We’ve had a reverse osmosis filtration system from Culligan for a couple of years and we just love it! It’s so convenient, we don’t have to change the filters ourselves, they come out once a year to switch them out. We recently had a problem with the sink filtration faucet and I called Culligan and they promptly sent out a technician to replace the faucet! We are so happy with them and the great service they provide, I would highly recommend them to friends and family!
