iSpring F21CRO1000 4.5'' x 20'' 4-Stage Tankless Commercial Reverse Osmosis Water Filter 2-Year Replacement Cartridge Pack, 21-Piece

About this item

• Individually wrapped, 2-year high-capacity, top-quality filter replacement cartridge pack for iSpring CRO1000 and standard housings that use 20’’ x 4.5” water filters.
• Sediment Water Filter: The first stage high-capacity polypropylene sediment filter works as the first barrier in the reverse osmosis system by removing solid particles like silt, rust and dirt from the water and reducing a significant percentage of contaminants in the water. This prevents the other filters from getting clogged with fine particles and reduces the risk of damage to the other parts of the filtration system.
• Carbon Block Filter: The second and third stage CTO Carbon Block filters are made of coconut shell carbon to increase filtration efficiency and extend filter life. Activated carbon filters trap and absorb chemicals and chlorine from the water. This results in the removal of odors and an improvement on the taste of the water.
• 1000 GPD RO Membrane: The fourth stage RO membrane removes up to 99% of over 1,000 contaminants, including lead (up to 98%), chlorine, fluoride, arsenic, asbestos, calcium, sodium, and more. The core of CRO1000 beats contaminants, delivering clean water at a rate of up to 1,000 gallons per day. Operating at 80 - 130 psi, it achieves an exceptional 1.5:1 pure-to-drain water ratio, enhancing efficiency and reducing water bill costs.
• Twenty-one 20” x 4.5” replacement water filters included: 12 Sediment Filters, 8 Carbon Block Filters and 1 RO Membrane.
