What are The Best Water Filter Cartridges of Reverse Osmosis Systems?
 

Reverse osmosis water filter system is a popular choice of home water filtration. It effectively filters out chlorine, taste, odor and harmful heavy metal ions completely. While a reverse osmosis system consists various water filter cartridges to keep a good filtration performance. It is an essential part to get familiar with reverse osmosis water filter cartridges inside of a reverse osmosis system.

Here the following parts will show you 3 mostly-see water filter cartridge replacements in a reverses osmosis system.

First Water Filter Cartridge - PP Spun Sediment Filter

In a RO (reverse osmosis ) water purifier system, PP sediment filter is the cartridge which meets and contacts unfiltered water firstly. It blocks most large visible impurities like sand, rust and debris. A PP spun sediment filter captures and intercepts sediment and contaminants larger than 5 micron. After first filtration of PP water filter cartridge, water clearness are increased a lot and left other smaller impurities to the following reverse osmosis water filter cartridges. To keep an optimal performance of your entire reverse osmosis system, the PP water filter cartridge needs to be replaced regularly every 3 to 6 months based on the local water quality and contaminant level.

Second Water Filter Cartridge - GAC Carbon Water Filter

Tap water contains free Chlorine more or less because water supply factory uses Chlorine to disinfects the water. Moreover, when water passes through plumbing systems and water pipes, organisms inside of pipelines will bring some bad taste and odors into water. That’s why manufacturer uses the GAC carbon water filter cartridges as the second filters of reverse osmosis systems. Carbon can adsorb residual chlorine, chemicals and organisms in water efficiently. That helps the homeowners get rid of bad odors like rotten eggs, chlorine and metallic.

Third Water Filter Cartridge - CTO Carbon Block Filter

A CTO carbon block filter cartridge mainly used to filter out chlorine, bad odors, organic compounds still exist in water already filtered by PP sediment filter and GAC carbon filter. What’s more, CTO filter also does a great work on intercept impurities that GAC filter didn’t filter out completely. That is because GAC filter uses granular carbon and some tiny contaminants and pollutants still flow through gaps of carbon granules. CTO carbon block filter also prolongs the lifespan of reverse osmosis membrane (the fourth filter cartridge of reverse osmosis system).

Conclusion of the above 3 water filter cartridges

PP sediment filter, CTO and GAC carbon filters are three mostly-used water filter cartridge replacements in a reverse osmosis water purifier systems. They reduce more than 90% contaminants in unfiltered tap water. The average replacement periods of them are 3 to 6 months depends on water quality and level of contaminants.
