When it comes to removing lead from your water, there are lots of different options. You can go with filtration types ranging from simple pitchers to in-line systems that hook right up to your water lines. Each of these systems is equally effective at removing lead from water, but are not effective for the same amount of time. For instance, in-line systems will last for a much longer amount of time than a pitcher, which makes them more effective over time.
If you want to make sure that you are removing as much lead as possible, for as long as possible, then it is a good idea to go with a system you hook up to your water source, as they have a much longer lifespan than smaller systems.
