Puratek 100 GPD RO Filter System Information

Puratek 100GPD RO System

Procuring pure water rests at the very baseline of success for the modern aquarist. Vertex Aquaristik™ rises to this challenge with the conception of the Puratek RO water filter. Through sound component selection and optimization of contaminant extraction, Puratek RO units minimize water consumption and media replacement.


Puratek RO units all feature integrated manual backflush valves to maximize the life and output of the membrane cartridge. The unit is further furnished with an easily viewed oil-filled pressure gauge and an automatic shut-off valve which halts all water transit during instances of backpressure. A set of clear, easy-to-view canisters are unmistakably visible indicators of cartridge life. Finally, standardized fittings and cartridges remove all suppositions from installation and replacement routines.


  • ~1:2½ Pure/Waste water ratio (source water pressure & temperature dependant*)
  • Easy to view precision Oil-filled pressure gauge
  • Manual backflush system prevents TDS creep
  • High-pressure automatic shut-off valve
  • Tested at 60 PSI & 50°F source water


  • Footprint 13 ½" x 6"
  • Height 15 ½"
  • GE-100 GPD membrane
  • 5 µ polypropylene sediment cartridge
  • 0.5 µ carbon block cartridge
  • All ¼"push-connect fittings
  • Includes canister wrench and all installation adaptors and fittings

Comments: I recently decided to purchase the new puratek RO unit considering it was on sale and I figured what the heck. Upon opening the box and trying to get everything plugged into where it should be, I noticed that the instructions are useless. Considering I have no experience with RO units, it was pretty frustrating trying to get everything just right. However, after having done so, I found that the unit pumps out plenty of good clean water. It's quite shocking to see what the sediment filter alone takes out. Overall, once it gets set up, it's a great unit.

Comments: This r/o unit is solidly constructed with quality materials. It does perform very well even though I have not been able to accurately measure its output, it does work quickly. One gripe is the hardware that is sent with the purifier. I wish a hose adapter would be provided with it instead of the more complicated and involved "hard" installation kit. Fortunately I had one left over from the previous filter so I used it and was in business in no time. Otherwise this purifier delivers.
