PA-E Reverse osmosis RO-122 Replacement filters, 99.9% Reduction rate of bacteria, pesticides, herbicides, and heavy metals from tap water.
 
The main stage in this system is the RO membrane, and all of the other replacement filters serve and protect that membrane.
 
If the pre-filters fail to work due to poor quality, your RO membrane will not give you a 99% reduction rate. 
 
PA-E RO-122 Reverse osmosis 100% Organic - 50 Gallon per Day thin film TFC NSF Certified.

The 4-stage water filter systems always include three pre-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 RO systems can last around 8 To 12 months between changes.
 
Organic PA-E RO-122 RO membranes can last as long as five years.
 
 
 Stage 1-
The sediment cartridge is the first filter installed in the PA-E Reverse Osmosis RO-122 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 Micron.
Dimensions: 9.75" x 2.5"
Lifetime: Replace every year, depending on the water quality.

For PA-E reverse osmosis RO-122 water filters. This PE-A  RO-122 Filter is wrapped and sealed and meets NSF Standards and Regulations. The filter will fit any Residential Reverse Osmosis Unit with standard 10” filter housing.
 
Stage 2-
Original pa-e ro-122  Activated Carbon Block Filter are made of fine coconut shell carbon 
to remove odors and tastes of many organic compounds, chlorine especially. Though, 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: 9.75" x 2.5"
Dimensions: 9.75" x 2.5"
Lifetime: 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 with standard 10” filter housing.
 
Stage 3-
pa-e ro-122 reverse osmosis under counter sink replacement filters has a - 50 Gallon per Day NSF Certified Thin Film TFC Membrane is the main component of pa-e ro-122 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 pa-e ro-122 reverse osmosis 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, 20 Times smaller than any virus
