Pro-OX 5900-BT Series

Pro-OX Iron Filter 5900-BT

"I installed the filter system myself. Installation of the Pro-OX 5900-BT Iron Filter went smoothly and the filter has been in place for almost 2 weeks. I also placed an inline chlorinator and contact tank upstream. ... There have been no rusty deposits in the toilet since installation. So far the system is performing well. The people at Clean Water Store were very helpful and responded quickly to questions."

Sizing Guide

Model Number of Bathrooms in Home Flow Rate Backwash Flow Rate Dimensions
0.5 CF 1 6 GPM 4 GPM Diameter: 6" Height: 42"
0.75 CF 1 - 2 8 GPM 5 GPM Diameter: 8" Height: 51.5"
1.0 CF 1 - 2.5 10 GPM 7 GPM Diameter: 9" Height: 55.5"
1.5 CF 1 - 3 12 GPM 10 GPM Diameter: 10" Height: 61.5"

Flow Rate: Refers to the maximum recommended Gallons Per Minute ("GPM") which means how fast the water is flowing. The 1.0 CF model works best for most homes. However, for homes with 2 - 4 persons, the 0.75 or 1.0 CF models work great. 

Twin tank systems (such as installing two 1.0 CF models in parallel) are also a good option for peak high flow rates for large homes or higher use for irrigation or other higher water demands.

"CF" refers to the amount of filter media in cubic feet. A 1.5 CF has 1.5 cubic feet of Pro-OX iron filter media (Pro-OX, Zeolite and filter gravel).

Removal Rate: Removes up to 5 PPM iron, .5 PPM manganese (chlorine feed recommended for higher levels of iron or if sulfur odor present).

Iron levels over 5 PPM, or when manganese or other conditions such as low pH, high levels of sulfur odor,  iron bacteria or tannins, please note that additional treatment such as chlorine, peroxide, or aeration may be needed.

Manganese removal: when manganese is present especially if over 0.5 PPM, we recommend a chlorine feed. A chlorine feed with a contact/retention tank allowing 30 seconds of time after the chlorine has been injected, followed by the Pro-OX filter systems does a GREAT job of removing manganese. A carbon filter can be used after the Pro-OX system to remove any residual chlorine, so you get all the benefits of chlorination without having any chlorine in the house water.

Hydrogen Sulfide Rotten Egg Odors: if hydrogen sulfide is present and the water also contains iron,  we recommend a chlorine or hydrogen peroxide feed system.   

  • Pro-OX Filters are the longest lasting and most powerful system for removing iron, rust and sediment from well water.
  • Contains a unique blend of high-purity manganese dioxide (Pro-OX) and naturally mined Zeolite for filtration down to 3 microns for maximum filtration and iron removal.
  • Pro-OX Filters include pipe connectors; by-pass valve; filter gravel, Pro-OX Manganese Dioxide NSF Certified filter media; Zeolite Turbidity Filter media, filter gravel, filter tank; heavy-duty automatic backwash control valve.
  • The system automatically backwashes based on days (time clock version) OR with the optional Backwash On-Demand Flow Sensor.  
  • Control and monitor remotely with your phone with free Bluetooth app.
  • Backwash Flow Rate and Quantity: use 50 - 100 gallons of backwash water 1 to 3 times a week depending on water use. Compared to other iron filters, the Pro-OX filter uses 50% less! Safe for septic tanks.
  • Pro-OX Manganese Dioxide is an NSF Certified natural high purity mineral that is used for removing iron, hydrogen sulfide, and manganese from water supplies.   Iron bacteria, hydrogen sulfide and tannins can also be removed, contact us for more details.
  • Pro-OX media utilizes an oxidation-reduction reaction and filtration process similar to Greensand but at a much higher level of performance. It works much better than other solid manganese dioxide iron-filter media due to its higher purity and porosity.
  • Pro-OX Manganese Dioxide contains greater than 80% manganese dioxide in an extremely unique cluster format for enhanced performance and maximized capacity.
  • Pro-OX Manganese Dioxide generally works better than Greensand or Birm, due to its high purity, and superior oxidation/filtration ability. Unlike coated iron filter media such as Greensand or Birm or MTM, Pro-OX lasts for many years and doesn't have a coating to wear off or deteriorate like other iron filter media.
  • Note that in some waters aeration, hydrogen peroxide injection or chlorination is used before the iron filter to increase removal rates of iron, manganese and hydrogen sulfide.
  • The filter tank has NSF certified one-piece seamless polyester construction for long life.
  • Max pressure recommended is 100 psi.
  • Maximum water temperature recommended 100F.
  • Rugged heavy-duty automatic backwash control valve features fully adjustable backwash and rinses cycles saving water and allowing maximized performance.
  • Time-tested hydraulically balanced piston seals and spacers provide years of trouble-free service.
  • Non-corrosive high-tech material construction.
