I have problems with this filter probably 2 times out of 3 during installation. I've tried third party vendors and they're just as bad if not worse. It's just not worth the effort. I'll look into reverse osmosis filtration, maybe that's less of a problem. EDIT: I changed my newest filter before because the "broken glass" noise came from the filter when I unpacked it. I installed it anyway and the water came out black. I have received a replacement. The replacement doesn't have the sound of broken glass, but the water isn't black now, but definitely not transparent (compared to tap water). If I could give this product zero stars I would. I should now check with Revain to see if this second one can be refunded as I won't be messing around with this junk anymore. I am done with this company and their products. It is surprising that they cannot properly perform the main function of the filter - water purification.
