Water filters cover the gambit from simple faucet filters, refrigerator filters, in-line filters to filter housings with a replaceable filter cartridge to all types of whole house backwashing / regenerating filtration systems that remove, iron, odors, manganese, radium, lead, turbidity and a plethora of other water problems.  This subject covers such a wide range of water problems it could take many blog articles to cover just the basics of water filtration.   One thing I know for certain though is what the typical consumer considers a water filter and what a water treatment professional would consider a water filter are totally different.
