Quality Water Filters 4 You Posting Page
Tuesday, April 13, 2010

In order to understand the importance of shower head water filters, it is important to first understand what is in the water prior to filtering.

Most city water systems add chlorine to their post-treatment water in order to keep the water in the distribution system disinfected. By Federal regulation they have to do this. They have no choice. This residual chlorine is crucial to keeping your water free of many harmful organisms as well as other nuisance issues such as odors, slime bacteria, etc as it travels through the system (water pipes). Once the water reaches your home, however, this added chlorine is no longer needed and should be removed before drinking the water or showering in the water. Here is why:

The basic chemical Chlorine changes as it comes into contact with materials that it disinfects. As these changes take place, new forms of the base chemical are formed. These are often called chlorine by-products. There is no way to stop this reaction from happening. It is the natural process for chlorine, and that is that.

Two of the by-products that consumers should be aware of are THM's (Trihalomethanes) and VOC's (Volatile Organic Compounds). Of these two, THM's can be especially worrisome as they fall under the Cancer Group B category. This means that they have already be shown to cause cancer in laboratory animals.

Well-run water treatment plants will try to minimize the levels of THM's and VOC's by monitoring the system and using only as much chlorine as is needed or required by law in the distribution system. Still, it is important to remember that their best efforts cannot eliminate all of the THM's and VOC's that come into your home via your tap water.

Quality shower head water filters will catch these harmful compounds before they are forced out through the shower head. It has been suggested by many experts that consumers get as much exposure to THM's and VOC's from showering as they do from drinking unfiltered water. One very important difference to keep in mind, however, is that shower head THM's and VOC's are normally inhaled into the lungs, while drinking them is a matter of ingestion into the stomach. Either way, the less of these contaminants you are exposed to, the healthier you and your family will be.
When shopping for a shower head water filter, try to find those that do the best job. You can find filters that are effective in removing 90 percent of chlorine, 90 percent of VOC's and THM's as well as other contaminants not mentioned in this piece. For best results look for shower head filters that deliver around 2.5 gallons per minute.
