Osmio 4.5 x 20 Inch Carbon Block 5 Micron - All Questions

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.
