5-Stage Under Sink Reverse Osmosis Water Filter System
The 5-stage reverse osmosis system uses reverse osmosis (RO) membrane to remove over 1,000 contaminants like PFAS (PFOA and PFOS), vinyl chloride, chlorine, lead, fluoride, asbestos, sodium and more. Even if the city already filters your water, contamination can still occur during transportation, such as in areas with lead pipes, which may pose health risks, along with possibility of underground pollutants contributing to water quality concerns. Therefore, incorporating a point-of-use reverse osmosis (RO) water filtration system adds an extra layer of protection for you and your family. With almost 20 years of expertise in water filtration, iSpring has created a variety of 5-stage RO filters for homeowners. Our filtration systems are designed with quality components to provide filtered water for the long term with minimum maintenance.
Finding the Right 5-Stage RO System for Your Home
Our options represent a range of features, ideal use cases and price points to fit any household's needs. Our filtration systems include:
- RCC7 A reliable 5-stage RO system designed to ensure your water is clean and safe to drink. With a 75 GPD output and NSF/ANSI 58 certification, it's trusted for its exceptional quality and performance.
- RCC7P It has a 75 GPD output and comes with a built-in pump that boosts water pressure up to 80 psi. Perfect for places with low water pressure (<45 psi), it enhances filtration efficiency and reduces waste water.
- RCC100P Equipped with a pre-installed pump, it produces water faster than the RCC7P, boasting a 100 GPD output.
- RO100 A 5-stage RO system featuring US Made filters. With upgraded 3/8” input and output design, it offers a 100 GPD output for reliable water filtration.
How Does a 5-Stage RO Filtration Work?
The five filtration steps include:
- Polypropylene (PP) sediment: The PP sediment filter removes rust, dirt, particles, sand, dust and other microscopic sediments from tap water. This stage prevents the rest of the filtration system from getting damaged or clogged from sediment buildup.
- Granular activated carbon (GAC): GAC is a carbon prefilter that removes undesirable odors and tastes and improves color and turbidity. Removing chlorine during this stage protects the RO membrane from chlorine damage.
- Carbon Block (CTO) Filter: The CTO filter removes any remaining chlorine and odor to improve your water's taste and smell.
- RO membrane: It removes contaminants down to 0.0001 microns to make your tap water the same quality as bottled water.
- Post carbon: The final step removes any residual odors and improves the taste of the water.
