I bought this system in Nov 2019. I used to have another brand of RO System which required so much maintenance efforts. I'd have trouble taking off and replacing the filters and would splash water all over my kitchen. I used to need to spent at least one hour and a half without changing the membrane which took another 45 minutes. I watched my son who had purchased the Brondell first, took no more than 15 minutes to change all the filters. Another thing I've noticed is that Brondell is so quiet. I used to hear lots of gurgling noise from the other brand all the time and is annoying.
