IMPORTANT NOTE ABOUT
"TDS METERS" AND TESTERS
Q: When I use a Total Dissolved Particle (TDS) reader to test my water after it goes through the Capella,
why don't the levels of dissolved particles go down or decrease? I don't think the product is working.
Generally, Reverse Osmosis systems lower TDS readings by as much as 90% when compared to
tap water readings. This is a normal working range. For example, if your tap water TDS reading
is 100, then a normal TDS reading for the RO filtered water is in the range of 0–10. If the TDS
reading for the RO filtered water is higher than 15% of normal tap water, this indicates it's time for
a filter change, including RO membrane.
