Review on Aquasana Brushed 3 Stage Filter System: Superior Water Filtration for a Cleaner, Safer Home by Stuart Rasmussen

It took me just over an hour to get this device up and running. To my surprise, no leak as other viewers have written. I can tell the difference in water quality right at the faucet compared to this unit as I don't have the means to measure the water quality so I assume the water is filtered through the system unit. I would give it 5* but was held back by the Bluetooth feature. It does not matter. I spoke fast. After the block was installed and working for several days. One of the filters started leaking. So I downgraded it to 2 stars.
