Our Whole House water filtration systems are designed to deliver safer, cleaner, water to every faucet and shower head into the whole house without reducing water pressure. By using oversized filter cartridges and housings this system maintains the strongest water pressure possible. In addition, these larger housings and filters require less frequent services, which saves you time, money, and effort.

Pre-loaded Filter Cartridges:

  • 1st Stage: 5 Micron Polypropylene Sediment Filter 104112
  • 2nd Stage: Refillable Iron Manganese Filter 104121
  • 3rd Stage: (CTO) Carbon Block Filter 104114

Vertical Hydraulic Gauge

Having a pressure gauge is helpful in monitoring your incoming water pressure, internal unit pressure & when to replace the filters. It's best to replace the filters when you see changes in the reading start, an increasing pressure drop is a good indication that the cartridges are starting to clog with particulate or the filter's media is exhausted as the water inside the system can't pass through the filters normally.

About Our Iron/Manganese Filter

Manganese Sand is an efficient and economical media for the reduction of dissolved iron and manganese compounds from raw water supplies. It may be used in either gravity-fed or pressurized water treatment systems like our whole system. Manganese Dioxide acts as an insoluble catalyst to enhance the reaction between dissolved oxygen (D.O.) and iron compounds. In ground waters, the dissolved iron is usually in the ferrous bicarbonate state due to the excess of free carbon dioxide, this is generally not filterable.

Manganese Dioxide acts as a catalyst between the oxygen and the soluble iron compounds, enhances the oxidation reaction of Fe++ to Fe+++, and produces ferric hydroxide which precipitates and may be easily filtered. The physical characteristics of Manganese Dioxide provide an excellent filter media that is easily cleaned by backwashing to remove the precipitant. Manganese Zeolite is not consumed in the iron removal operation and therefore offers a tremendous economic advantage over many other iron removal methods.

Other advantages of Manganese Dioxide include; a long material life with relatively low attrition loss, a wide temperature performance range, and extremely high removal efficiency. Negligible labor costs are involved because Manganese Dioxide does not require chemicals for regeneration, only periodic back washing is required.

This system reduces the possibility of damage to pipes and water heaters and reduces up to 3 ppm of dissolved iron. It also helps to eliminate the orange and brown stains often found in toilets, sinks, etc.

Recycling of peregenerant and rinse water will conserve KMNO4 and rinse wastewater. This system is designed to provide an easy and effective method of reducing iron from water and greatly improves the taste of your water as well.


  • Sediment Filter Life: Approx. 6 - 12 months
  • The approximate Iron filter for 4 users is 320 days, or 80,000 gallons of use (which is first) if your iron level is 1 PPM, if your iron level is 2 PPM then the filter life will be 40,000 gallons.
  • Carbon Filter Life: Approx. 20,000 Gallons
  • Maximum Operating Pressure: 90 PSI
  • Operating Temperature Range: 40-100°F (5-40°C)
  • Dimensions: 27.5 height x 24.5" width x 8" depth
  • Weight: Approx 50 lbs.
  • Feed Water pH range: 4.0-10.0
  • Preferable feed water pressure range: 50-70PSI to get the best filtration results keep it at 60 PSI.
  • Maximum Feed Water TDS: 1000 ppm, Iron less than 4 PPM
  • Pressure Drop @10GPM: Less than 1 PSI
  • Estimated Flow Rate:
    • 1-20* GPM for 1" Inlet/Outlet
    • 1-15* GPM for ¾" Inlet/Outlet

Total Dissolved Solids.
* Pressure drop will be determined based on feed water pressure, filter cartridge, fluid viscosity, filter life, and conditions.


  • Electroplating, etching & image development process in the PCB industry
  • Filtration of electroplating fluid in the conventional electroplating industry
  • Pre-filter of DI & RO water filtration system for industry
  • Filtration of low-viscosity fluids of chemical
  • Filtration of water for manufacturing processes & recycled water

Approximate Life of Iron/Manganese Filter Cartridge:

Filter life depends on the contamination level (iron equivalent) and the amount of water consumed daily. You can use the following chart to estimate how long a filter will last in your case.

"Iron Equivalent" is calculated as follows: (Iron level) + (2 x Manganese level) + (3 x Hydrogen sulfide level)

If you are not sure about your Hydrogen sulfide level (it is hard to accurately test for) and you have a noticeable rotten egg odor, assume a Hydrogen sulfide level of 0.5 ppm. If the rotten egg odor is severe, assume a level of 1.0 ppm.

Example: Test results are 0.8 ppm iron, 0.2 ppm manganese, and you have a rotten egg smell in your water.

Iron Equivalent = (0.8) + ( 2 x 0.2) + (3 x 0.5) = 2.7

Estimated Life of WH5 Iron Filter Cartridge:

Specifications & Operating Conditions:

NOTE: Some water supplies contain tannins with iron, if you have only tannins without iron in your water supply, please let us know so we can include a different media filter type.

Tannins are astringent, bitter-tasting plant polyphenols that bind and precipitate proteins. The term tannin usually refers to the source of tannins used in tanning animal hides into leather. However, in this case, we are referring to the brown discoloration in the water, often caused by decaying organic matter. Tannins in well waters form from humic acid, a complex mixture of many different acids containing carboxyl and phenolate groups produced by the biodegradation of dead organic matter. Tannins can also be found in peat, coal, many upland streams, and ocean water.

Tannins can be removed by self-cleaning automatic tannin filters. These filters remove tannins by using anion ion exchange media. These units regenerate using rock salt (sodium chloride) in much the same way water softeners function. Frequently, we'll see shallow-dug wells (less than 50ft deep) that fill with run-off water, and develop high levels of tannins during heavy rainy periods. Ideally sealing off the well from surface run-off would solve the problem, but a tannin filter is often an excellent, relatively low-cost alternative.

Occasionally these tannins are accompanied by iron (Fe) or manganese (Mn). Water high in iron or manganese can sometimes be reddish, rust-colored, brown, tan, black, or even greenish in color. Chlorination or ionization water treatment, followed by an iron filter like our Manganese Sand Whole House Filter can be very effective at removing both tannins and these oxidized iron particles.

No More Hydrogen Sufide!
I bought this to clean up the iron and hydrogen sufide in my water. I coupled it with an RO system. I started out with 1200 TDS and Post filter it was 800-1000 with not a hint of smell and crystal clear. Post RO and remineralized my TDS is now 150. Equipment looks to be excelent quality and I intalled myself with no problems. Hugh savings over the quote I received from an unamed company, more than 4 times. Needless to say we are very happy.

This system is fantastic. It arrived quickly and on time. It was complete with all of the parts. Installation was very quick and easy. It works fantastic! The water pressure in and out of the system is the same with no noticeable drop. You can see an immediate difference in the water. High quality, good support, excellent company. Would highly recommend them!

Bought this for my well water, which I did have tested before hand. Water is definitely better, coffee is smoother, BUT DID NOT REMOVE SULFUR SMELL AS ADVERTISED.
