Hi all,
I need help! I have been involved in a discussion/argument about carbon filtration... I need to confirm that I am right (or wrong) in this discussion. I am not a chemist, unfortunately...
I really hope that Clive will see this post and will put things right as I am curious as well.
I bought a filter on Ebay – just activated carbon filter for home use - not that much for my aquariums but just for boiling the kettle for a cup of tea. Being what I am, I decided to use my TDS meter to see if the filtered water is any different from the tap water... And here it goes: tap water – TDS 173, filtered water – TDS 190. In my naivety, I thought that filters are there for, ermmm, filtering – so, the TDS would be lower in the filtered water. So, I sent a message to the seller on Ebay saying that I am not quite seeing the advantage of using the filter. They came back with a long-winded explanation that the filter is still working... My reaction was : ?????? I presume that pure H2O is just H2O, and anything dissolved in water increases TDS... So, I said this to that Ebay seller. However, they insist that the filter is still “filtering” (e.g. removing contaminants) even when the TDS meter cannot register this. Is this correct? (I omitted posting exact conversations with the Ebay seller – just to save time and space).
Am I right in thinking that this particular filter is useless in removing Chlorine and organic compounds or is the Ebay supplier right and I am totally wrong?
