The Aquatic Life Twist-In 100 GPD 4-stage reverse osmosis filtration system is a very compact water purification solution that efficiently combines reverse osmosis and deionization (RODI) technology with our quick and easy to change twist-in replacement filter cartridges. The new Twist-In media cartridge design makes filter changes simple, easy and clean no tools required and no mess! The Twist-In cartridges can be easily changed in only seconds with just a quarter turn and without contact with used filter material, and the supply water to the unit does not have to be turned off to replace any cartridge. Stage 1 Sediment filter: recommend replacing every 6 months.
The first stage of your RODI unit is a 5-micron sediment filter that traps sediment and other particulate matter like dirt, silt and rust which will affect the taste and appearance of your water. Stage 2 Carbon Block filter: recommend replacing every 6 months. The second stage of your RODI unit is a carbon block filter. The Activated carbon in the filter reduces chlorine by 99% and conditions the water prior to the RO membrane. Stage 3 RO membrane: recommended replacing every 1-2 years.
The RO membrane reduces impurities known as total dissolved solids (TDS) from the water down to 1/10,000 of a micron, reducing arsenic, lead, parasitic cysts, COPPER and more. Stage 4 Color Changing DI Resin (deionization): replace filter when resin changes color to amber. After the water is filtered by the membrane, there is usually a small amount of total dissolved solids (TDS) left in the water. In certain non-drinking water applications, it is important to remove the remaining TDS from the water. This is accomplished by filtering the water through a resin that is charged with cation and anion resins (H+ and oh-).
As the resin absorbs the TDS, it will change color. When all resin has changed color, it is time to replace the DI cartridge. Assembled product dimensions: 12L x 4D x 13H.
