Unlike large point of entry water filtration systems, a water filtering faucet treats the water at one particular sink or other outlet. These types of faucets typically employ carbon filters that effectively remove many gasses and particles suspended in the water as it moves through the filter.
Just like any other type of water filtration system, there are various types of water filtering faucets and they are not all equally effective at removing contaminants. Before you purchase anything like this, however, you should make sure you know exactly what contaminants are present in your water. This is the only way to ensure that you purchase a product designed to treat exactly the problem that you have.
If you do decide to go with a water filtering faucet, make sure you know how often to replace the filters inside it and what type of replacements to get. Your water filter will only work properly when it is correctly maintained, and there is no point in using it if you have not been able to keep up with proper filter maintenance and replacement.
Another nice feature of water filtering faucets is that you can usually switch them on and off. When you need water for cooking or drinking, you can send it through the filter, and when you are using water for other things, you do not need to use the filter at all. This can cause the filter to last longer and it is also more convenient on models that have a reduced water pressure when the filter is employed.
You may initially balk at the cost of a water filtering faucet, preferring to purchase bottled water for drinking instead. But you have to take into account the fact that once you purchase a water filtering faucet, you will not have to spend the money on bottled drinking water any more. This will translate into a significant savings over time, making the initial investment well worth it in the end.
