Product Details

Reverse osmosis is the process of removing contaminants from tap water using a special semi-permeable membrane.By applying water pressure across the membrane,contaminants are concentrated on one side of the membrane and filtered water on the
other side of the membrane. This is why reverse osmosis units have a waste water line as well as a filtered line.
In addition to the membrane, water is filtered prior to the membrane with a sediment cartridge to remove larger particulates, and a carbon block to remove chlorine and other materials. After water is filtered by the membrane, it passes through a color-changing resin cartridge where additional total dissolved
solids (TDS) are removed from the water. The cartridges and membrane on your unit are designed for easy installation and replacement. Each cartridge connects to the filter housing by simply inserting and twisting. It is important the cartridges be installed in the correct order to effectively
filter the water.


The new Twist-In media cartridge design makes filter changes simple, easy and clean – no tools required and no mess! 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.

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.

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

STAGE 4 – TWIST-IN MIXED BED COLOR CHANGING RESIN DEIONIZATION CARTRIDGE: Replace filter when resin changes color completely to amber. When all resin has changed color, it is time to replace the DI filter.

  • Small footprint of the unit makes it easy to place under cabinets or in limited spaces.
  • Twist-In cartridges for fast and easy replacement of filter media.
  • Triple-sealed cartridges ensure trouble-free operation.
  • Compact design with pivoting cartridge heads is perfect for small spaces.
  • Mounting Brackets hold the unit securely while mounted in a convenient location.
  • Includes everything for installation: Tubing, Water Supply Connectors, Drain Connector.

NOTE: The life span of the filter cartridges, including the membrane, are dependent on multiple factors.
These include the quality of the incoming water supply (TDS levels, chlorine, etc.) as well as the
amount of use. Recommended replacement intervals are based on average usage
