Although reverse osmosis is the most effective method of removing contaminants from water, it has one major flaw – removing essential minerals like calcium and magnesium from the water.
The best way to restore the minerals and improve the pH of the water is through remineralization.
If you find reverse osmosis water boring, you need to invest in the best reverse osmosis system with remineralization. The process makes the water healthy and great tasting.
And since getting one for your household might not be easy, we’ve prepared this post to guide you through.
We’ve discussed the top 5 RO systems with remineralization to help you make an informed buying decision. Keep reading

1. iSpring RCC7AK-UV 7-Stage RO System
Check Price on Amazon
The RCC7AK-UV is a premium quality RO system that filters water in 7 stages. The model is a product of iSpring; a water filtration solutions brand with headquarters in Atlanta, Georgia.
The multi-layered system removes up to 99% of over 1,000 water contaminants, including heavy metals, microorganisms, chemicals, and more.
It produces 75 gallons of water per day and has a filtered-to-waste water ratio of 1:3
Eager to know why the RCC7AK-UV is one of the best RO systems with remineralization? This is why:
Impeccable filtration performance
The system features some of the longest-lasting filters in the industry that filter water progressively in 7 stages.
In the 1st, 2nd and 3rd stages, the unit uses 3 pre-filters, including the PP sediment filter, carbon KDF (GAC) filter, and the carbon block (CTO) filter to remove sediment, chlorine, and chloramines.
Next, the water moves to the system’s heart (RO membrane filter), which eliminates contaminants down to 0.0001 microns.
In the 5th stage, a fine GAC filter further polishes the water before it is delivered to the faucet.
And to restore the removed minerals and add taste to the water, an alkaline remineralization filter comes into play in the 6th stage.
This system features an additional filtration stage – the UV stage that eliminates viruses and bacteria that could be present in the water.
Reinforced transparent first-stage housing
With the transparent housing, you can always tell when the filter is due for replacement.
High-quality components
The RCC7AK-UV is one of the most reliable and low-maintenance systems thanks to its premium quality components.
Easy DIY Installation
The system comes with push-connect fittings and color-coordinated tubing that makes installation easy. You do not have to be a pro to set the unit up.
Certified to NSF/ANSI 58
All filters, tubing, tanks, and other water-contacting parts are NSF/ANSI 58 certified for TDS reduction.
Unique flow sensor switch
The switch turns the UV unit on and off automatically. This helps save power and lengthen the life of the UV lamp.
Pros
- Has a UV filter
- Outstanding filtration performance
- Fast flow rate of 75 GPD
- Well written instructions
