What is a DI filter?
DI stands for deionization. The DI filter takes reverse osmosis to a higher level of filtration. It is an
excellent inline filter, especially for those who live in areas with exceptionally high levels of total
dissolved solids (TDS) in their tap water. The DI filter takes the small percentage of contaminants that
the membrane could not remove and filters the water to 99.99% purity, and give you close to 0 ppm
TDS. Conductivity attainable less than 0.1uS/cm or resistivety of close to 18 meg.ohm.
What is a UV filter?
Our UV filter comes with an 11W UV sterilization lamp in a stainless still housing. The UV kills 99%
of viruses and bacteria in the water. The UV light has wavelengths between 250 and 270 nanometers
(UVC or UVC band) and is extremely effective in killing many species of bacteria, mold spores,
viruses and other microorganisms. It is recommended for customers who use well water, rain water, or
have bacteria concerns in their water.
What is a TDS meter?
A TDS meter is a handheld Total Dissolved Solids tester. TDS is the total weight of all solids
dissolved in a given volume of water. It is expressed in parts per million (PPM). With a TDS meter,
you can compare the quality of the RO water with your original source water, and also periodically
check the RO water to know when it’s time to change the filters.
Maximum distance from tank to faucet
We recommend staying under a total distance of 15 feet of tubing between the tank and the RO faucet
or output location. The system will produce a faster flow at the faucet with the shortest tubing run from
tank to faucet.
What is an ASOV and what does it do?
The ASOV is the automatic shutoff valve. This valve allows the system to turn off the water supply
using pressure from the pure water side of the system. The ASOV is a critical piece to the system as it
saves water, extends filter life, and improves the performance of the unit. As the storage tank fills, the
tank pressure increases. When the tank fills completely, a pressure signal is sent to the ASOV, and the
water supply to the system is shut off.
