iSpring F6K75 Under-Sink Water Filter
The iSpring F6K75 is a 6-month replacement filter set for most standard under-sink 6-stage reverse osmosis systems. This complete filter pack provides half a year’s supply of high-performance filtration.
The F6K75 includes:
- 1 x sediment filter
- 1 x granular activated carbon filter
- 1 x carbon block filter
- 1 x 75 gpd RO membrane
- 1 x post carbon filter
- 1 x alkaline remineralization filter
These filters work together to remove contaminants while improving water taste and quality:
- The sediment filter (5 micron) traps dirt, sand, and particles.
- The granular activated carbon filter absorbs impurities and chemicals.
- The carbon block filter polishes the water by capturing smaller particles.
- The reverse osmosis membrane (75 gpd) filters out heavy metals, chemicals, bacteria and more.
- The post carbon filter removes any remaining odors or tastes.
- The alkaline remineralization filter adds back healthy minerals and balances pH.
The end result is cleaner, healthier, better tasting water – even exceeding the quality of bottled water. The 6-stage filtration process removes up to 99% of over 1,000 contaminants while retaining beneficial minerals through alkaline remineralization.
The quick-change filters make maintenance simple. The F6K75 is compatible with most standard under-sink RO systems that use 10″ x 2.5″ cartridges. With proper filter changes every 6 months, you can enjoy contaminant-free water from every tap.
iSpring F9K Reverse Osmosis Water Filter
The iSpring F9K provides 1 year’s supply of replacement filters for 6-stage reverse osmosis systems. This convenient filter pack includes 9 high-performance cartridges to filter water for an entire year.
The F9K contains:
- 2 x sediment filters
- 2 x granular activated carbon filters
- 2 x carbon block filters
- 1 x post carbon filter
- 2 x alkaline remineralization filters
Together, these filters remove impurities while improving water taste and quality:
- The sediment filters (5 micron) trap large particles.
- The granular activated carbon filters absorb chemicals and chlorine.
- The carbon block filters polish the water by trapping smaller particles.
- The post carbon filter captures any remaining odors/tastes.
- The alkaline filters add healthy minerals and balance pH.
This results in clean, contaminant-free water with an improved taste. The multi-stage filtration process reduces chlorine, chemicals, heavy metals, bacteria, pharmaceuticals, and other impurities.
The remineralization filters also add back beneficial minerals like calcium and magnesium. This balances the pH while enhancing the flavor. The end result is delicious water exceeding bottled water quality.
The F9K simplifies maintenance with quick-change filters. It is compatible with most standard 6-stage RO systems that use 10″ x 2.5″ cartridges. Just replace the filters once a year and enjoy clean water from every faucet.
iSpring F3WGB32BM Whole House Water Filter
The iSpring F3WGB32BM is a 3-stage whole house water filtration system for well water. It reduces common well water contaminants for cleaner, better tasting water from every tap.
The 3-stage system includes:
- 1 x sediment filter
- 1 x carbon block filter
- 1 x iron & manganese reducing filter
Together, these filters improve your home’s water in the following ways:
- The sediment filter (5 micron) removes sand, dirt, and particles.
- The carbon block filter reduces chlorine, chemicals, and odors.
- The iron & manganese filter eliminates metallic tastes and stains.
This process makes well water safer and better tasting for whole home use. The triple filtration removes sediment while reducing iron, manganese, chlorine, chemicals, and other contaminants.
The system connects easily to existing plumbing. It works with standard housings that use 20″ x 4.5″ cartridges. With a flow rate up to 15 gpm, it has minimal impact on water pressure.
Each filter lasts 6-12 months depending on water quality and usage. Just replace the cartridges once a year and enjoy cleaner water from every faucet and appliance. Improved filtration protects plumbing too.
iSpring 5-Micron Whole House Water Filter
The iSpring FP25B is a set of two 5-micron polypropylene sediment filters for whole house systems. As the first stage of defense, these filters trap dirt, sand, and particles that can damage plumbing and appliances.
Made of durable polypropylene, these filters work in the following ways:
- The 5 micron rating traps sediment and particles down to 5 microns in size.
- The inner spiral pattern maximizes surface area for improved water flow.
- The multi-layered density filters out particles of all sizes.
Together, the filters protect your home’s plumbing and water-using appliances. By trapping sediment, they prevent scale buildup and clogging of faucets, showerheads, and appliances like washing machines.
The FP25B filters easily connect to standard 20″ x 4.5″ housings. With a high dirt-holding capacity and flow rate up to 15 gpm, each filter lasts 6-12 months depending on your water quality and usage.
For optimum performance, change the sediment filters once a year. Then enjoy cleaner water flowing freely through plumbing fixtures and appliances.
