The last time we replaced this cartridge my dis-belief -was 10/08. My wife was the first to mention the water in her bottle has been tasting a little off, just this week. This OMNI water filter is a Great one and so simple to replace the cartridges. Whats More, Filter Fast hasn't changed their prices in over 8 years! Cant wait to try their MERV11 furnace filters. Thank You for being 'Customer Responsive'.
