The Reverse Osmosis Promise — and Its Hidden Drawbacks
Reverse osmosis (RO) systems are often marketed as the ultimate solution for clean water. They push water through a semi-permeable membrane to remove nearly every dissolved substance. Sounds perfect, right?
The catch: RO doesn’t discriminate between bad and good. It removes everything — including natural minerals like calcium, magnesium, and potassium that are essential for hydration and taste (World Health Organization).
And that’s not all. Most RO systems waste three to five liters of water for every liter of filtered water they produce (U.S. EPA – WaterSense). That’s clean tap water going straight down the drain every time you fill a glass.
When “Pure” Becomes Too Pure
Water that has been stripped of all minerals may look crystal clear, but it’s not always what your body needs. Demineralized water can be slightly acidic, flat-tasting, and less effective at replenishing electrolytes.
According to the U.S. Geological Survey (USGS) and Healthline, reverse osmosis water typically measures between pH 5.5 and 6.5 because removing calcium and magnesium eliminates the minerals that buffer acidity.
In daily life, what most people need isn’t lab-grade distilled water — it’s clean, mineral-rich water that supports health and taste.
The 5+1 Stage Difference
PJURE’s 5 + 1 stage filtration system removes what you don’t want — chlorine, PFAS, lead, bacteria, and microplastics — while keeping what your body does need.
What happens inside:
-
Protective Mesh:
Safeguards structure and distributes water evenly across the filter.
-
Non-woven Sediment Layer:
Traps sand, rust, and larger particles to protect the inner layers.
-
Activated Carbon Block:
Removes chlorine, VOCs, pesticides, and chemical residues — improving taste and odor.
-
KDF Layer (Copper-Zinc Alloy):
Reduces heavy metals, bacteria, and prevents microbial growth within the filter.
-
PP Membrane:
Performs micro-filtration to capture fine particles and microplastics.
-
+1 Mineralization Media:
Adds trace minerals like calcium and magnesium for better taste and natural balance.
Unlike RO, this process preserves beneficial minerals and uses zero wastewater.
Clean Water, Simplified
Most RO units come with bulky tanks, pumps, and visible tubes under (or even on top of) your counter. They require professional installation and regular maintenance.
PJURE’s stainless system fits seamlessly under your sink, requires no electricity, and uses only one compact replacement cartridge once a year. It’s clean design that actually makes sense.
The Smarter, Sustainable Choice
RO filtration has its place — for laboratories or industrial use — but for daily hydration, it’s overkill.
PJURE offers a better balance
✅ No wastewater
✅ No tank
✅ No electricity
✅ No mineral loss
Just pure, great-tasting water from your tap — every day.
