iSpring FWDS150K high capacity 20” x 4.5” water filter replacement cartridges - anti scale filter with patented scale inhibitor - fits standard 20” x 4.5” whole house water filtration systems - Pack of 1.
Protect your household appliances and plumbings from scale: the patented scale prohibiter effectively sequester calcium and magnesium, preventing your pipes from scale and clearing partially clogged piping
Our premium filter media inhibit corrosion, particularly iron, steel, galvanized, copper and lead, by coating the surface of your pipes
The coating also helps to stabilize chlorine as the chlorine will not react with the metal pipe if the coating exists
The filter is made of patented scale inhibitor and is capable of filtering up to 150,000 gallons of water, or lasting for 12 months (depending on inline water quality)
The filter is tested by an independent third-party to meet NSF 42/60 standards
Peace of mind customer service: the product is backed by a 30-day money-back warranty, 1-year manufacturer warranty, and extended warranty upon registration
Lifetime tech support is available online or by phone from Alpharetta, GA, USA
Please note: unlike an RO system, this system will not reduce total dissolved solids (TDS), and instead keeps healthy minerals in your water
If you are interested in a filter that removes TDS, consider our iSpring reverse osmosis (RO) systems
