Product review (3 stars): Not Perfect But Not Bad
The first cartridge I installed worked for a few days and then sprung a leak of about a cup of water a day.  At first I thought it must have been water that leaked out during the exchange of filters.  However, after cleaning it up and then a couple days later everything was standing in water again in the drawer below the filter, I finally figured out what was leaking.  I replaced that filter with another from the same shipment and it has not leaked at all for several weeks now.  I've used this brand for several years, ordering them on-line, without any problems.  This was the first.
