Product review (4 stars): Good filter, but not quite a factory fit in my LG
Seems to filter fine, fits and does not leak.  However, it is not an exact replacement for the LG factory filter in that it would be much easier to jar this one loose from its mount.  The factory filter is shaped to engage some dogs on the housing and "click" into place as you twist it.  This filter lacks that feature and can be released by turning it with very little force.  Not sure whether I would buy it again, but the cost savings is compelling if it holds up as well as the factory filter.
