Water softeners work somewhat like a chemical magnet. However, all the water softener has done is remove calcium from your water and replace it with salt. This water is no safer than hard tap water. A high quality water filter does more than remove the calcium from your drinking water.

It will filter out 99.9999% of waterborne bacteria and 99.9% of waterborne protozoa. Chemicals, salt water, heavy metals and viruses will not be removed. If you are looking for a high capacity filter to remove viruses, the LifeStraw Mission and LifeStraw Family 1.0 remove 99.999% of viruses.
