My friend has a Reverse Osmosis filtering system. How does reverse osmosis and Berkey purifier systems compare? Are Berkey Better then Reverse Osmosis?

Reverse Osmosis uses a membrane which removes many contaminants from the water. It is usually paired with a Granulated Activated Charcoal filter to remove chlorine and many mount under the sink usually.   

The semipermeable membrane separates many contaminates (which usually have a larger particle size that water) from the water and rejects a large amount of water in the process.

The result is a waste of several gallons of water for every gallon filtered and many naturally occurring minerals (including calcium and magnesium) are also removed from the water.    These minerals are NOT removed in Berkey systems and this minerals are Essential for our bodies. 

Most test results and comparison sites do recommend Berkey Filters as No1 filter system on the market today so Yes we recommend Berkey filters instead of Reverse osmosis as the Berkey gives you a perfectly clean and pure drinking water without taking any good minerals out.  


Carbon filters like Berkey are recognized by the EPA as the best option for removing chemicals like herbicides, pesticides, heavy metals VOCs and all harmful chemicals in our water..  High quality carbon block filters like Berkey will remove chemicals, pesticides, bacteria, fluoride (with PF2 Fluoride filter attachment), heavy metals, nitrate, nitrites and parasites while leaving the essential minerals in the water our body needs.. 

This Berkey filters are gravity based and can safely transform any type of water into safe drinking water including rain water, pond water.
