Water filtration and purification are ways to improve your health. When drinking a lot of water, especially from the tap, you should consider a filtration and purification system. While these seem very similar they are not necessarily interchangeable. A water filter system will simply filter out sediment, particulates, minerals, and other contaminates. A water purification system will be more like a reverse osmosis system that will actually purify the water itself. The water purification systems are much more technically advanced and perform better than a basic filter system. The water from an actual purification system will be even more healthy for you and your family as well. When you look at bottled water, you will see on the label, in small print no less, what the water source is and how its treated. You will see some are actual spring water that is filtered while in some cases of the popular brands you will find their sources to be city tap water then either filtered or filtered and purified. As technology grows, the better the water purification systems become. A purification system that is several years old will not be as efficient as a modern system. Keep this in mind as you shop for these types of systems. Some systems will be rated for lower productivity like the older models while the new ones may not interfere with water pressure or require near as much maintenance on the units either. A water filter and purification system combined is the best method, just ask a profession for their input on the systems.
