Compare Iron Filters
Selection of an iron treatment system is based on a number of factors, including:
Certain iron treatment systems are able to remove not only iron, but also manganese and hydrogen sulfide which can be often found in the same waters. Hydrogen sulfide is responsible for an unpleasant rotten egg or sulfur odor. If you have manganese and hydrogen sulfide in your water in addition to iron, you should select a treatment method that can remove these contaminants at the same time.
Level of Contaminants Present
Our smaller WH5 and WH6 systems contain less treatment media than our larger backwashable systems - accordingly, they are unable to treat high contamination levels. Furthermore, certain types of treatment media are more powerful catalysts or oxidizers and can treat higher contaminant levels. This is particularly true of Filox-R.
Many treatment media are sensitive to the pH conditions of your water, particularly if it is acidic. Select a treatment option that is suitable for your pH conditions, or use an acid neutralizer filter to raise the pH level ahead of your iron filter.
Flow Rates and Backwash Capacity
Be aware that due to the volume and type of media present in each treatment system, the flow rate capabilities of all systems are not equal. Select a model that will meet your flow rate needs. The cartridge-based systems are capable of acceptable flow rates for most small homes, but for higher flow applications, a backwashable system will be necessary. If a backwashable system is selected, it is critical to ensure that sufficient flow rates will be available for backwash.
Long Term Operating Cost
While cartridge based systems are very economical at the start, they do require the periodic replacement of their filter cartridges to maintain performance. Backwashable systems cost more initially but the media can last a very log time, sometimes indefinitely, resulting in a lower overall cost in the long-run. For low flow applications where contaminant levels are generally low, especially cabins and recreational properties, cartridge based systems can have a long-life and are often preferred.

Please consult us for recommendations where contaminant levels exceed the above thresholds or if your situation does not meet the above criteria. Custom units are available.
* Use of this system for manganese reduction is acceptable but only if pH is 8.0 to 8.5 and iron to manganese ratio is 10:1 or higher
** pH correction is recommended where pH levels are less than 6.5 to prevent damage to your plumbing system and potential leaching of metals from solder as well as copper and brass plumbing components.
*** Service flow rates expectations should be reduced where contaminant levels are approaching the maximum stated levels above, particularly if multiple contaminants are near these levels.
