Sizing Guide

Model Number of Bathrooms in Home Flow Rate* Backwash Flow Rate Dimensions
0.75 CF 1 - 2 8 GPM 5 GPM Diameter: 8" Height: 51.5"
1.0 CF 1 - 2 10 GPM 7 GPM Diameter: 9" Height: 55.5"
1.5 CF* 1 - 2 12 GPM 10 GPM Diameter: 10" Height: 61.5"
2.0 CF 2 - 3 14 GPM 12 GPM Diameter: 12" Height: 59.5 "
2.5 CF 2 - 4 15 GPM 14 GPM Diameter: 13" Height: 61.5"
3.0 CF 2 - 5 20 GPM 18 GPM Diameter: 14" Height: 72.5 "

Flow Rate: Refers to maximum recommended Gallons Per Minute ("GPM") which means how fast the water is flowing. The 1.5 CF model works best for most homes (such as 2 -3 bathroom homes with 2 - 6 persons). However for homes with 2 - 4 persons, the 0.75 or 1.0 CF models work great. Higher flow rates are possible through these systems, this is just meant as a guide or suggested use.

Have Questions? Call 888-600-5426 and speak to one of our certified water treatment technicians for technical help or if you have questions about sizing or flow rates.

Removal Rate: Removes up to 30 PPM iron, 15 PPM manganese, 10 PPM hydrogen sulfide (optional chlorine feed may be needed for extremely bad water).

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

Manganese removal: when manganese is present, 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 on removing manganese. A carbon filter can be used after the Pro-OX system to remove any residual chlorine.

Hydrogen Sulfide Rotten Egg: if hydrogen sulfide is present and the water also contains iron, we recommend an Air-Charger Pro-OX system. If the hydrogen sulfide levels are over 5 PPM, we recommend a chlorine feed, and/or aeration prior to the Pro-OX system. Please contact us for more information if you need assistance.

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

  • 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.
  • System automatically backwashes based on days (time clock version) OR with the optional Backwash On-Demand Flow Sensor. Reliable heavy-duty NSF certified control valve is easier to program than other valves and features an optional built-in flow sensor that tracks water usage and backwashes iron filter based on gallons used, and/or by days of the week!
  • Backwash Flow Rate and Quantity: uses 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. Removes up to 30 PPM iron and 15 PPM manganese. Higher levels possible with injecting air, chlorine or hydrogen peroxide ahead of filter. 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, 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.
  • Filter tank is 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 rinse cycles saving water and allowing maximized performance.
  • Time-tested hydraulically balanced piston seal and spacers provide years of trouble-free service.
  • Non-corrosive high-tech material construction.
