What is the difference between purification and filtration? PDF Print E-mail

Purification involves the process of physically separating the pure water molecules from the contaminants. This is a very slow process. The only 3 methods of water purification available today are distillation, reverse osmosis and de-ionisation.

Filtration is primarily designed to filter out only one or two specific contaminants: iron filters to remove iron, carbon filters to remove chlorine, sediment filters to remove solids, etc.

Many of your portable types of systems available from your drugstore, hardware, or dept. store are in fact only filters.

The easiest way to determine which is a purification system and which is a filtration system is to determine how long it takes to collect the drinking water. If it requires only seconds or minutes, this is a filtration system. If it requires many hours, it is a purification system.
