It's important to note that if you have a private well, you should have testing done to see if you have bacteria that will require a disinfection stage. Now, it is possible to buy a UV light disinfection system for your home. At one time, you had to use chlorine.
If you are serviced by a public treatment facility, the only microbes you have to worry about are cryptosporidium and giardia cysts. A high quality water filtration device that includes a micron filter will remove them. Cysts cause waterborne illnesses. The symptoms are sometimes mild, but it can be fatal in people with compromised immune systems.
The equipment utilized at the water treatment facilities would be considered low quality water filters. The most common system used is reverse osmosis filtration system, which forces water through a porous membrane filter in order to remove contamination.
The reason that I call this a low quality water filtration system is because the primary use of RO is de-mineralization of water for industrial purposes. It is better suited for preventing mineral build-up in industrial machinery such as boilers than it is for cleaning drinking water.
The major problem lies in the fact that the porous membrane filter is incapable of removing any contaminant of the same molecular weight or less than the water that carries it. This means that any liquids or microbial contaminants are allowed to pass on to the household of the consumer. How could a system that does so little ever be considered anything except low quality water filters?
Once you get rid of the microbes, you have three primary types of contaminants. They are chemical compounds, gases and metallic ions. Examples of chemicals include chlorine, pesticides, herbicides, prescription drugs and specific compounds like benzene and perchlorate.
Quality water filtration remove chemicals and gases with granulated carbon and other media through a process called adsorption. Adsorption is a process where a gas or liquid accumulates to form a film of molecules or atoms on the surface of a porous material. So, these elements form a direct buffer between these liquids contaminants and your tap.
When attempting to rid yourself of the effects of toxic heavy metals you need to employ ion exchange technology. Ion exchange is a process where there is an exchange of ions between two electrolytes (minerals). It can also be an exchange between an electrolyte and a metal. Quality water filters will almost always offer you this option.
You can get the kind of protection that you need if you take the time to seek out the best filters for the task at hand. There are at least two that I can think of that will offer you every line of defense that we have covered here today. You don't have to settle for low quality water filtration anymore.
