If you want to filter the water for your home, then you have quite a few options available. To help you narrow down your options, here are some different water filtration mechanisms and their respective benefits:
Treatment Unit Location
The first decision you need to make is where you want the filter to be. Specifically, do you want your filter to be located at the point of entry or point of use?
- Point of Entry - This specifically refers to the location where water actually enters your house from either a public water grid or a private water source. A point of entry unit will treat practically all of the water that enters your home and will likely not be visible in your daily life. This can be pretty convenient when everything is running smoothly, since the unit will be out of your way. On the other hand, if there is a problem with the treatment, then it might be a little more difficult to reach the unit, depending on where it is place.
- Point of Use - These units are more visible and are placed at locations where the water actually becomes usable, such as sinks or refrigerators. Some point of use units attach directly to the water source, while others require manual effort every time you want to treat the water, such as filtration pitchers. While point of use units can be a little more intrusive, maintaining their filters is usually a pretty simple process.
Next, you'll need to decide what kind of water treatment you actually want to use.
- Basic Filtration - The simplest type of filtration works by running the water through a porous membrane. The pores are big enough to let water through, but will trap most sediment and larger substances.
- Reverse Osmosis - Pressure is induced to force water across a membrane. The ultimate result is that the water will have low salt and mineral content, which may result in a fresher and clearer taste.
- Ultraviolet - By subjecting the water to UV rays, a wide range of bacteria will be killed. If you worry about dangerous water and don't care too much about the taste of minerals, then a UV filtration system might be for you. Of course, you can also pair a UV system with another filtration device to utilize the benefits of both.
- Softeners - If you want to reduce the hardness of your water, then you want a water softener to eliminate the calcium and magnesium that naturally build up in some pipes.
