I have read other reviews that say this product does not clean heavy stuff from the water as expected. I have used other products that give results that require changing more often and used 3 steps to filter out contaminants. They were expensive and troublesome, without the best taste. I don't think bottled water is any better than tap water. All I'm hoping for from this product is that it moves anything over 0.5 microns. My house has normal water pressure. There was no noise or vibration.
