I love my WaterWise still! It's a great design and well built. I've been using mine for 6 or 7 years now and all I had to do was change out those filters and a couple of o-rings. Activated carbon filters fit and work well. However, the filters are a bit more expensive and it took almost a month from ordering to actually receiving the product. I will try refilling/recycling the filters myself with activated carbon from the homebrew or aquarium store. It would be a lot cheaper and I wouldn't have to wait as long
