iSpring RCC7AK Review {Updated May 2024}

The iSpring RCC7AK Water Filter provides excellent value for money for a 6-stage RO system. If you compare this model to brands like APEC, it offers a dramatic long-term saving. It also provides a somewhat low waste to water ratio for environmentally-conscious consumers. But perhaps the best reason to invest in this brand is the fact that iSpring listens to what customers need and continually strive to make improvements to their systems.

iSpring RCC7AK – Features And Benefits

The iSpring RCC7AK is a 6-stage reverse osmosis water filter designed for residential homes. The primary selling features of this system are the alkaline filter and its price. The RCC7AK is affordable and offers impressive value when it comes to 6-stage reverse-osmosis systems.

This unit offers a 75-gallons per day water-production rate, along with a reliable alkaline filter. These are generally features that typically cost much more in other similar models. iSpring also offers lifetime customer-support provided by certified professionals.

The iSpring RCC7AK Water Filter uses an alkaline filter that restores minerals that are usually removed during reverse osmosis processes. This means that calcium and magnesium are returned to the water once it is stripped away. However, this system does not come with a pH monitor or any other way to measure the levels of minerals that are added back into the water. iSpring does advertise that you will achieve “great-tasting water” while suggesting that this particular model translates into water only costing around 2-cents per bottle.

Another advantage of this model is that it removes up to 99% of contaminants, which is the standard figure suggested by many other brands. However, the overall effectiveness usually depends on the water quality source, temperature, and pressure. Reverse osmosis is still regarded as one of the top methods of water-filtration for homes.

This process effectively removes most of the common contaminants, while protecting against other toxins such as pharmaceuticals and pesticides. This form of protection is usually only improved once you add a UV filter to these systems. This option is available at an added cost but is successful in removing harmful bacteria that may be present in the water.

Perhaps the most beneficial aspect of this particular RO Water Filter has to do with its function and design that was upgraded and reviewed in 2014. After considering customer feedback, iSpring decided to make improvements to the shut-off valves and the storage-tank, along with making upgrades to the 5th-stage carbon filter. The commitment of this company is something worth taking into consideration if you are deciding to invest in a reverse osmosis system for your home.

The iSpring RCC7AK also features other upgrades like the brushed nickels, designer faucets, and ceramic valves (these upgrades are available at an added cost).


  • Value for money
  • Larger RO membrane that translates into quicker water production
  • Perfect for large households


  • The pH filter is not 100% efficient
  • It is not effective in replacing all the minerals lost
  • Does require DIY skills for the installation

Reverse osmosis systems are still one of the more effective methods used for home-water filtration. However, these systems do come with a few drawbacks, one of which is that they will usually only filter your water from a single drinking point (typically the faucet in your kitchen). If you are looking for filtered water to supply all the plumbed points in your home (including your bathroom), it is better to invest in a whole-house water filtration system.

What Are You Getting For Your Money

In addition to water that tastes great with a pH balance that is more natural, this product comes with all the parts you will need for a successful installation. The package includes the storage tank, which holds 3.2 gallons-of-water, the faucet that attaches to a sink, and all the parts and attachments needed.

Does The iSpring RCC7AK Come With Any Certifications?

This model is a WQA Goal Seal certified product. Since it is certified for the NSF/ANSI Standard 58, you can be sure that these models are made from premium materials and will perform as advertised.

Reasons To Buy The iSpring RCC7AK

The iSpring RCC7AK is an effective, well-designed, and well-made product. These systems are also relatively easy-to-maintain and easy-to-install (provided you have a few DIY skills). It also comes with a 1-year warranty and an impressive WQA Gold Seal certification along with lifetime customer-support provided by a team of certified professionals.
