Not All Filters Are Created Equal

When it comes to drinking water, Reverse Osmosis is the gold standard. Standard filters can’t remove the smallest and most dangerous contaminants. These include PFAS, fluoride, heavy metals, bacteria, viruses and pharmaceutical residues.

Reverse Osmosis does what no ordinary filter can, delivering bottled-quality water on demand in your own home.

What Is Reverse Osmosis?

Reverse Osmosis (RO) is an advanced water purification technology that uses a semipermeable membrane to remove virtually everything but pure H₂O.

This membrane has pores as small as 0.0001 microns, allowing only water molecules through — and blocking contaminants as small as viruses.

It’s what hospitals, laboratories, and high-end restaurants rely on for purity — and now, it’s available in your home.
