Filtration system and membrane

It comes with a 5 stage filtration system that ensures that even the tiniest of micro-organisms do not make it past its multi-level filtration system. This ensures that you get the best quality water with the least amount of pollutants and at a mere cost of one cent per bottle.

  • Stage 1: PP sediment filter that removes dust, sediment, and other impurities. Lifespan 6-12 months
  • Stage 2: GAC filter that removes chlorine, taste, and odors. Lifespan 6-12 months
  • Stage 3: CTO filter that removes chloramine and VOCs. Lifespan 6-12 months
  • Stage 4: RO membrane. Lifespan 2-3 years
  • Stage 5: Post-carbon filter for adding a “normal” taste and removing any residual impurities. Lifespan 6-12 months

The bigger RO membrane with more square footage allows for more delivery of up to 75 Gallons Per Day (GPD) of the same great tasting high quality water which is 1.5 more times compared to the 50 GPD.

This ensures that you always have a tank full of safe to drink water and when you are running low, the system is able to fill the tank in a shorter amount of time.

While such systems have the basic task of making sure that all the water that comes through them does not leave the same way it came in, it is also vital to understand that different users have different applications.

That is why this particular filtration system comes with a number of upgrades as of September of 2014. These include among others, a luxury designer EU style faucet, water detector as well as a Feed Water adapter among others.


Installation tips

The iSpring RCC7 requires a pressure of 40 to 80 PSI to function properly. If your water pressure is less than 40 PSI, you’ll need a pump to increase the pressure, and if the pressure is greater, you’ll need a pressure regulator.

On the whole, the installation process is really simple. Like most of the other systems we’ve reviewed, it takes 60 minutes or so to install and requires minimal drilling. You can always call a professional if you are uneasy doing it yourself.

You need to drill a single hole in your kitchen counter to pull the faucet through and mount. Drilling the hole will depend on what kind of material your countertop is made of.

The video we’ve embedded above is from iSpring themselves and it’s a very straightforward demonstration of how to set up the iSpring RCC7 system.


  • With the 5 stage filtration process, there is little chance of anything below the standard passing through guaranteeing the user of higher quality and safer water for their home use.
  • The system takes a shorter time to fill up a tank and hence makes it ideal for larger family and even better for a medium size family.
  • It is quick and easy to set up with a very informative video on YouTube on how to go around the process making it stress free right from the start.
  • Comes with a number of highly attractive packs that include a 30 day money back policy, 1 year satisfaction guarantee as well as free lifetime tech support.
  • This system has a 4 gallon pressurized tank
  • The faucet is European inspired with a nickel finish


  • For this system to work, the water pressure needs to be at least 40 psi and hence poses a challenge to areas with low water pressure since a booster pump is only available at an extra cost.
  • Waste water is the same as all systems: about 3 gallons per gallon of purified water
  • Shorter filter lifespan than similar models

iSpring RCC7P: an upgraded iSpring RCC7

Since we mentioned that one con of the iSpring RCC7 is the lack of a pump, there is another model available which is an improved version of the iSpring RCC7: the iSpring RCC7P.

The RCC7P has a permeate pump built in so you can use it even if the water pressure in your home is below 40 PSI.

It also produces less waste water than the original model.

Overall, the iSpring RCC7 is a very competitive RO system that’s right up there with the APEC Top Tier. One potential shortfall though is the filter lifespan. However, it’s worth noting that iSpring replacement filters are also more economical than other systems.

Also, there is no LED indicator to let you know when to change a filter, so you’ll just have to periodically measure the TDS to check the integrity of the filters.

Still, the price is quite appealing, and considering the lower cost of the replacement filters, the iSpring RCC7 is one of the better value systems out there.

    I bought this reverse osmosis filter on amazon, and it’s really good. I isntalled it myself, while my buddies were watching the superbowl. It wasn’t easy, but I managed to get it all setup without too much damage to the house.

    When I used a TDS tester to compare it to tap and filtered water, and the ro filtered water had no weird taste, and tested at 9 TDS. On the other hand, the regular tap water, was tested at 42 TDS, and tasted gross.

    Before this system, our regular tap water was measured at 300 to 400 TDS range, but now it’s even better.

    So far pretty happy with it.

    Water quality is very important if you’re an aquarium lover like me, and I started looking into reverse osmosis systems when I upgraded to a larger aquarium a few months ago. The price for this system is more than reasonable, and it actually delivers great results for the price. A few things to note: it only has about a 2.5 gallon capacity, so this thing isn’t going to filter enough water for your entire house at one time. However, it’s great for aquarium usage. I didn’t think I’d be able to get something that works this well for under $200.
