APEC RO-45 system, you like?
We have a GE Profile from Home Depot that replaced another brand we had for at least 10 years. It works well except that we have to change the 2 filter cartridges more often than we'd like, about every 4 months. We change the RO cartridge about every 6 months. The 2 filter cartridges run about $50. Sometimes I wonder if using a Berkey filter would be less expensive plus we wouldn't be running all that extra water down the drain. Just have to convince DH of that.
BTW, nice name.
... You like my name?? Your name Erin???
