How a reverse osmosis drinking water system works

There are four distinct steps in reverse osmosis water filtration - pre-filtration, reverse osmosis, drainage and storage.
 
Pre-filtration
1. Pre-filtration
Water passes through a particle filter and activated carbon filter, reducing impurities like salt, sediment, chlorine, mercury, copper and pesticides.
Reverse osmosis
2. Reverse osmosis
Pressurized water is forced through a semipermeable membrane, trapping the smallest impurities and allowing only water to pass through.
Drainage
3. Drainage
The removed contaminants are flushed away while treated water moves to a storage tank.
Storage
4. Storage
Before the treated water reaches a faucet, it undergoes a final activated-carbon filtration to improve taste and quality for household use.
 

Multi-stage filtration for better water

  1. Sediment filter traps rust, sand and other large particles
  2. Carbon filter tackles bad tastes and odors, like chlorine
  3. Reverse osmosis filter reduces contaminants like lead, mercury, chromium and more
  4. Advanced specialty filters reduce pharmaceuticals, virus, bacteria and more
  5. Custom filters add minerals back in and increase the water’s PH
  6. Polishing filter makes water crisp and results in a better taste
