The iSpring RCC7D is an RO deionization filtration system specially designed for anywhere that ultra-pure water with zero total dissolved solids (TDS) is required.

It provides complete water purification via six individual filtration stages that include a specially manufactured deionization (DI) resin filter which makes a superb option for either aquarium use or drinking water.

Filtration Process

The early filtration stages of the RCCD7 are the same as the RCC7 and the other iSpring RO systems.

The five stages feature the 3 carbon pre-filters that capture large contaminants and volatile organic carbons in the water. They as well ensure chlorine, chloramines, and other chemicals are removed in the water ahead of the RO membrane.

The TFC RO membrane completely removes all the contaminants that are larger than 0.0001 microns while the fifth stage coconut shell post-filter further captures any residual chlorine and chloramines that sipped through the RO membrane.

Deionization Filter

The last stage of the iSpring RCC7D is the specially designed deionization resin filter and it’s what sets this model apart from most other similar systems out there.

It’s a super-efficient deionization post filter which completely removes the total dissolved solids (TDS) in the filtered water that the RO membrane could not capture.

It effectively uses ion exchange resins to clear all the dissolved contaminants bringing the water to 99.99% purity with close to 0 ppm TDS.

In other words, it delivers the purest water possible, even purer than distilled water which makes the iSpring RCC7D ideal for use in aquariums, laboratory testing, and cleaning.

The water produced by the system is also safe for drinking, but considering that all the TDS and minerals are completely removed, it may taste plain or unpleasant to most people.

However, if your tap water is hard and you don’t mind the taste, then you can certainly use this system to soften your tap water hardness level and produce clean and highly pure drinking water.

Filtration Capacity

With regards to filtration capacity, the iSpring RCC7D will give you a maximum of 75 gallons of clean water per day which is sufficient for larger freshwater aquariums, reef aquariums, and fish breeders.

It’s as well enough for small to medium-sized families if you are using it for drinking water. It wastes around 2 gallons for every gallon of water it produces, so it’s equally quite efficient.

Installation and Maintenance

The installation process for the iSpring RCC7D can be a bit confusing but the instruction manual is clear and well organized plus there are videos that guide you through the process. All the parts are included and the unit is small enough to fit under most standard kitchen sinks.

In general, we would highly recommend the iSpring RCC7D to anyone who is looking for a system that can give them the purest water with almost zero TDS value.

The combination of the RO filtration process and the deionization filter will absolutely give you clean, clear and water with maximum purity possible ideal for your aquarium or drinking.
