Some companies claim their water filters can produce truly pure water for drinking, but that statement is somewhat false.
No water filtration system produces absolutely pure water.
Some do decrease the number of contaminants to a greater degree. The very best water filtration systems tend to combine more than one type of technologies.
Let’s take a look at some water filter choices.
When shopping for the best water filters, select one which will reduce contaminants to at least 1 micron; much less if possible, as the smaller the number, the better the filtration. Too much filtering though and you will remove the minerals which are good for your bones and teeth. These units will typically combine several types of filters.
If you take a look at loose carbon filters, you’ll discover that they are really bacteria factories. They allow oxygen to exist within the filter, which encourages and magnifies the growth of bacteria. Even though this particular filter is very cheap to buy, it’s expensive over time, because the filters should be replaced often.
Distillation is effective when filtering bacteria, solids, sediments and organic or any chemical contaminants which will not evaporate. There are some chemical pollutants, such as MTBE, which will evaporate, so distillation isn’t efficient in filtering that.
Ultraviolet (UV) light is sometimes utilized as well as other filters to destroy bacteria, and has been discovered to be a very effective tool. The light affects an organism’s DNA, so it cannot replicate. If it can’t replicate, it’s benign.
Reverse osmosis (RO) is really a filter which lessens fluoride, radium and many other pollutants to a quite high degree, although it does have its limitations. There are a big number of contaminants found in water which will easily pass through an RO water filter. Reverse osmosis is also utilized in conjunction with other filters to be very efficient, though the procedure does get rid of the healthy minerals as well. RO by itself is capable of decreasing pollutants such as radium, arsenic, barium lead, nitrates and nitrites, and even giardia and selenium that are discovered in your drinking water.
The Berkey Light is the most advanced passive water purifier available. It removes pathogenic bacteria, cysts, chemicals including herbicides, pesticides, foul tastes and odors, and reduces heavy metals without removing the healthful and nutritional minerals your body needs.
How do you know if the claims made by the company are correct and true?
If the filters aren’t certified by the NSF, (the National Sanitation Foundation) then simply put it back on the shelf. Those manufacturers of quality water filtration systems put their filters via rigorous testing by the NSF and are proud to have their certification. NSF tests and certifies water treatment units to determine which the best water filters are for customers.
