WARNING: Do not drink water that has been treated with a deionization (DI) resin cartridge.
The SpiroPure SP-RO400AQD 4-Stage Countertop Reverse Osmosis Water Filteration System with DI Filter includes sediment, carbon block, reverse osmosis, and color-changing mixed-bed deionization 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 with DI filtration provides practically purified water with little to no TDS (total dissolved solids) that makes a great choice for aquariums, CPAP Machines, humidifiers, spot-free cleaning (cars, windows, glass, etc), and more.
4-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
- Stage 4: a DI filter with mixed bed color-changing resin media for enhanced filtration of ions from water, including sodium, sulfate, copper, and more. The color changing resin changes from green to purple letting you know when it is time for a cartridge changeout.

I have the SP-RO400AQD RO/DI filter system and used a TDS meter. After the first two stages (sediment and carbon) the PPM of the water rises, and after the RO stage, it drops as expected. But then after the final DI stage, the PPM rises once more. Is the filter 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 or DI cartridge as it can cause premature fouling of the RO or DI 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. Deionization (DI) can then provide further reduction of TDS from water. To see the desired results, we recommend using the filter system without the DI cartridge for a few days when first using the system or after replacing the carbon filter to ensure the carbon fines are gone. After that, reintroducing the DI cartridge should reduce the amount of TDS even further after the RO membrane filtration.
