Buy online Romate 4 Reverse Osmosis System Replacement Filters Cartridges - Set Of 4 Stage, organic cellulose for 5 stage under sink Romate 4 Reverse Osmosis Water System , 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. It include 3 filters and a membrane that must be replaced periodically. The different filters represent the various stages that the water goes through while being purified, Generally - Pre-Filters and post-Filters in Romate 4 Reverse Osmosis System Replacement Filters Cartridges - Set Of 4 Stages can last around 8 To 12 months between changes.

Only the organic RO membranes can last as long as five years
Stage 1-
The sediment filter is the first filter installed in Romate 4 Reverse Osmosis System 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 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. The 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 to remove odours and tastes of many organic compounds and chlorine especially.
Because these 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. The filter will fit any residential reverse osmosis unit that features standard 10” filter housing ( look for compatible systems list )

Stage 3-
 50 GPD NSF-certified thin film TFC Membrane is the main component of the Romate 4 Reverse Osmosis Water System 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 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.
