The Aquatic Life Twist-In 100 GPD 3-Stage Reverse Osmosis (RO) and 4-Stage Reverse Osmosis Deionization (RODI) filtration systems are very compact water purification solutions that efficiently combine reverse osmosis RO and DI 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. Items: 100 GPD 3-Stage RO System (540370), 100 GPD 4-Stage RODI System (540371).
STAGE 1 – TWIST-IN SEDIMENT FILTER CARTRIDGE: Recommend replacing every 6 months. The first stage of your RO 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. Item 330377.
STAGE 2 – TWIST-IN CARBON BLOCK FILTER CARTRIDGE: Recommend replacing every 6 months. The second stage of your RO unit is a Carbon Block Filter. The Activated Carbon in the filter reduces chlorine by up to 99% and conditions the water prior to the RO Membrane. Item 330379.
STAGE 3 – TWIST-IN RO MEMBRANE FILTER CARTRIDGE: 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. Item 330375.
STAGE 4 – TWIST-IN MIXED BED COLOR CHANGING RESIN DEIONIZATION CARTRIDGE: Replace filter when resin changes color completely 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 filter. Because the process of filtering the high quality water takes time, it is common to use a storage tank to collect filtered water, making it available on demand. Item 330380.

Great product, delivers very good quality water, easy to install.Jan 30, 2017
Delivers very high quality water. TDI input is 318 ppm, TDI out is 4 ppm, without the DI module attached. With the DI cartridge, reading is 0! Took about 1 1/2 hour to install, plus time to purge system & hook up auto shut off at the reservoir barrel. (Shut-off accessory recommended). Produced about 50 gpd @ 45 psi pressure from my well. You should get more water @ higher psi.
Pros: Easy to install, compact, affordable, & easy to change cartridges.
Con: DI cartridge is not refillable, so you will need replacement cartridges when it's spent.
