Product review (5 stars): OEM LG water filter
The LG refridgerator requires a new water filter around the 6 month time frame.  The LG requires that you either have this filter, or use the bypass insert if you don't want or need to filter your water in your fridge.  The filter itself seems to "clean up" some the the strong chemical taste of chlorinated water from a city supply.  The only thing I don't like about this LG system, is that it requires you to dispense 2.5 gallons of water through the filter before actually using the filter.  I can understand the science behind that, because you need to ensure the filter is soaked and all the by-products are washed out from manufactoring.  What I find a little annoying is that LG recommends only depressing the water for 15 seconds at a time, and then waiting 60 seconds to start the water flow again.  It takes a while to get 2.5 gallons of water through this process, which means you spend like 20 minutes standing in front of your refridgerator filling up jugs.  In any case, I do like using the filter because it does help with the taste of the water.
