On average, the human body consists of 60%-70% water, most of which is contained in the cells which need water to live. This expresses the importance of water. A lot of minerals naturally exist in water and are important for the human body. To acquire pure and clean water, water purifiers have become a necessity in the modern world. Many bottled water industries have been capitalizing the use of tap water since years, but tap water has always proven to be a better alternative to others. A good water purifier removes the excess salts, suspended particles and microbes and retains its essential vitamins and minerals. With many manufacturers and tough competition in the purifier industry, it has become a difficult task to choose between the many options!
The water filters and water purifiers work on the same functionary principle. They work by sucking up and extracting first, the raw materials and unwanted waste and then filter out impurities ranging from sediments to micro-organisms and then dispense clean water.
The big distinctive point between the two is that the water purifiers can even filter out the viruses and bacterial content in the water.

Under Sink Water Purifier Buying Guide
How Under Sink Water Purifier works
The major additional feature of an under sink purifier is that they sanction the use of multiple filters which help in achieving numerous objectives.
Activated carbon filtration, usually in the form of extreme performance carbon block filters, is the keystone of most under sink filters. All under sink filters must get a hands-on at least one good activated carbon filter. A golden thumb rule when choosing an under-sink filter is “the more carbon, the better.”
Water purification is the process of extracting unwanted chemicals, biological contaminants, suspended solids and gases from water. The main goal is to generate water, fit for specific purposes. Since clean and hygienic water is not easily available in most of the countries, purification may also be carried out for a variety of other purposes, including medical, pharmacological, chemical, and industrial applications.
Water purification process, to a large extent, reduces the concentration of particulate matter suspended particles, parasites, bacteria, algae, viruses, fungi as well as lower the concentration range of dissolved matter present in the water.
Advantages of Under Sink Water Purifier
1. Improve the Taste of Water
Depending upon the content of chlorine and fluoride or the surrounding in which one lives, the tap water may contain some unpleasant taste and smell. The lucky ones amongst us may feel weird reading this, but the unpleasant taste and odour of tap water shift many of us from drinking tap water to bottled water or to just drink less water than the body’s requirement. A good under sink water filter can easily fix all that.
2. No additional space require
Under sink water filters possess an edge when compared to countertop water filters. Space becomes a major drawback when one thinks of installing a water purifier. But an under counter water purifier does not require any additional space. One can fix the purifier on a wall or in a much convenient place. They might consume some space under the sink, but that becomes more economical than spending bucks on fixing countertop purifiers.
Under sink water filters are also exceptionally cost-efficient. They can save a lot on the amount one may spend buying bottled water every month! They are generally more efficient than other variants of water filters like faucet filters or freezer filters. However, it depends on the quality of the brand and the model, as well. The promoted benefits and the improvisation in health are quite noticeable and compensate for the price one pays, making it a money worthy product.
(Note: Simple under sink water filters are less efficient than conventional under sink water filters because they filter all variations of drinking water and not just the cold water)
Disadvantages of Under Sink Water Purifier
Tap is an essential requirement of any kitchen water purifier. The water may pass only if there is a faucet set attached along with the purifier. One may have to purchase a faucet set if not provided with the purifier.
External installation in the system may not prove to be durable and on the contrary, may also require extra expenditure.
The installation also requires an electric wall socket beneath the sink. Look out for a way to install this socket underneath so that the motor gets fixed easily without grabbing extra space.
To avoid any mishap, leakage proofing is essential. This again asks for some extra spending.
If not installed properly, the drainage system may fail its purpose and may cause leakage of the waste. Therefore, a certified technician may be required to fix the pipeline and installation of the filter.
A TDS controller helps to keep a quality check upon the number of minerals present in the water. Not having a TDS controller may result as a major drawback.
