Iron & Manganese Filters
Pro-OX Lite is a manganese dioxide filter media made in Texas. It catches iron and manganese with no chemicals to add: no permanganate, no salt, just an automatic backwash. It's light, so it backwashes clean on a home well. Choose the valve that fits your home: 5900-BT, Rev4 or 7500-M.
- Remove Iron & Manganese
- Add AIR or ozone for sulfur odor.
- No more rust staining!
Which Pro-OX Lite Iron Filter to Choose?
All three use the same Pro-OX Lite media and tanks. The difference is the control valve on top.
The backwash flow your well must supply depends on the tank size, not the valve. Check the sizing guide on each page.
Optional Add-ons
Air Charger (AIR)
Helps with sulfur odor and manganese
Choose AIR in the options on the 5900-BT or Rev4 filter page.
We recommend the Air Charger add-on if you have manganese or sulfur odors (rotten egg smell) along with iron. The Air option allows the water to be aerated, which helps remove sulfur odor and gives you increased oxidation.
Ozone
For stronger sulfur odor and iron bacteria
Choose ozone in the options on the Rev4 filter page.
The ozone upgrade injects ozone gas in the air cycle instead of plain air. This helps reduce iron and sulfur bacteria, gives much stronger oxidation for sulfur odor, and helps the Pro-OX Lite media remove higher levels of iron and manganese.
The generator has a built-in air dryer and produces 1 gram of ozone per hour.
J-PRO-38 Chlorine/Peroxide Pump
For iron bacteria and severe sulfur odor
We recommend a J-PRO-38 if your water has iron bacteria, severe sulfur odors (hydrogen sulfide), or unusually high iron or manganese levels. It injects chlorine or hydrogen peroxide into the water before it reaches the filter.
Considering hydrogen peroxide for sulfur odor? We recommend a contact tank after the peroxide injection, then a catalytic carbon filter ahead of the iron filter to remove leftover peroxide.
Our water treatment specialists can help determine if a J-PRO-38 system is recommended based on your water test results.

Frequently Asked Questions
The spindown filter removes sand or grit that may be in your well water. Keeping sand out protects the filter media and the control valve, whichever valve you choose.
Another advantage is that it can be used to sanitize your Pro-OX Lite iron filter with chlorine bleach if you have iron bacteria. By adding a cup of bleach once a year to the spindown filter, and turning the water back on, the Pro-OX Lite media can be cleaned and sanitized. It only takes a few minutes and no chlorine gets in the house, as the filter is then put into backwash after sanitizing.
We recommend the Air Charger add-on if you have manganese or sulfur odors (rotten egg smell) along with iron. The Air option allows the water to be aerated, which helps remove sulfur odor and gives you increased oxidation.
Air is available on the 5900-BT (1.0 CF and up, +$150; not on 13x30 short tanks) and the Rev4 (0.75 CF and up; not on 13x30 short tanks). The 7500-M has no air option.
We recommend a J-PRO-38 if your water has iron bacteria, severe sulfur odors (hydrogen sulfide), or unusually high iron/manganese levels. The J-PRO-38 can inject either chlorine or hydrogen peroxide into the water before it reaches the filter.
This pre-treatment helps control iron and sulfur bacteria and oxidizes dissolved iron, manganese and hydrogen sulfide gas, so the Pro-OX Lite filter can handle tougher water.
Considering hydrogen peroxide for sulfur odor? We recommend a contact tank after the peroxide injection, then a catalytic carbon filter ahead of the iron filter to remove leftover peroxide.

Most of our customers do install themselves, however it is easy for any plumber or handyman to install. Ordering the optional flex lines makes it very easy to hook up to your piping.
The 5900-BT and Rev4 include a bypass valve. The 7500-M doesn't; plumb a simple 3-ball-valve bypass (inlet, outlet, bypass).
It depends on the valve. The Rev4 and 7500-M use a ceramic-disc valve that needs very little routine maintenance. The 5900-BT uses a standard piston and seals that you can service yourself with simple tools.
If you add AIR: on the Rev4, clean the air injector once or twice a year (about 10 minutes, no special tools). On the 5900-BT AIR, clean the injector screen and replace the piston seals once a year.
There is little or no maintenance required. If your water has iron bacteria you can add some chlorine bleach in the optional spindown filter, turn the water back on and clean the Pro-OX Lite media with chlorine once or twice a year. This removes any iron bacteria film and restores the media. Many customers go years with no maintenance. Customers report many years of service, and when the media is finally spent it's easy to replace.
At the maximum flow rate, expect about a 15 psi pressure drop; at normal household use it's less.
Your well produces a maximum amount of gpm. Many wells are less than 10 gpm, and you size the filter to match your available flow rate.
If you have a submersible pump with a pressure tank and switch, use this link to find your available flow rate.
