• Highest flow rate of any iron removal media - Because of its superior performance potential, Filox supports a significantly higher service flow rate per bed size and can be used in smaller filters than Birm and Greensand. An 9" diameter Filox filter actually exceeds the service flow capacity of a 12" diameter Birm or Greensand filter. 
• No oxidizing chemicals needed for regeneration
• High efficiency with 80% manganese dioxide for enhanced performance and capacity - Filox (often called Pyrolox) is superior to most other oxidizing medias because of its very high manganese dioxide content. Manganese dioxide is the active ingredient of all leading iron/manganese reduction systems. Filox consists of 80% manganese dioxide.  Manganese Greensand is 3% and Birm is 1% manganese dioxide. The high manganese dioxide content produces a much more active and kinetic media, and is therefore, a much more effective product.
• Effective from 5.0 to 9.0 pH - Filox operates within a much broader pH range than most iron-reduction media. It can be used to treat waters that are significantly lower in pH than Birm. Unlike Birm, Filox is chlorine tolerant. In fact, it works well with all the standard oxidizing agents (chlorine, potassium permanganate, hydrogen peroxide, ozone, air).
• System is easy to program -  10 pre-programmed regeneration cycles to optimize water treatment
• Filox has an expected lifespan that is 7500 times that of Birm  (Greensand can be expected to last 50 times as long as Birm.) Filox also has superior particle strength which makes it hold up better than other media during the frequent backwashing required of iron filters.
• Higher Capacity for Iron, Manganese and Sulfur - Filox alone, without additional oxidizers, under the right conditions, a cucic foot is capable of handling up to 15 ppm (parts per million) iron, 7 ppm hydrogen sulfide, and 3 ppm manganese. Capacity increases greatly with the use of oxidizers as pretreatment.
• CK10 Valve Backwashes Filox effectively - Easy to program, solid-state, 5-year warranty
• Advanced Vortech Tank requires less backwash water and effectively regenerates Filox - much better than a standard distributor - 10-year tank warranty
• Includes Everything - Media, Connectors and Bypass Valve

You can buy a Filox filter from some other company, but if it doesn't have the VORTECH tank, it's not even close to US Water's Filox Filter. 

Are There Any Drawbacks to Filox?

• Filox is very heavy. It weighs so much that it can only be packed in half cubic foot (57 lbs.) bags.
• For UPS shipping, Filox requires special boxing. Birm weighs less than half as much. Filter carbon, by contrast, weighs about 1/4 as much as Filox.
• Compared with Birm and Greensand, Filox is very expensive.
• Filox requires more frequent backwashing under higher flow rates than most iron removal media, except in very light-duty situations - daily backwashing is preferred. Therefore, it uses more water and requires more wastewater disposal.
