Review on Enhanced Filtration Monitoring with iSpring RO500 Tankless System by Jon Estell

This is an excellent reverse osmosis system. Recently moved and had to install RO. I searched for a long time and decided on this model. Previously iSpring used reverse osmosis systems. It's awesome. The faucet tells you in real time how many ppm of water it is dispensing. The device beeps when the filter cartridge needs to be replaced. iSpring customer support is fantastic. Definitely recommend. UPDATE: There was a problem with the device after replacing the CB filter. The problem was my fault, the device was fine. The support team was very responsive. I spoke to Don a few times and he went out of his way to ensure the unit was working properly.
