Keep track of the volume of water passing through the BWT filters to ensure that the filters are replaced on time at the end of it's lifespan.
How to use:
1. Set the total volume of water corresponding to the filter size and water hardness level. (This table of values of found in all filter cartridge manuals)
2. The aquameter will begin counting down the moment water passes through.
3. Once the counter reaches zero or enters a negative value, it is an indication that the filter will need to be replaced.
