Buy online with the best price in the USA. Set of 5 Replacement filters made of organic cellulose in a standard size for the 5-Stage Green Reverse Osmosis System Pentair GRO 50EN TLC Encapsulated
 
Pentair high recovery TLC encapsulated membrane under the Ketchn sink, green reverse osmosis systems,  compatible with PA-E RO 132 and Aquasky ROT-4 water systems.
 
With a 99% reduction rate of bacteria, pesticides, herbicides, and heavy metals from tap water, these filters are also suitable for universal reverse osmosis water systems with 10" standers housings.
 
The package contains four Filters and one Membrane, a total of five replacement cartridges that must be periodically replaced.
 
Each filter represents a different stage that the water goes through during purification.
 
Pre-filters and post-filters in the Pentair GRO EN50 Green Reverse Osmosis Systems can typically last 8 to 12 months.
 
Only these original organic RO membranes can last up to 5 years. 
 
Stage 1 
 
The purification process involves a sediment filter that removes large and fine particles from drinking water, such as sand, dirt, silt, and rust. By removing these particles, the filter allows for better performance of all the following filters, such as carbon block or GAC filters.
 
This filter has a micron rating of 5 microns,
Dimensions of (10") x 2.5"
It should be replaced every year, depending on water quality.
The filter is wrapped and sealed and meets NSF Standards and Regulations.
It will fit any residential reverse osmosis unit with a 10" filter housing.
 
Stage 2
 
It involves a reverse osmosis replacement original organic activated carbon GAC filter, known for its highly efficient reduction of chlorine taste and odor and the taste and aromas of many organic chemicals and volatile organic compounds.
 
All GAC filters are made with organic, high-quality coconut shell carbon.
This filter has a micron rating of 5 microns.
Dimensions of (10") x 2.5".
It should be replaced every year, depending on water quality.
The filter is wrapped and sealed and meets NSF Standards and Regulations.
It will fit any standard-size universal residential reverse osmosis unit with a 10" filter housing.
 
Stage 3
 
It involves an organic original activated carbon block filter made of fine coconut shell carbon to remove odors and tastes of many organic compounds and chlorine.
 
These filters are made of packed carbon (forming a cylinder block), which offers a much finer filtration of suspended particles and dirt.
This filter has a micron rating of 5 microns.
Dimensions of (10") x 2.5".
It should be replaced every year, depending on water quality.
The filter is wrapped and sealed and meets NSF standards and regulations.
It will fit any standard-size universal residential reverse osmosis unit with a 10" filter housing.
 
Stage 4 
 
It involves the original organic High Recovery Pentair GRO 50EN Reverse Osmosis Membrane, compatible with all green reverse osmosis systems.
 
50-GPD (gallons per day) NSF-certified thin film TFC making it the primary and most effective component of this reverse osmosis unit.
It is made with a 100% organic fine thin film flat sheet.
This membrane has a 99% reduction rate of bacteria, pesticides, herbicides, and heavy metals from tap water.
This membrane has a micron rating of 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.
Maximum operation pressure of 125 psi (0.86 MPa).
Maximum feed flow rate of 2-GPM.
Maximum operating temperature of 113° F (45° C).
It can tolerate 0 chlorine and has a feed water pH range of 7-8
 
Stage 5
 
It involves an organic inline carbon filter for reverse osmosis (RO) water system, known as a polishing filter. It is usually the last stage of any standard reverse osmosis circuit.
It is made of high-quality coconut shell carbon.
 This filter stabilizes the water-tasting qualities and removes any traces of bad taste and odors.
This filter has dimensions of 10.7 "x 2.3".
It should be replaced every 1-2 years.
The filter is wrapped and sealed and meets NSF Standards and Regulations.
