This cartridge replaces the discontinued AP917R.
The Aqua Pure AP917HD is a replacement cartridge with proven credentials. It has the reputation of being excellent at removing particulate, dust, and the taste & odor of chlorine from drinking water. This is a granular activated carbon cartridge that ensures years of hassle-free performance along with the ability to keep away the hard water salts. It protects pipes and equipment against scaling. The capacity is rather impressive at 100,000 gallon which ensures you are never short on clean, odorless water. This feature engages more attention with the promise of at least a year of issueless performance. The AP917HD has a 304 stainless steel head that allows for "sweat in place" installation. It uses a sturdy, corrosion-resistant material. The filter has a 1" inlet/outlet connection for easy installation. The flow rate is rather impressive at up to 20 gpm (75.7 lpm). The Aqua Pure AP917HD comes with a 25-year limited warranty on the stainless steel head.
