Product used to come with some sort of lubrication for the o ring and does not any longer. Not sure why that changed. When changing filters can be tricky to get it so it doesn't leak. Make sure o ring is in correctly.
I have been using this filter for over 10 years. Easy to install and replace filter. The type of filter seem to improve each time, a little bit. I have not chosen upgrade to newer system as I have not seen any convincing need to upgrade.
Pros: Clean taste, Easy to clean, Easy to install
Cons: Not durable, Uses Lots of Replacement Filters
I use the filtered water for all drinking and cooking. I like how it takes the chlorine smell and taste out of the water. I have had a counter top model for quite a few years and I see no problems with it that I would feel people should know.
Best buy ever. Water is not only what you drink. It is also what you cook with or you wash your vegetables etc. This product is easy to use and at least according to its specifications it gives perfect filtration.
Pros: Clean taste, Durable, Easy to clean, Easy to install, Long lasting filter
