Product review (1 stars): Getting two for the price of one is twice as bad
Two filters priced at about half the cost of others arrived quickly, but were considerably lighter than other refrigerator filter replacements.  Perhaps that is the reason why the label indicates each one is only good for 300 gallons, which is significantly less than other brands. The filter cartridge leaked even after I applied silicone grease lightly to the gaskets.  It took repeated attempts to install and re-install to get the connection to be leak-free. Meanwhile, we had to sop up a lot of water in the fridge. Never had this problem like that with other brand filters.  Then about two quarts into the first "flush" a lot of black carbon regurgitated into the dispensed water.  It cleared after a gallon or two more flushed.  I don't feel very confident about this product and will not buy it again, especially since there are so many other choices available.
