TEST RESULTS - TOTAL DISSOLVED SOLIDS

    Before I move to my results I need to point out that the more you filter the water in the reservoir the “dirtier” water gets back in it (make sure you dispose remaining water in the end) and so even though initial PPM for fresh water was 172 according to the internal TDS sensor this increased as the water level decreased (last pass detected 297PPM).

    So, time to measure PPM with the AP-1 (153PPM for fresh water, 8PPM for water inside the pitcher). Do keep in mind that water is slightly remineralizer which is why you don't see 3PPM as the internal sensor (for people looking to get higher levels of remineralization - and perhaps improved taste - JIMMY will be releasing a new filter that boosts PPM to around 20).
