Summary
1. Reverse Osmosis was designed for desalinating sea water. It is useful for reducing very specific chemical contaminants like fluoride, nitrates.
However, according to the World Health Organization, low (TDS-Total Dissolved Salts) water or demineralized water produced by reverse osmosis or distillation, remove the essential nutrients and is not suitable for long term human consumption and in fact, can create negative health affects to those consuming it.
RO purification systems are difficult to maintain - need lot of servicing.
2. Carbon Filtration is good to remove
chlorine,
organic compounds (pesticides, herbicides, insecticides),
some heavy meatals (iron, lead, aluminium, cadmium),
some cysts,
some parasites,
Another good thing is, it doesn't remove
Dissolved Solids - Sodium, Calcium, Magnesium, and inorganic minerals.
It does not remove
Fluorides
Sulfates
Nitrates
Reverse Osmosis
Reverse osmosis is best suited to address the two issues for which it was originally designed:
- Desalinating brackish water or sea water and/or
- Reducing very specific chemical contaminants.
You might need RO if you are facing challenges with
flouride,
sodium,
total dissolved solids (TDS)
chemicals like
arsenic,
radium,
nitrates and
nitrites, etc.
And while reverse osmosis water filters will reduce a pretty wide spectrum of contaminants such as dissolved salts, Lead, Mercury, Calcium, Iron, Asbestos and Cysts, it will not remove some pesticides, solvents and volatile organic chemicals (VOCs) including:
Ions and metals such as Chlorine and Radon
Organic chemicals such as Benzene, Carbon tetrachloride, Dichlorobenzene, Toluene and Trihalomethanes (THMs)*
Pesticides such as 1,2,4-trichlorobenzene, 2,4-D and Atrazine.
Is demineralized water produced by reverse osmosis or even distillation good for you?
No, it’s actually not. According to the World Health Organization, low (TDS) water produced by reverse osmosis or distillation is not suitable for long term human consumption and in fact, can create negative health affects to those consuming it. This lack of minerals also contributes to the awful taste that reverse osmosis water is known for. Stay tuned for our next blog post which will focus on the negative health effects of demineralized water produced by reverse osmosis and distillation.
What does this all mean?
Reverse osmosis was originally invented as a means of desalinating brackish or seawater sources and should be used as the tool for which it was intended.
Contrary to its reputation, reverse osmosis does not remove 100% of all contaminants and both reduction rates and certifications vary widely depending on the contaminant in question
RO membranes can be damaged and destroyed by the chlorine found in most municipal water supplies and thus require carbon pre-filtration.
Reverse osmosis water treatment systems are one of the most complicated types of systems on the market today and require pre-filters, storage tanks, pumps, drain connections and diligent attention to maintenance and testing.
According to the World Health Organization, low TDS or demineralized water produced by reverse osmosis or distillation is not suitable for long term human consumption and in fact, can create negative health affects to those consuming it.
What then is the best water filter for your home or office?
In our opinion, the best technology for home or office applications served by municipal water utilities is a combination of high quality carbon and sub-micron filtration.
Simple installation,
Dedicated faucet, (take back your fridge!)
Minimal maintenance
Visual filter change indicator and
Reduction of harmful contaminants to NSF/ANSI permissible limits, without removing healthy minerals.
