Reverse Osmosis systems need to have filter replaced to ensure quality of production. We recommend you to replace your filters in a timely fashion, to ensure your system works at peak performance.
4 Stage RO Systems Filter & Recommended Replacements Time
Stage 1 - Sediment filter, recommended change of 6 months (MAX)
The first stage of your RO system is a five micron sediment filter that traps sediment and other particulate matter like dirt, silt and rust which affect the taste and appearance of your water
Stage 2 - Carbon Block Filters, recommended change 6 months (MAX)
The second stage contains a 5 micron carbon block filter. This helps ensure that chlorine, chloramines and other materials that cause bad taste and odor are greatly reduced.
Stage 3 - Membrane, recommended to be changed approximately every 2 years.
Stage three is the heart of the reverse osmosis system, the RO membrane. This semi-permeable membrane will effectively take out TDS & Sodium and a wide range of contaminants such as Percholate, Chromium, Arsenic, Copper, Lead as well as Cysts, such as Giardia and Cryptosporidium. Because the process of extracting this high quality drinking water takes time, your RO water treatment system is equipped with a storage tank.
Stage 4 - Carbon inline filter, recommended to be changed every 6-12 months.
The final stage is an inline granular activated carbon (GAC) filter (aka: AICRO) which is used after the water storage tank, and is used as a final polishing filter
