Removes up to 15 ppm iron

Causes red/orange staining with levels as low as 0.3 ppm. Treats both ferrous (clear water or dissolved) and ferric (red water or oxidized) iron.

Removes up to 7 ppm hydrogen sulfide

The cause of rotten egg odor. Incorrectly referred to as sulfur most of the time.

Removes up to 3 ppm Manganese

Can cause black slime buildup in toilet tanks and may impart a metallic taste to the water

Dual Motors

Separate motors for piston control and timing ensures consistent, long lasting operation

3 GPM Service Flow

Treats a maximum flow rate of 3 gallons per minute

4.2-5.2 GPM Backwash Flow

Requires a minimum of 4.2 GPM for backwashing. 5.2 GPM is recommended for optimal system performance and media life.

Product Description

Iron is a common problem in homes today. It causes red staining on fixtures, as well as turning clothes and sometimes even your hair a reddish orange color. Iron bacteria is sometimes present in water with iron, creating a slimy build up in standing water (such as your toilet tank) and can smell like rotting vegetation. Hydrogen Sulfide (mistakenly called sulfur quite frequently) is easily detected by the presence of a "rotten egg" odor, and is sometimes associated with yellow staining. Manganese is most often seen as a black slimy substance that builds in standing water, and may impart a metallic taste to the water.

The Filox* system provides high contaminant removal with excellent service flow rates and reasonable backwash flow rates. Combined with chemical free performance and competitive pricing, the Filox* system is one of the most popular systems for treatment of iron, hydrogen sulfide, and manganese.

Controlled by the Fleck 2510SXT control head, this system automatically backwashes. The backwash process uses no chemicals, simply using the force of water to clean the media and flush the contaminates down the drain. Made by Fleck, the #1 manufacturer of control heads in the US, the digital control head provides LCD display and touchpad controls, allowing for simple, user-friendly interaction. The 2510 valve also offers dual drive motors, providing dedicated control for piston movement and system timing. This allows for stronger piston control, fewer parts (since there are no connecting gears required) and longer, more reliable operation.

Service Flows
Service flow rate is the manufacturers recommendation for maximum contaminant removal at a constant flow for media alone. Intermittent flow rate and/or lower contaminant levels MAY allow higher treatment flow rates.

Backwash Flow Rates
The backwash flow rate is the minimum rate that MUST be available to ensure proper backwashing and adequate media life. While lower flows can be used and MAY provide adequate results, using less than the recommended flows WILL void the 30-day satisfaction guarantee. Warranties on the tank and control valve will remain unaffected.
*Important Note
Filox is the most widely known brand name for filtration media containing a minimum of 75% manganese dioxide. Other brand names shipped may include (but are not limited to): Catalox, Terminox, and MangOx, all containing a minimum of 75% manganese dioxide.

    Filox 5 System

    Posted by RJ on Jul 24 2020

    I needed to get an iron filter so my sub-irrigation lines wouldn’t clog. Mark B. was excellent in explaining my options and answering all questions so I could make an informed decision. Received my lab reports on iron after install and was shocked when I saw Iron - .012 mg/L and Manganese - 2.6 ug/L. Those numbers could be considered only trace amounts. Noticed the soap lathering in the shower right away. No spots on the dishes and I’m confident I won’t be seeing any orange staining on my high dollar tech. shirts after laundry. Only downside is my system using 140 gals. every 3 days for the 2 cycle backwash. Nothing you can do about it if you want your media to last and do the job. Probably going to route some of the water to cistern for surface watering of lawn and gardens. Only unknown is how the system will perform over the long term. Very easy to plumb in to existing system right after pressure tank. Wish I would have done this 36 years ago when I bought house. Very happy I put my trust and money with AFW filters.

    I am impressed with how well this small unit clears up our iron, manganese and hydrogen sulfide. It gets everything. The water has never been so clear. I don't care for the bulky control head and it likes to trickle drops through the discharge tube after it cleans itself (about 1 drop per second or two, not a lot), but the water quality far outweighs the minor concern. I set it for a two day cycle. It really doesn't use a lot of water for backwashing, which is good because we have a low flow well. Great unit, very happy with it.
