My husband and I purchased the Alexipure water filter about a year ago. I have been very satisfied with it. We have some very hard water and it has been going strong with no issues. The design is well thought out and is not complicated to use. There is no need for electricity with this filter, as it is all gravity fed. It does take up counter space but so does any alternative water filtration method we employed. You can fill it with tap water or lake water, it can handle it all. The only downfall I could even think of is the fact that you need to keep the filter moist in order to maintain its viability. All that means is you need to use it. Great product, highly recommended.
