What impresses the most is the reinforced transparent first stage housing that lets you inspect the sediment filter and watch how contaminants are removed from the water (purple casing).

What to Consider before Buying the iSpring RO 7 Stage Water Filter

Pollutants removed

iSpring RCC1UP AK 7 stage ReviewThe iSpring RCC1UP AK 7 stage is capable of removing up to 99% of pollutants present in water including but not limited to:

  • Sediments Total Dissolve Solids – TSD (up to 750 ppm).
  • Heavy metals such as lead, mercury, cadmium, zink between others.
  • Chlorine, choramine, fluoride, organic and inorganic compounds, odor, taste.
  • Bacteria, viruses and harmful spores (micro-organisms).

Lastly, this water filter will improve the water taste by adding important minerals that your body requires daily.


With a filtration capacity of 1000+ contaminants, the iSpring RCC7AK reverse osmosis filtration system counts with 7 stages including filters and additions (alkalinity):

  • Stage 1: Model FP-15 five (5) micron sediment filter (polypropylene) to remove also dust and rust. Life times is from 6 to 12 months.
  • Stage 2: Model FG-15 five (5) micron Granular Activated Carbon (GAC) to remove chlorine, odor color and taste. Lifetime between 6 and 12 months.
  • Stage 3: Five (5) micron Carbon block filter (CTO), which will remove chloramine, volatile organic compounds (VOCs), chemicals and others. 6 to 12 months lifetime.

GAC and CTO trap large and small contaminants alike.

  • Stage 4: Great Well Reverse Osmosis membrane (main stage) model TFC-2012-75. This RO model has a 2-3 years lifetime.
  • Stage 5: Model FT-15 post carbon filter (polished carbon) to ensure the removal of any taste or odor coming from the tank. Lifespan between 6 to 12 months.
  • Stage 6: Alkaline filter model FA-15 adding minerals that your body needs; also helps to balance the water pH. Expected lifetime from 6 to 12 months.
  • Stage 7: Kills microorganisms (viruses, bacteria and harmful spores) using UV activation when the system detects water flow (it shut-off when there is no operation, saving energy). It is expected 1 year use.

The filters lifespan mentioned above is what the manufacturer suggested for filter replacement. Off course, the more you use the filters the sooner you will have to replace them but not below 6 months expectancy.

Operation & Maintenance

iSpring RCC1UP AK partsThere is not much we can say about the operation of the RO iSpring RCC1UP AK 7 stage other than doing the connections to the main water hose into the first filter/stage, then the whole system will do its job. Nevertheless, the iSpring reverse osmosis installation is advertised as DIY but a little too complex for homeowners with basic handyman skills.

What is important to know is that:

  • You will have to have a water pressure above 45 psi, which is covered by the booster pump included with the system.
  • Enough space underneath you kitchen’s sink.
  • A power source to connect and operate the UV filter.
  • This is good for homes sourcing water from private wells or river streams.
  • Your water source needs to have a maximum TDS of 750 ppm. Anything above this number will dramatically reduce the lifetime of the filters and affect the RO membrane.

Regular maintenance involves cleaning up and replacing the filters every six (6) to 12 months and 1 to 3 years for the RO membrane and UV filter.

Able to remove most contaminants, easy to install, and dependable, iSpring reverse osmosis water filter is a great water filter that brings real value for money.
