The Aquatic Life Twist-In 100 GPD 4-Stage Reverse Osmosis Osmosis Deionization (RODI) filtration system is a very compact water purification solutions that efficiently combine reverse osmosis RO technology with their 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. 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.
NOTE: Filter Cartridges and Membrane life may vary based on local water conditions and amount of use.

Q
I want to build a stand to mount this on, as I cannot mount anything in my apartment. What are the dimensions of the unit itself, with all cartridges installed?
I would recommend a inline tds meter as then no guessing on when they need to be replaced but 6 months to a year on most dependent on your individual water needs

A
The sediment and carbon filters should be changed every 6 months. The RO filter should be changed every 2 years. The DI resin should be changed when it completely changes color.
Questionable about a smaller unit truly being 100gpd with real zero TDS read outs. Well, it works. Easy to install and love the cartridge replacement options other than the messy alternative. Reasonably priced and so are the replacements! So far a win!
CONS
Leaky, bad product support and clogs constantly even with minimal use
REVIEW
I have been through two of these things they leak everywhere and clog which I have never seen with any unit also the company namely Dave was rude and condescending throughout two exchanges of this crap product.
CONS
very slow operation, must be watched on storage or water bottle fill.

I bought this to make my own water at home and it has saved me from having to deal with lugging it from the store. It is nice to always have extra water readily available. The only issue is that it is a bit slow but that may be due to the pressure in my home. Set up was easy enough but I did have to improvise a little bit when connecting it to a water line. Overall good product.Hide
