There is a lot of debate out there about water, and the best way to get a good source. Some say you should buy spring or distilled water, or filter it at home. Some people say that it makes no difference if you drink from the tap!
Tap water is free of microbes, but contains many toxic chemicals, including chlorine, which is very toxic to the body. It is especially important to avoid chemicals if you have cancer or other chronic diseases like Parkinson’s or Alzheimer disease.
It’s my understanding that the Pur filter is the best pitcher-style filter. It gets out chlorine, spores, and most of the chemicals from tap water. I have also heard that the best overall filter is the MultiPure (different company). They have a model which sits on the sink or fits under it.
I would say that at the minimum, any filter that gets out chlorine is necessary.
I think about the processing chemicals and pesticides in the water, and wonder what these filters can get out. The materials for MultiPure address this.
There has been some discussion that distilled water is by definition as pure as you can get. I have heard that none of the small chemicals from the source water can be present in distilled water by virtue of the distillation process. I am not sure that I am convinced of that. MultiPure says that the chemicals can recondense back into the distilled water. Also, because distilled water has no minerals, it may leach minerals out of your body- bone and tooth problems have been reported.

Whatever you choose, drink water every day! 64 ounces is an average recommendation. To help you remember, keep a water bottle with you. Some people find that having a straw encourages them to drink more. Others like bubbly or flavored water.
If you have kidney problems, 64 ounces per day may be too much for you.
