Sink Water Filter
Are you looking for the best sink water filter? It's not as easy as it sounds, especially if you are not sure of what to look for in a sink water filter. Do not be overly concerned about the cost.
Many of the expensive units are not as effective as the lower priced models. It is all too easy to associate high price with high-quality, which in the case of sink water filters is far from the truth is.
The first thing to look for is what sort of water technology does the unit to work on. Not all technologies have the ability to remove all contaminants, some might be good at removing lindane or alachlor whilst others would have no effect on these pollutants. Reverse osmosis and distillation are two types of technology which were developed for industrial uses around 50 years ago.
Primarily for the photo and printing sectors which required mineral free water. Of course the systems of today are a far cry from those of long ago, but the principles are still the same. Reverse osmosis uses a membrane to remove pollutants based on molecular size, therefore different member's remove different contaminants.
It is a fairly slow system and requires pressure to push the water through the membrane. It needs 2 to 3 gallons of polluted water to produce a 1 gallon of purified water. It also lacks the ability to remove synthetic chemicals because of their molecular size. One of the most effective technologies that has emerged over the past few years is granular carbon or activated carbon. These are the most common countertop and under the sink systems.
The Environmental Protection Agency (EPA) has recognized activated carbon as the best technology for removing VOCs and THMs. The best sink water filter will comprise of three stages, activated carbon block, a sub- micron filtration unit and an ion exchange. Sub-micron pore structure is used to filter out sediment and cysts like Cryptosporidium, this has been responsible for numerous deaths in the past.
Another benefit is the removal of chlorine, it's amazing how much better your coffee tastes after chlorine has been removed. Another important item you need to check is the manufacturers data sheet.
This will tell you which contaminants and by what percentage they are removed. Some states such as CA and WI have laws governing the publishing of false or exaggerated claims. Any data that the manufacturers publish must be verifiable. Installing a good sink water filter is the perfect solution to your everyday water needs in addition to protecting the health of your family from waterborne diseases.
