If you are interested in cleaning up the water for your home, then there are quite a few different filtration systems for you to choose from. To help you figure out which option is best for you, here are some of the key decisions that you will need to make:
Point of Entry vs Point of Usage
The first decision that you need to make is whether you want all the water to be filtered by default or whether you want to set up filtration systems on an outlet-by-outlet basis.
Point of entry systems work by filtering all the water as it enters through your water main. This means that all of the water in your home is filtered, alleviating the stress of managing multiple filtration systems. However, this does come at a hefty cost, since it can be expensive to install point of entry systems. On top of that, they aren't always easy to access and you might have difficulty troubleshooting them if something does go wrong.
On the other hand, point of usage systems need to be set up at every water outlet that you want to filter. Some of these systems are passive, meaning that all the water flowing through a given outlet will be filtered before it comes out. Others are active, requiring your input and some effort every time that you wish to use them, such as portable water filters. It's pretty easy to maintain and fix these units, but you will need to handle many more units in total than if you were dealing with a point of entry unit (assuming you want to filter more than one outlet in your home).
You might also have different goals when it comes to filtering water. Different mechanisms are effective at removing different components from your water. Here are a couple of examples that can help you get a better idea of what each filter does.
Activated Carbon - These systems will remove a wide range of minerals and chemicals from your water, improving the taste substantially. However, they are not good at removing certain metals and salts. Sediment will also pass through activated carbon filters pretty easily, so you will need an additional filter if you want to remove the gritty texture that might pollute your water.
Reverse Osmosis - These systems use and pressure to force water through a membrane that has very small pores. The general idea is that the membrane should stop most of the larger particles in water, but it does have the obvious downside of not affecting smaller particles.
