Set Of 4 (RO) Replacement filters PA-E RO-122 Reverse Osmosis These filters boast a 99% Reduction rate of bacteria, pesticides, herbicides, and heavy metals in tap water. The main stage of the PA-E RO-122 system is the RO membrane, and all other replacement filters protect and maintain the RO membrane's effectiveness. If the pre-filters fail due to poor quality, the RO membrane will not provide a 99% reduction rate.
 
You can purchase PA-E RO-122 replacement filter cartridges online, including all four stages of filters for under-counter sink parts.
 
The system includes three pre-filters and a membrane that must be periodically replaced. The different filters represent the various 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.
Only the original PA-E RO-122 RO membranes can last 5 years.
 
The sediment cartridge is the first filter installed in the PA-E RO-122 Reverse Osmosis water filter system. Its primary function is removing large and fine particles from drinking water, such as sand, dirt, silt, and rust. Removing such particles allows for better performance of all the following filters, such as carbon block or GAC filters. The micron rating for this filter is 5 Microns, and its dimensions are 9.75" x 2.5". It needs to be replaced every year, depending on the water quality.
 
The second stage of the PA-E RO-122 filter system includes original PA-E RO-122 activated carbon block filters made of fine coconut shell carbon, which removes odors and tastes of many organic compounds, especially chlorine. The filter is made of packed carbon, forming a cylinder block, and offers a much finer filtration of suspended particles and dirt. The micron rating for this filter is 5 Microns, and its dimensions are 9.75" x 2.5". It needs to be replaced every year, depending on the water quality.
 
The third stage of the PA-E RO-122 filter system includes a 50 Gallon per day NSF certified thin film TFC membrane, the main component of the PA-E RO-122 Reverse Osmosis unit. Made with a 99% organic fine thin film flat sheet, this filter boasts a 99% reduction rate of bacteria, pesticides, herbicides, and heavy metals from tap water. Only the original PA-E RO-122 reverse osmosis membrane has a thin film micron rating of less than 1/10000th of a micron, 620,000 times thinner than a human hair, 2,500 times smaller than bacteria, and 20 times smaller than any virus. The filter is rated for 50 gallons per day (15.8 liters per hour) capacity and 99% stabilized salt rejection. It meets NSF/ANSI standard 58 and is designed for residential reverse osmosis units. It needs to be replaced periodically, depending on the water quality.
 
The fourth and final stage of the PA-E RO-122 filter includes an inline carbon filter, also known as a polishing filter. Made of high-quality coconut shell carbon, this filter stabilizes water-tasting qualities and removes any traces of nasty tastes and odors. Its dimensions are 10" x 2", which must be replaced every 1-2 years.
 
All PA-E RO-122 filters are wrapped and sealed and meet NSF Standards and Regulations. Filter replacements fit residential reverse osmosis units - PA-E RO-122 Reverse Osmosis Water Filters.
