Buy Online set of 4 filter replacement cartridges for under sink FMRO4-MAN - 4 stage under sink FMRO4-MAN reverse osmosis water systems. WP-5 WP5-50 KP-5 B-RO5N-50 99.9% Reduction rate of bacteria, pesticides, herbicides, and heavy metals from tap water, the main stage in this system is the RO membrane. All of the other replacement filters are serving and protecting that membrane.
 
If the pre-filters fail to work due to poor quality, your RO membrane will not give you a 99% reduction rate.
 
It includes three filters and a membrane 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 FMRO4-MAN RO systems can last around 8 To 12 months between changes.
 
Only the original organic RO membranes can last as long as five years.
 
Stage 1-
The sediment filter is the first filter installed in FMRO4-MAN reverse osmosis water filter system. The primary function of a sediment filter is to remove large and fine particles from 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 microns.
Dimensions: ( DXI 9.2 X 1/4 - 7/8") x 2.6"
Lifetime: please replace every year, depending on the water quality.
 
This filter is wrapped and sealed and meets NSF Standards and Regulations.
The filter will fit any residential reverse osmosis unit that features standard 9.9" filter housing ( look for compatible systems list )
 
stage 2 and 3
 
Remove odors and tastes of many organic compounds and chlorine especially. They're the same e- Organic original Activated Carbon Block Filter made of fine coconut shell carbon. Because this filter is made of packed carbon (forming a cylinder block), they offer a much finer filtration of suspended particles and dirt.
 
Micron rating: 5 Micron.
Dimensions: ( DXI 9.2 X 1/4/7/8") x 2.6"
Lifetime: please replace every year, depending on the water quality.
 
These filters are wrapped and sealed and meet NSF standards and regulations.
The filter will fit any residential reverse osmosis unit with standard 9.9" filter housing ( look for compatible systems list ) WP-5 WP5-50 KP-5 B-RO5N-50.
 
Stage 4-
 
FMRO4-MAN 50 GPD NSF-certified thin film TFC Membrane is the main component of FMRO4-MAN, the ( Hook Shape ) reverse osmosis unit.
 
They are made with 100% Organic fine thin film flat sheet 99.9% Reduction rate of bacteria, pesticides, herbicides, and heavy metals from tap water.
Only the original organic FMRO4-MAN membrane has The micron rating of a thin film less than 1/10000th of a Micron, which is 620,000 times finer than human hair, 2,500 times smaller than bacteria, and 20 Times smaller than any virus.
