AQUATIC LIFE Twist-In (TI) 75 GPD, 4-Stage RO/DI Unit

The Aquatic Life Twist-In 75 GPD 4-Stage Reverse Osmosis Osmosis Deionisation (RODI) filtration system is a very compact water purification solutions that efficiently combine reverse osmosis RO technology with its 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 just seconds with a quarter-turn, 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 – 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, such as dirt, silt, and rust, which can affect the taste and appearance of your water.

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.

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 to 1/10,000 of a micron, removing arsenic, lead, parasitic cysts, copper, and more.

STAGE 4 – TWIST-IN MIXED BED COLOR CHANGING RESIN DEIONIZATION CARTRIDGE: Replace filter when resin changes colour completely to amber. After the water is filtered by the membrane, a small amount of Total Dissolved Solids (TDS) remains. 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 colour. When all the resin has changed colour, it is time to replace the DI filter. Because filtering high-quality water takes time, it is common to use a storage tank to collect filtered water, making it available on demand.

NOTE: Filter Cartridges and Membrane life may vary based on local water conditions and usage.
