In this article you'll read all the info you'll need before you buy an under-sink water filter. Water filters are actually housings, in which you place an activated carbon filter that reduces a bunch of harmful substances from your water. Depending on the quality and permeability of the carbon filter, these cartridges can reduce chlorine, heavy metals, Volatile organic chemicals etc.
First of all you need to decide if you need single, double or even triple filter. This depends of course on your water quality. If for example you only need to attack basic problems such as chlorine and bad taste and odor, then you should buy a single water filter. If you also have another problem such as hard water, then you should buy a double water filter (place a limescale reduction filter in the first stage and a carbon block in the second stage). For each problem you should add a housing. If for example you have bad taste and odor, hard water and nitrates, then you should buy a triple water filter - place a nitrates reduction filter in the first stage, a limescale reduction filter in the second stage and a carbon block in the third stage.
If you have more than 3 problems, then you should consider buying a reverse osmosis system. Reverse osmosis ( RO for short) is probably the best water treatment solution today. It produces water with zero conductivity, absolutely free of chemicals and limescale.
What's next? After you've decided how many housings you need (single, double or triple water filter), you now have to decide whether you need a seperate tap just for filtered water or an inline installation. Under sink water filters can be connected in 2 ways:

George Margiolos was born in Thessaloniki and has graduated from the Department of Marketing of the Alexandreio Technological Educational Institute of Thessaloniki. He is fluent in English and (not so fluent) in German.
Ηe has been Project Manager at Avery Dennison - Fastener Division in the UK. There, his main project was to redesign the company's products into new applications so as to become more environmentally friendly. In combination with the fact that in the UK people are more familiar with water filters, he has developed a love for environmentally friendly water filters, which reduce the use of plastic bottles and improving people's quality of life.
Since 2008, he has published over 300 unique educational and informative articles on water filters and new water treatment technologies.
Occasionally, universities and doctoral students request to use George Margiolos' articles in their research because of their quality and uniqueness.
