5 STAGE PA-E under sink reverse osmosis water systems include 3 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 the PA-E RO 132 water systems can last aroumd 8 To 12 months between changes. RO membranes can last as long as 2 to 3  years .

        Stage 1 - Pre-Membrane reverse osmosis sediment filters

• Replacment High-Grade 5 micron high-capacity  sediment filter 

• Remove larger particles & suspended matter such as dirt, silt, rust, sand from water.   

• Protects and extends the life of the membrane and system.

• Recommend replace every 8 -12 months, varies depend on the water source quality   

• Standard Size  water filters 24-3/4" / 10" 5.5 /15-( 97%)

• Stage (1) Pre-Membrane

            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.

• Dimensions: ( 9 3/4 ) x 2.5"

• Lifetime: 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

          Stage 3- CTO Coconut Shell Carbon Block Filter

• Organic CTO Coconut Shell Carbon Block Filter

• Forceful remove pesticide residues in water, water pollution odor of ozone, chlorine removal of residual heavy metals, bacteria, sterilization rate if 99%.

• Standard Size 9 3/4" / 10" 5.5 /15-( 97%)pxi - CVM

• Recommend replace every 8 To 12 months.

• Protects and extends the life of the membrane and system.
