No the bottles uses a spe pem membrane method so it will not allow the pH influencing gases through it, just h2

Good question! The carbon can be crushed and disposed with your garden waste or can be added to flower beds (it will improve soil drainage and will slowly biodegrade); the plastic cups can be disposed in the recycling bin.

We don't stock filter logic big blue housings so I am not sure if those will be exactly the same configuration as ours, if the housing is not standard then the filter may not be compatible. The carbon filter does not just provide sediment filtration to 5 micron it will also provide chlorine reduction improving the odour and taste of the water. If your water is filtered then stored in a tank it is recommended to install a pre filter and UV system after the tank as chlorine reduction will remove the microbiological protection from the water that is being stored.
