The SpiroPure SP-RO300AQ 3-Stage Countertop Reverse Osmosis Water Filtration System includes sediment, carbon block, and reverse osmosis in one countertop RO system. This versatile, portable RO system can be set up on a countertop or mounted to the wall, for easy access to RO water, perfect for countertop and apartment RO purposes. The system requires minimal assembly with pre-installed quick-connect fittings and two faucet adapters to fit most standard faucets and hoses. Reverse osmosis filtration provides practically purified water that makes a great choice for drinking water, CPAP Machines, RV, humidifiers, baby formula, neti-pots, cooking and food preparation, and more.
3-Stage Countertop RO Water Filter System
- Stage 1: a 25 micron sediment filter employs premium polypropylene media to reduce dirt, rust, and other sediment particles from your water to protect your RO system
- Stage 2: a coconut shell solid block carbon filter uses activated carbon media to reduce chlorine and other chemicals before they reach your RO membrane
- Stage 3: a thin-film composite RO membrane filters over 1,000 impurities and total dissolved solids (TDS) down to 0.0001 micron for high-flow water filtration

I have the SP-RO300AQ RO filter system, and after the first two stages (sediment and carbon) the PPM of the water rises. After the RO stage, it drops as expected, but not as much as I thought. Is the system defective?
PPM is a measurement of the TDS (total dissolved solids) inside of the water. Sediment filters are designed to remove large sediment particles, and carbon filters absorb chemical impurities from water (such as chlorine), and are not designed to filter or reduce TDS at all. In fact, a new carbon filter will increase the PPM of TDS in water as it sheds carbon fines, but this should reduce after a couple of days of use. This is why it is recommended that you flush a new carbon filter, particularly if it is before an RO cartridge as it can cause premature fouling of the RO media. RO membranes, however, are designed to reduce TDS from water, and TDS meters are designed specifically to measure TDS reduction after more in-depth filtration like that provided by RO membranes. After a few days of use and once the carbon fines have all been flushed from the carbon filter, the TDS readings should be at a more desirable level after the RO membrane.
