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.
Guide Review - Watts Water Filtration System
Reverse osmosis can remove dissolved minerals that cause hardness, toxic chemicals and other impurities. It can improve the taste of your water, plus treated water will not produce a mineral build-up in kettles and coffee makers. Reverse Osmosis units may also remove contaminants such as chromium, mercury and nitrates. Reverse Osmosis also removes fluoride.
