The filter we purchased did not work correctly.  We would get a good stream of water for 4 seconds and then it would run extremely slow.  We read some ways to fix this on google so we tried a few.  We were able to get it to work good for about 3 weeks and then it started to do the same thing again.  We removed the filter and just use the plug now and have not had an issue.  We are not getting filtered water but at least it fills our glass fast.
