Amazon.com This replacement cartridge for the New Wave Enviro 10-stage Premium Water Filter System produces a continuous supply of fresh, crisp, wonderful-tasting water right from your tap, removing major contaminants to below EPA minimum levels. The easily replaced filter produces approximately 1,500 gallons of water before it needs replacing -- enough to last a family of four for around a year.
