There are things that get into the water between the facility and your tap that only a good drinking water filter can remove.
Lead, for example, has been found in the tap water in many areas of the country.
The FDA says that anyone could have lead in the water and testing is a good idea.
It is one of the things that have nothing to do with the treatment facilities.
The problem is in the pipes.
Of the top ten brands of drinking water filters, all of them block lead.
If you always, use a drinking water filter, then you can avoid the expense of having your water tested for lead.
Apparently, microscopic organisms like cryptosporidium are another problem that cannot be addressed by municipal water treatment facilities.
The FDA advises that even the best facilities cannot positively remove cryptosporidium from the water.
Furthermore, they advise that there is no feasible way to test for its presence.
Drinking tap water contaminated with cryptosporidium caused the deaths of over 100 people in Milwaukee.
The outbreak led to stricter regulations concerning farm run-off near public water reservoirs, but the only way to be truly safe is to use drinking water filters with a micron filtration step.
A popular and highly advertised drinking water filter does not include micron filtration, so there is no protection from cryptosporidium.
When you compare drinking water filters, ask to see the performance data sheet and other certifications, before you buy.
The category that covers cryptosporidium and other microscopic bacteria is "cysts".
If you are ordering on-line, the manufacturer's website should offer the information, freely, prior to purchase.
If they don't, then choose another brand.
Most treatment facilities use chlorine to disinfect the water, killing bacteria, algae and other living organisms.
For some reason, cryptosporidium happens to be resistant to chlorine, as are other bacteria during the cyst stage.
But, supposedly, it's the best they can do.
The facilities add chlorine to protect your health, but drinking chlorinated water can cause health problems.
Activated carbon drinking water filters remove 99.
9% of the chlorine, improving the taste and making it safer to drink.
People have many different reasons for using a drinking water filter.
Concern for their personal health is one, but a growing number of people are concerned about the environmental impact of drinking bottled water.
Researchers are reporting that 80% of the plastic ends up in the landfills.
Companies are responding by using less plastic in the bottles.
The thing to remember is that bottled water is really just tap water.
If you invest in good drinking water filters, you can bottle your own at home, for a cost of pennies per day.
You'll be saving money and helping to protect the environment.
