Buy online - Amtrol reverse osmosis replacement filters, Organic cellulose for under sink 5 Stage  Amtrol reverse osmosis water systems RO-4 model , 96-99% reduction rate of bacteria, pesticides, herbicides, and heavy metals from tap water. It includes total of 5 filters 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 this Amtrol reverse osmosis watersystems can last around 8 To 12 months between changes.Only the organic RO membranes can last as long as 5 years

Stage 1-
Sediment filter is the first filter installed in Amtrol reverse osmosis water filters systeme . 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.
 
 
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 activated carbon GAC filter are well-known for their highly efficient reduction of chlorine taste and odor , Taste and odors of many organic chemicals and volatile organic compounds.
All GAC filters are made with organic high quality coconut shell carbon.
 
 
 
Micron rating: 5 Micron.
 
 
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 amtrol reverse smosis unit that features standard 10” filter housing ( look for compatible systems list )

stage 3-
Organic original Activated Carbon Block Filter are made of fine coconut shell carbonRemove 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.
 
 
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 amtrol residential reverse osmosis unit that features standard 10” filter housing ( look for compatible systems list )

Stage 4-
Organic 50-75 GPD NSF certified thin film TFC reverse osmosis membrane is the main component of Amtrol reverse osmosis unit.
Made with 100% Organic fine thin film flat sheet 96-99% Reduction rate of bacteria, pesticides, herbicides, and heavy metals from tap water.
Only the original organic 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.
