Multiple Stage Filter Performance…

The iSpring RCC7 comprise of 5 stages filtration system:
Stage 1: High Capacity 5 micron sediment filter – Removing dust, rust, sand and other contamination that normally can be seen by naked eye.

Stage 2, 3: 5 micron Activation Carbon Filter, Carbon Block  – Removing residual chlorine taste, odor and cloudiness,

Stage 4: 0.0001 micron Reverse Osmosis Membrane – Removing up to 95% of TDS in the water leaving a pure water behind. The heart and soul of the system. The water is stored into the tanks before it passes through the next filter.

Installation Is Easy….

Installation for iSpring RCC7 reverse osmosis system is pretty simple and straight forward. Following the user manual and the online video is sufficient to help you on the installation. There  might need additional drilling for the hole of the faucet and securing the water filter system under sink.

Tools that are required : Drill, drill bit for 1/2” and 1/4″, Pliers, Phllip Screw, Scissors

iSpring RCC7 Installation Flow

With the diagram above, it is pretty much self explanatory and easy to fix under sink. All the reverse osmosis system will need a drain pipe to channel the waste water out of the system.

I would highly recommend to channel the drain line to another storage tank for other purposes such as gardening, laundry and dish washing. Those are relatively clean water as they passed though 3 stages of pre filter before rejected by the reverse osmosis membrane.

Maintenance and Replacement Depending on Usage…

For iSpring RCC7, the replacement filter is quite frequent. The suggested lifespan of each filter are below :

  • Stage 1 – 3 Sediment and Carbon Block Filters: 3 to 6 Months
  • Stage 4 Reverse Osmosis Membrane Filter: 2 – 3 Years 
  • Stage 5 Post Carbon Filter: 1 Year 

It is all depends on the capacity of the water usage that you consume. You can always refer to the comprehensive troubleshooting guide in the user manual if you have any problem of the system. If the water pressure turns low, it might be a sign for you to look for a filter replacement.

Annual Maintenance Cost : $50

The Voice From Existing Owners….

As the iSpring RCC7 reverse osmosis system has been reviewed and used by thousands of customer, it is good to listen to some feedbacks from them on the pros and cons.

+ Installation is easy and straight forward based on the manual and online video.

  1. Great review, I usually just drink tap water and buy water bottles, which can get expensive at times. I am thinking about investing in a filter like this as I believe it will save me money, thanks for recommending this.

  2. I used to have a water filter in my old house back when I was living in Malaysia. It gave me a peace of mind to know that I was drinking clean water. The price for this iSpring RCC7 seems reasonable. How often does it need to be cleaned?

  3. Wow, this is a very thorough review. I really appreciate all the great info. I’m looking for a good filter to use and this looks like a top candidate. Ive been using a Brita water pitcher filter and I think I can get way better filtered water while saving money in the long run if I spend a little up front. Thanks again for your help.

    1. Yes, It’s time for an upgrade. At least you are still using Brita instead of drinking straight from the tap. You will never regret getting this model!

  4. I like your comprehensive review. A good filter is something I’ve been looking out for for a long time. Honesty its because my family is not so well informed about these that is solely the reason why we still don’t have one. Anyway your review helps and I think we are one step closer. Will continue to look out for more reviews from you. Let me know if there’s more available.

  5. Recently we got a scare back in my town…cholera! I mean where did it even come from?? thankfully the cases were just a few. I have become so conscious I cannot even wash my veggies in tap water lol a good tap water filtration is my top priority right now. I have a question, is the 3 months replacement time for the carbon filter a minimum regardless of the household size? Thanks

    1. It’s all depends on the usage of water. If you have a huge household (More than 8) in the house, you probably need to change it every 3 months. It is not a requirement to change it on time.

      To check whether it is time to change, use a TDS Meter to check on the TDS. If it fells below 70% of the TDS as compare to your tap water, it is time to change the filter.

  6. Hello there,

    That is a very thorough review of the iSpring RCC7 Reverse Osmosis System.
    I think that having a good and especially cost effective water filter is a must.
    The five stages of the filter performance are very interesting. I personally like the Post Carbon Filter since I hate it when there is an odour.
    Thank you for the awesome review.
