One illustration of how many and how much pharmaceuticals in water have infiltrated our water supplies came from testing of fish caught in water downstream from sewage plants in five U.S. cities.  They all contained traces of many pharmaceuticals.  In the fish from one location, Chicago’s North Shore Channel, the breakdown showed:

• Dilitiazem, an antihypertensive – 0.13 nanograms per gram of fish
• Diphenhydramine, antihistamine – 1.4 nanograms per gram
• Carbamazepine, antiseizure – 2.3 nanograms per gram
• Norfluoxetine, an antidepressant by-product – 3.2 nanograms per gram of fish

Now a nano gram is a very tiny amount, and it is reported that you’d have to eat tons of such fish for such small concentrations to effect human health.  However, what happens if you drink the water with all these drugs in it?

Drug Residue Affecting Fish

What is in your water supply one day could vary a lot from what is there a month later.  How the chemicals and drugs in your water supply combine is simply unknown.  How can it be known exactly what a filter will remove when you don’t know what is in the water to begin with – and when it varies by variety and time and place and amount?

The best thing you can do is get filters for your home and family that work on all of the categories of contaminants. Pharmaceuticals in water are all either chemically-based or organic-based. In all of our kitchen and whole house filters, there is kdf that works on the chemically-based contaminants, including drugs, and granulated activated carbon that works on organically-based contaminants, including drugs (legal and illegal.) Kdf also increased the effectiveness of the carbon in a few ways: 1. Because of the patented-process used with kdf in these filters, the kdf takes up a lot less space to do a better job – allowing for more carbon. Filtration happens by contact time between water and filter materials. The patented process increases contact time so more chemical pharmaceuticals are removed. Having more carbon means more contact time so that organic pharmaceuticals are filtered. The net result is clean, healthy water.

We have chosen those water filters because we believe them to be the best – and for very good reasons.  While we have been offered the opportunity to sell several other lines, our preference is to offer only those that we consider the best and the best value. Please visit more pages within this Education section of our site to learn more about how people’s health has been enhanced by using these filters.

What About Reverse Osmosis?

We’ve don’t sell or recommend reverse osmosis for a number of reasons. Some say that reverse osmosis filters remove pharmaceuticals and other chemicals now found in our water supply.  The truth is: only partially.  Reverse osmosis works by separating water with contaminants from water without by passing it through membranes.  If the molecules of a drug or chemical are smaller than the membrane filters out, then they will pass through.  For example, synthetic pesticides and herbicides may not be filtered.  How many, which drugs, and which chemicals are filtered out?  How can one say when they are different all over?
