I know someone that just installed one of these-but not for brewing. I am struck by the name brand, capacity of 14.5 gallons per day,
easy availability of filters, low waste and the fact that it's top rated by consumer reports.
It also has a membrane flush.
I'm tired of making a trip to get pure water
Is there a down side to this that I am not seeing?
Price varies by your zipcode. $147 for me.

How long do the filters last?
We recommend that you change the filters every six months. Leaving the filters in place longer than six months can increase the possibility of bacteria growth on the filters, which could then enter your water supply. The Whirlpool® RO system comes with an indicator light on the faucet to inform you when it is time to change filters.
The RO system also includes a membrane, which is the center of the three filter elements. The membrane will typically last 1-3 years, depending on water usage and the quality of your incoming water supply. The membrane should be replaced when you notice a difference in the taste of your water. The life expectancy of an RO membrane will be longer if you have a water softener because the membrane will not plug up with hard water particles."
