I appreciate there are many water filters being used in the world, my question is there any particular one that can actually REMOVE ALL Bacteria. Most filters use chlorine after installation. Can you answer my question and tell me if any filter purifies and stops all bacteria ?

  There is no filter that completely removes all bacteria. That’s why filtration isn’t the only process to purify water. Filtrations gets rid of a lot of harmful organisms, but there is always going to be something that gets through. This is why water is disinfected and why we boil water for infants.

  I am currently writing a book on a related topic. My research has yeilded the following.

  Boiling, yes
  Chemical mehtods (like bleach as one example) yes
  Distilation yes
  reverse osmosis systems yes
  Glass, ceramic and carbon filtration no

  Of these 5 methods you may also like to know the following.
  The last three will remove volitile organic compounds
  the last 2 will remove mercury lead and PCBs.
  only the last one will remove chlorine.

  Also cemical methods are not very effective against protazoan cysts like cryptosporidium.

  Chemical methods include water purification tablets like globuline-tetraglycine gydroperiodide (potable aqua tablets)

  Iodine crystals

  and halazone tablets. If these have a bit of a funky smell they have gone bad and should not be used.

  There are some multi stage filters that use some combination of these steps. You may wish to look for one that employes the use of silver. Silver will kill bacteria. The multi stage filters are a pluse

  You can also use a multi stage process of your own…using chlorine to kill the critters and then using a carbon filter to get the chlorine out.

  The process would work like this. add 12 drops of bleach to a gallon of water. let stand 30 to 45 minutes. Then run it through your carbon filter.

  This is the recomendation I’m puttin in my book (its about surviving disasters and the things you will need to prepare)

  Hope this is of some use to you.
