calcium, magnesium, and potassium — for great-tasting alkaline water.
