  • Conclusion:

The iSpring 75GPD is an under the kitchen sink reverse osmosis system, that includes five separate filters that water passes through to filter out over 1000 different impurities that can be in your water supply.  The system’s fourth filter is where the real magic of the system takes place, the reverse osmosis membrane which is  0.0001 micron(µm) effectively removes lead, chromium, copper, arsenic, salt and even parasitic cysts.  The way reverse osmosis works, is water is pushed through the membrane under pressure and only the water can pass through the small .00001 micron filtration medium, this same technology is used in bottled water production.

5 Filtration Stages:

The iSpring 75GPD Water Filtration system, works by having water filtered through five separate filters, before it reaches your dedicated water faucet.

  • 1st State

    Ever time you turn on the tap, your water first passes through a high capacity polypropylene sediment filter.  This filter works by removing all the large particles, up to 5 microns, including rust, dust and sediment.  This is important since it extends the life of the filtration system and removes the largest particles first.

  • 2nd Stage

    Next your water passes through the iSpring 75GPD’s 10 inch Granular Activated Carbon (GAC) filter.  This is where any odors such as chlorine, cloudiness and colors are removed.  It is important to note that this stage is fully compliant with NSF/ANSI standards.

  • 3rd Stage

    Next your water is filtered again through a 5 micron Carbon Block (CTO) cartridge, that removes any residual Chlorine tastes and odor from your water.  This is important since it greatly extends the lifetime of the other filtration cartridges in the system and gives you better tasting water.

  • 4th Stage

    The fourth stage is where all the magic of the system takes place, this is the reverse osmosis part of the system.  Where your water is forced through a 0.0001 micron High Rejection TFC Reverse osmosis membrane, which can remove up to 98% of over 1000 contaminants from your water supply. This super small micron membrane is the same system used at bottled water plants, because it is so effective and can remove even the smallest particles and contaminants from your water.  In total by this stage the system can remove up to 98% of Aluminum, cysts, ammonium, arsenic, asbestos, bacteria, barium, bicarbonate, boron, bromide, cadmium, calcium, chloride, chromate, chromium, copper, cyanide, detergents, ferrocyanide, fluoride, giardia, herbicides, insecticides, iron, lead, magnesium, sulphite, zinc, just to name a few minerals and contaminants from your water supply.

  • 5th Stage

    Finally your water passes through a 1 micron 10 inch polishing inline carbon filter, that removes and remaining residual tastes and odors.

 

Installation Of The iSpring 75GPD System:

One of the most frequent questions we receive is whether the average homeowner can install this under the sink water filtration system or if they will need to hire a professional plumber.  While the system with the various parts and tank may appear as a difficult DIY project, the fact of the matter is the average homeowner can install the system in about 2-4 hours.  The system includes an easy to follow instruction manual as well as online videos that guide the homeowner through the installation of the system.  Like most under the kitchen sink water filtration systems, the hardest part of the project will be drilling a hole through your counter top to mount the faucet and laying out the system and tank in your kitchen cabinet.  However, with some planning and preparation it is definitely a system that a homeowner can install themselves.  However, if you have any concerns you can always hire a licensed plumber or handyman to install the system for you.

When Do The Filters Need To Be Replaced?

The iSpring RCC7 reverse osmosis water filtration system, cartridges generally have to be replaced every six months.  The reverse osmosis filter or 4th stage filter can be extended up to 2-3 years based on usage and the 5th filter or polishing filter needs to be replaced every 12 months, the other three filters or 1st – 3rd stage filters should be replaced every six months.  We have provided an illustrated diagram below.  Though since the filters are sold as a set, most homeowners will replace all of the filters at the same time, every six months.
