SpectraPure® SilicaBuster™ Super DI™ Multi-Layer De-Ionization Cartridges are fabricated with the highest
grade custom-blended resins for ultra-pure water. They are capable of producing 18 meg ohm-cm
resistivity water. They are the first de-ionization cartridges designed to reduce silica, nitrates and phosphate
levels into the low ppb range. These newly formulated cartridges far exceed the performance of
previous cartridges, offering enhanced contaminant removal, longer life and higher purity. This cartridge
needs resistivity or TDS monitoring to determine when it is exhausted.
Caution: The de-ionization cartridge life is greatly reduced when operated on low pH waters or water
with high CO2 (carbon dioxide) levels. The exact cartridge life will vary greatly with pH, carbon dioxide
levels, TDS, etc., in your RO water or the feed water supplying the RO system. Aeration or de-gasification
of RO product water is recommended for such waters for removal of carbon dioxide.
33% more removal capacity than our standard Silica-
Buster™ DI cartridge
Proprietary High Flow, Low Pressure Drop cartridge

Highest silica, nitrate, phosphate, and heavy metal
removal of any 10" DI cartridge available
For ultra high purity water (18 meg ohm-cm resistivity)
Highest grade, custom-blended resins used for highest

Aluminized mylar packaging eliminates DI cartridge
degradation during storage.
Optimized for post-RO or post-distillation filtration

remaining capacity without metering.

I have been packing my DI and burning it very quickly, ICP shows I had Silicon in my water, with this DI after 6 months still holding strong and ICP shows undetectable levels of silicon.
Easy install, works well, and is a great price. I'm getting 0 tds with this and other filters purchased from MD. Having a color indicating cartridge is very helpful.
I can always tell when my DI filter is exhausted as my TDS will start going up. Our water from the tap is about 380ppm. After RO/DI it is usually less than 4ppm. When the DI quits working it will climb to about 40-45 as that's what the RO unit puts out.

I can always tell when my DI filter is exhausted as my TDS will start going up. Our water from the tap is about 380ppm. After RO/DI it is usually less than 4ppm. When the DI quits working it will climb to about 40-45 as that's what the RO unit puts out.
My only complaint is they don't last very long. I believe that is because there is quite a bit of time between water making sessions, so water sits in the cartridge for up to a couple of weeks while I use the water from the storage barrel.
Good product though, easy to see the color change and indicate it's used up. Definitely get a TDS meter though be sure.Hide
