Why does the filtered water taste funny?
1) The filter is about to expire. Check the indicator reminder to confirm and replace it.
2) The system hasn't been used for a while. Turn on the RO faucet and allow it to flush for a while before drinking.
What will happen if I do not change my filter when the filter life indicator light turns red?
Over-used filters will degrade the filtration performance, causing contaminants to leak back into the water and adversely affect your health. It's recommended that you replace the filter if the filter life indicator light turns red.
Why is the filter life indicator light still red after I changed the filter?
You have not reset the filter life indicator. Please reset it: Press and hold the CB filter life indicator for 7 seconds, until the system beeps and the blue light stays on.

We love the system.

Value for the money has low marks because I still feel that the company has overpriced their filters. Bjt that's with most filters I suppose. But they work. They are reliable, easy to install. Doesnt leak and we've been very happy with the system.

easiest to use ro filter system ever

it's expensive. buy it anyhow. because once installed, all you do is wait for the warning lights to change color, change out that filter in a matter of seconds without disconnecting or moving a thing, and your good for another 6 months to 2 years depending on which filter was exhausted. I have had about 5 systems before this, nothing comes close to this in terms of efficiency and ease of use. our previous one would give us a flow of filtered water for about 10 seconds, then dribs and drabs. this one, open the faucet, fill your vessel, shut it off. volume is the same throughout. great product and highly recommended.

Great system

Well designed system with easily replaceable cartridges, small footprint and great tasting water. Update: water quality is amazing - no aftertastes. For the first time in years ( and several RO systems) my family is enjoying clean non bottled water. The genius of this unit, in my opinion, is the filter replacement timer/computer. Many people forget to replace their RO filters (see those 7 filter units) and are drinking questionable water. This unit solved this problem.
