STAGE 3 - Carbon Block Post Filter  - Replace Every 12 Months
STAGE 4 - Carbon Block Post Filter  - Replace Every 12 Months

The Arrowhead Puritap RO system is an obsolete system that filters your water in 3 stages. Sediment, chlorine, taste and odor are reduced by the sediment and carbon filters, and impurities larger than .001 microns are filtered out by the CTA RO membrane.

Arrowhead Puritap RO SET OF 4 REPLACEMENT FILTERS

$164.00Price
  • Arrowhead Puritap 4 stage reverse osmosis replacement filters  original organic cellulose for 4 stage, under sink reverse osmosis water systems,100% reduction rate of bacteria, pesticides, herbicides, and heavy metals from tap water, the main stage in this systems is the RO membrane and all of the other replacement filters are serving and providing protection to that membrane, if the pre-filters fail to work due to poor quality, that means your RO membrane will not give you 100% reduction rate. Arrowhead Puritap include 3 filters and amembrane that must be replaced periodically, The different filters represent the different stages that the water goes through while being purified, Generally - Pre-Filters and post-Filters in aquasky RO systems can last around 8 To 12 months between changes.

    Only the original organic Arrowhead Puritap RO membranes can last as long as 5 years

     Stage 1-

    • Sediment filter is the first filter installed in all under sink 4 stage reverse osmosis systems
    • The main function of a sediment filter is to remove large and fine particles from a drinking water, such as sand, dirt, silt, and rust particles. Removal of such particles allows for a better performance of all the following filters, such as carbon block or GAC filters.
    • Micron rating: 5 micron.
    • Dimensions: ( DXI 8.2 X 1/4 - 7/8") x 2.5"
    • Lifetime: please replace every year, depending on the water quality.

    This filter is wrapped and sealed and meets NSF Standards and Regulations. Filter will fit any residential reverse osmosis unit that features standard 10” filter housing  ( look for compatible systems list )

    stage 2-

    • Organic original Activated Carbon Block
    • Filter are made of fine coconut shell carbon 
    • Remove odors and tastes of many organic compounds and chlorine especially.
    • Because this filters are made of a packed carbon (forming a cylinder block), they offer a much finer filtration of suspended particles and dirt.
    • Micron rating: 5 Micron.
    • Dimensions: ( DXI 8.2 X 1/4 - 7/8")  x 2.5"
    • Lifetime: please replace every year, depending on the water quality.

    This filter is wrapped and sealed and meets NSF standards and regulations. Filter will fit any residential reverse osmosis unit that features standard 10” filter housing ( look for compatible systems list )

    Stage 3-

    • Original organic 50 GPD NSF certified thin film TFC RO membrane
    • Membrane is the main component of  your 4 stage reverse osmosis unit.
    • Made with 100% Organic fine thin film flat sheet
    • 99% reduction rate of bacteria, pesticides, herbicides, and heavy metals from tap water.
    •  Only the original organic aquasky rot -4 membrane has The micron rating of a thin film less than 1/10000th of a Micron which is 620,000 times finer than A human hair,  2,500 times smaller than bacteria and 20 Times smaller than any virus.

    Stage 4 -

    • Original organic carbon filter for under sink 4 stage reverse osmosis is known as polishing filters, because they would usually be the last stage of any standard reverse osmosis circuit.
    • Being made of high quality coconut shell carbon they stabilize the water tasting qualities and further remove any traces of bad tastes and odors.
    • Dimensions: 10.7 " x 2.3"
    • Lifetime: please replace ones in 1- 2 years.
