Different Types of Water Filters

Water filters are not required in nature. Water reaches the planet in the form of precipitation and then moves along it in the way of streams of various sizes. Minerals that are crucial for life are absorbed by the water along the path. These minerals are absorbed when living beings drink the water. Ultimately, the water returns to the earth and goes on to the sea, from where it vaporizes and the cycle continues.

Whether in the form of raindrops or snowflakes, the water that falls down is pure. However, due to contamination by industries, storage of water in a centralized manner and other such reasons, it becomes difficult to find pure water and so water filters are required. In order to be useful to humans, water should be amenable to absorption.

Water filters are of different types, since the problems related to purification of water are different and require solutions that are different, as well.

Carbon Filters: These perform filtration's basic functions and are not very expensive. The installation of these filters is also rather easy. When water is moved through these, the contamination are absorbed. The husk obtained from coconuts provides them method for filtration in the form of charcoal medium carbon for some of these water filters. Despite that, these can clean out some of the most dangerous contaminants. Six to nine months is the duration for which an average carbon filter can be used effectively. Enhancement of its effectiveness can be achieved through the use of activated nano-silver.

These filters allow essential minerals to pass through, even as these stop a large number of contaminants from going across. deposit pre-filters may be required to be attached separately, in areas where large quantities of deposits are found in the water. Acidic contents in the water can not be rectified by such filters. Mold infestations have to be watched out against.

Distillation-based Water Filters: Impurities of all kinds can be cleaned out of the water through the process of distillation. This is in accordance with the belief that organisms that may harm the body are least likely to enter it through the purest form of water. For a long time that was thought of as being the best kind of water for the purpose of drinking. A distiller of the typical type, however, produces results that can be somewhat acidic.

Also, since there are no minerals to be found in distilled water, the balance of essential minerals in the body can also be impacted by drinking such water only. Along with the purity of water, the minerals that are found dissolved in water in its natural form are also significant and that is being increasingly realized by people nowadays. The metabolism and the immune reaction of the body is supported by such minerals and, therefore, these have a essential function to perform.

Ceramic Filters: A filter that can be fitted on top of a bench is generally fitted with a ceramic water filter. Algae that have been found in the watery portion of the earth for more than a hundred and fifty million years and are known as diatoms have left small-sized shells composed of silicon. These shells form a fossil substance known as Diatomaceous Earth, which forms an integral part of a ceramic filter. The outer shell of a ceramic filter, which is porous, is often impregnated with nano-silver, to protect the users of the filter against a number of bacteria.

Water Filtration founded on Reverse Osmosis: A fine membrane is used in these, for the filtration of water. Contaminated water is made drinkable in this manner. The process of osmosis is reversed in such water filters, after being stopped, when pressure is applied after putting unfiltered water on one of the membrane's sides. The water obtained after the process is very clean, even as the process is rather long drawn-out.
