The WH5B iron / hydrogen sulfide reduction filter package contains manganese dioxide media
which reduces iron, manganese, and hydrogen sulfide through an oxidation / filtration process,
thereby substantially improving water clarity, taste, and odor, while at the same time protecting
your plumbing system including toilets, bath tubs and showers, and appliances such as clothes
washers and dishwashers, from unsightly staining. It does NOT add any harmful chemicals to the
water, making it completely safe for drinking water applications. A high-capacity 5 micron
sediment pre-filter extends the life of the primary iron filter by trapping sediments, debris, and
oxidized ferric iron particles to prevent pre-mature clogging.
This system should be employed where low to moderate ferrous (dissolved) iron, manganese, or
hydrogen sulfide contamination is known or expected. This filter will also remove ferric iron
through mechanical filtration. This filter is most effective where iron contamination level is less
than 3 ppm (and no greater than 5 ppm) or the hydrogen sulfide level is less than about 2 ppm. If
a combination of iron, manganese, and hydrogen sulfide are present, you must consider the "iron
equivalent" level when determining if this filter will work effectively in your circumstance (see
below). Best contaminant removal rates are achieved where the pH is 7.0 or higher, although
satisfactory contaminant removal can generally be achieved at slightly lower pH levels (6.8 to 6.9)
under most conditions. This filter is not recommended where pH levels are less than 6.8. For best
results, pre-sediment and post-carbon treatment is recommended. A pH level of 8.0 is desirable
for optimal manganese reduction.
The life of the filter depends on the contamination level ("iron equivalent") and amount of water
consumed on a daily basis. You can get a good idea of how long a filter will last in your case by
using the chart below.
"Iron Equivalent" is calculated as follows:
