Detailed Breakdown


Though the iSpring RCC7AK-UV has some good features, we wanted to look at the seven stages of filtration that it does first because this is more than you get with similar systems. In addition to the standard six stages, it comes with an alkaline filter that works with a UV bulb to sterilize and clean the water. If you notice particles coming out of the tap, this will eliminate them.

With the fine filter, this system works on tiny particles that you normally can't see and the larger substances too. It catches any of the particles that usually reach the tap and catch them in a separate filter. Those filters work together to give you water from the tap that tastes just like bottled water.


  • Brushed-Nickel Faucet Included That Is Lead-Free
  • 3.2-Gallon Tank With A Holding Capacity Of 2.5 Gallons
  • Alkaline Filer With Sterilization Bulb Included
  • Filters Up To 75 Gallons Of Water Per Day
  • 1: 3 Ratio Of Filtered To Wasted Water
  • Measures 15 X 8 X 18 Inches


Before you install and set up the RCC7AK-UV, we highly recommend that you read through the instructions and make sure that you understand what you need to do. Some people who used this system had problems installing it and had a difficult time getting in touch with iSpring customer support reps.

Though some also found that the UV bulb died sooner than they thought it would, most users recommend the RCC7AK-UV to others. It is a reliable system that is easy to use.


Most of the home water filtration systems retail for around the same price point. You can get the RCC7AK-UV from iSpring for a little more than you would pay for a basic system that uses six stages of filtration. That extra stage of filtration gives your water a cleaner and more refreshing taste.


A water filtration system is a must-have for anyone who has well water or city water. The RCC7AK-UV goes a step further than the standard six stages and uses an additional filtration stage that sterilizes the water to remove the acid in your water and any impurities. This gives you soft water without using a water softener.

This is also a smart filtration system for homes with acidic water or water with a high alkaline level. As you can install the RCC7AK-UV and put the entire system together yourself, it's an easy project for you to finish on a weekend or a day away from work.

Our Opinion

Buying bottled water can cost you more in a single month than you want to spend, but the iSpring RCC7AK-UV Deluxe Reverse Osmosis System can recreate the taste of that water in minutes. It does this through seven filters that include an additional sterilization filter that sanitizes the water and makes it safe for drinking.

Capable of moving lead, fluoride and more than 1,000 other impurities, the RCC7AK-UV works with water that comes from the city or a well. Thanks to our review of the iSpring RCC7AK-UV Deluxe Reverse Osmosis System, you can easily see why we recommend it to our readers.

Other Options Worth Looking at

One of the leading competitors to the RCC7AK-UV is another model from iSpring called the RCC7AK 6-Stage Superb Taste High Capacity Under Sink Reverse Osmosis. It only offers six stages of filtration rather than the seven stages found on the main model and may not remove as many potential toxins as you expected. You may find that the water has a slightly acidic taste that comes from the filtration too.

Another option is the APEC Top Tier Alkaline Mineral pH+ 75 GPD 6-Stage Ultra Safe Reverse Osmosis Drinking Water Filter System, which has six filters that your water passes through. Though it removes up to 99% of the contaminants you want eliminated, it can reduce your water pressure down to 40 psi. If you want a higher water pressure, the RCC7AK-UV is a better choice.
