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.
The cartridge size for this canister is an industry standard 10" x 2.5" size. We suggest a 20 micron sediment cartridge be used prior to allowing the water to enter the RO or RO/DI unit. This will trap larger sediment in the water and prolong the life of the 5 micron sediment filter that is part of the RO or RO/DI unit. The sediment prefilter can be easily plumbed into your existing or new RO or RO/DI filtration system. See next page for standard plumbing diagrams using a sediment prefilter.
New York City Prefilter
A recommendation from Aquatic Life
Based on information presented in the most recent Water Quality Report, we suggest using an additional prefilter for RO and RO/DI systems that use the NYC area water supply.
The report states that the water company is not required to filter the sediment in the water, they only treat it. Depending on the conditions of the water supply, the sediment levels can be high and clog sediment filters in RO units very quickly. We see this problem mostly in late winter and late spring.
The following is an exerpt from the 2019 New York City Drinking Water Supply & Quality Report:
TREATING OUR DRINKING WATER
Due to the very high quality of our Catskill/Delaware supply, New York City is one of only five large cities in the country with a surface drinking water supply that does not utilize filtration as a form of treatment. The Catskill/Delaware supply operates under a filtration waiver, referred to as the “Filtration Avoidance Determination” (FAD). The water from this supply is treated using two forms of disinfection to reduce microbial risk.
