The Bottom Line
Reverse osmosis filtration is a water treatment process in which water is forced through a membrane that has very small holes. Clean water passes through and impurities that are too big to pass through the membrane are left behind and flushed away.
Pros
- Filters out most heavy metals and contaminants
- Uses no electricity
- Gives you fresh clean water at home
Cons
- May allow a few microbes to slip through
- Removes fluoride
Description
- Tap water is passed through a particle filter that removes silt and large particles.
- Next, an activated carbon filter traps minerals and contaminants.
- Water enters the Reverse Osmosis module under pressure, allowing only clean water to pass through.
- Treated water is passed through an activated carbon filter and is ready for use.
