(3) 20"x 4.5" water filter cartridges that are designed for high-flow water filtration applications. Unique, wide cartridges are capable of filtering enough water for a house, apartment or office. Great for well water.

  • First Filter  is a 5 MICRON SEDIMENT FILTER 20"X4.5"

        Sediment cartridge filters are primarily used to remove silt, sand or other particulate matter from water. 

  • Second Filter Cartridge is a multi-stage filter that consists of KDF85/GAC


  • KDF 85 Medium Removes or reduces iron and hydrogen sulfide from water supplies. Also controls scale, bacteria and algae.

    The TWPROBB KD85 Iron/Hydrogen Sulfide reduction filter contains a combination of KDF85 media and coconut shell activated carbon (GAC). KDF85 effectively reduces dissolved iron and hydrogen sulfide odor. Protecting your plumbing system including toilets,bath tubs,showers and appliances such as clothes washers and dishwashers from unsightly staining and odor.

    The GAC activated carbon removes organic contaminants to substantially improve water clarity,taste and odor. It does not add any harmful chemicals to water, making it safe for drinking water applications.
  • Third Filter Cartridge is a Carbon Block filter                                                               
    • Carbon Block Filter 20"x4.5"

  • Carbon Block strains out sediment, dirt, bacteria, microscopic worms, algae, asbestos and cryptosporidium. With water pressure, this compacted solid carbon block is designed to filter sub micron size particles. This micro straining of the water will provide clean and clear drinking water.

  • Fits 20"x4.5" Big Blue Filter Housings. 


**Hydrogen sulfide concentrations exceeding 7 to 10 ppm can be removed by injecting an oxidizing chemical such as household bleach followed up by filtration. The oxidizing chemical should enter the water upstream from the storage or mixing tank to provide at least 30-45 minutes of contact time between the chemical and water. The length of length of the holding time is a function of the chemical dosage, tank configuration and water temperature. Sulfur particles can then be removed using a sediment filter and the excess chlorine can be removed by activated carbon filtration. 

If test results indicate that bacterial contamination is occurring, shock chlorination or disinfection is the most widely suggested method for initial treatment. Shock chlorination (disinfection) is the one-time introduction of a strong solution into the entire water distribution system (well, pump, distribution pipeline, etc.)

When to Shock Disinfect the Well:

Shock chlorination (disinfection) is recommended when lab results indicate a presence of bacteria upon completion of a new well or after pump replacement or repair, when the distribution system is opened for repairs or maintenance, following contamination by flood water, to control iron and sulfur bacteria.

Shock chlorination (disinfection) is recommended in these circumstances to ensure that bacterial contamination is controlled.


This system should be used where low to moderate ferrous (dissolved) iron or hydrogen sulfide contamination is known. This filter is most effective where iron and hydrogen sulfide levels are less than 5 ppm. Best removal rates are achieved where pH is between 6.5 and 8.5 and where water contains some dissolved oxygen.
