Countertop Filter for the “Green” Consumer

by Diane Cowan

Through the easy installation of a countertop filter, drinking water that tastes good and is safe can become available through taps. Along with countertop filters, diverter valves are available, which can be used to attach faucets with the filters. The countertop filter’s diverter valve can be used to replace the faucet aerator, in order to obtain clean tap water. A countertop filter can help clean cysts, volatile organic chemicals, lead, chlorine and by-products of chlorine, out of the water.

Magnesium, potassium and calcium are the minerals in water that are beneficial for health and taste good as well. These are not removed from the water by counter top water filters, even as the harmful substances are. The substances that are at times found in water supplied by municipalities and cause bad odor or taste, like by-products of algae, are also removed by counter top water filters. Savings can also be achieved through the use of counter top water filters, since those who tend to drink only bottled water can replace that with water cleaned by making use of the filter. A decanter can be used for bottling water, in combination with the filter.

In order to fit the kitchen faucet with a counter top water filter, a diverter valve has to be fitted in place of the part where the water emerges from the screen i.e. the standard aerator. In this manner, the kitchen faucet provides water for the counter top water filter. For washing dishes in the sink or for drinking, water can be diverted via the filter, by pulling the handle of the valve. However, a counter top water filter may not fit, if a faucet of the pull-out sprayer type is being used.

Regarding the water filter’s placement at the faucet, there are different countertop filters available in the market, with different designs. A design that makes the output of water available at the water filter’s housing and a design that makes the output of water available at the kitchen faucet are among these. Before a purchase is made and before the most appropriate design choice is decided upon, a careful analysis of his or her needs can be carried out by the customer.

The countertop filter that is in use should, in a dependable manner, remove contaminants from the water. The time that an individual is able to spare from his or her lifestyle is also a factor upon which the kind of water filter in use may depend. Relatively maintenance free countertop filters may be sought to be acquired by those who find themselves hard-pressed for time.

In order for operations to continue, cartridge replacements are not required by the products with a carbon granule filter. In terms of better-graded and improved cartridge pore structure or in terms of more effective cartridges replacing less effective ones, especially in terms of the materials used for their production, technological advances’ benefit may not reach those who use filters of that kind, however.

Those who purchase the relatively maintenance free counter top water filters obviously stand to benefit from the longer life of the cartridge. However, there are certain things that those who wish to purchase a counter top water filter should look at carefully, before buying one. Mechanical filtration should be possible with such a filter. Fickian diffusion is utilized by mechanical filtration. When the fibers are moistened by the passage of water, contaminants are absorbed on account of diffusion.

Electrokinetic absorption should also be performed by a counter top water filter, in order to be effective. An electric field is produced by the particles in the water that are unwanted. That field is made use of by a counter top water filter that can carry out electrokinetic absorption. Additionally, physical absorption should be carried out by a good counter top water filter. Micron filtration and ion exchange is carried out by the activated carbon filters in advanced countertop filters.
