Product review (1 stars): Poor substitute
Got these filters as the LG brand ones are so darn pricey.  I'll use them for a while, but I really don't think that they are filtering that well. They seem to get out the chlorine taste so must have some amount of charcoal in them, but my water flow rate is so much faster that they can't be filtering that well.  There was no data sheet with them (the sheet that tells you how many microns of this, that, and the other that it filters) so that's pretty telling. Next time I'll buy the brand name ones, or at least a substitute that has a data sheet.
