The models in the APEC ultimate series are all WQA gold seal certified systems which means they guarantee the highest standards and contaminant removal rates in the industry.
Besides the certification, what puts them ahead of the essence series models are there high-performance filters and larger capacity.
As one of the flagship system in the ultimate series, the RO-90 provides great performance and results with about twice the amount of purified water that you would get with any standard reverse osmosis unit. It’s a serious consideration for large families with a high demand for water.
The filtration process of the APEC RO-90 system involves 5 stages featuring super-effective filters and membrane.
Composed of a quality polypropylene sediment filter, the 1st stage of the system removes particles in the water like rust, dust, sand and silt down to 5 microns. The 10” filter has a large dirt holding capacity which makes it more durable and efficient in filtering out the sediments.
The 2nd stage is fitted with also a quality 5-micron carbon block filter that can remove chlorine, chloramines, VOCs, unpleasant odor, taste, color and most other chemicals present in the water.
Another similar 5-micron carbon block filter sits in the 3rd stage and it takes care of the remaining chlorine, VOCs and chemicals that passed through the second stage.
The two carbon block filters have particles of carbon made of coconut shell and fused into a homogeneous region. Their large surface area and effective coconut shell carbon media ensure optimum contact time which boosts their absorption ability.
Stage four features APEC’s high-rejection 0.0001-micron FILMTEC RO membrane which performs rigorous filtration that eliminates even the tiniest contaminant molecules in the water.
Certified by the WQA, this high-quality membrane will filter out up to 99% of all TDS and contaminants including bacteria, viruses, heavy metals, fluoride and much more.
In removing the residual taste that often arises from the RO holding tank, the APEC RO-90 is equipped with an advanced coconut shell TCR (Total Contamination Removal) filter. This post-filter refines the RO water eliminating every remaining taste and odor from the tank.
Filtration Capacity and Efficiency
While the superb performance of the RO-90 is commendable, its high water production capacity is as well a major factor that has made it an attractive option on the market.
The unit can generate up to 90 gallons of purified water in a day which is amongst the biggest capacities available for residential under sink RO systems.
This great capability to produce a lot of water make this model absolutely perfect for any large household and family that often consume more than 50 gallons per day.
Moreover, the high capacity filters help facilitate a much faster flow rate and filtration, about twice faster than standard RO systems. Therefore, you will be able to draw much more water from the unit within a shorter time. It’s ideal for filling those large pitchers.
The only downside though is that like most of the other systems from APEC, this system is set to use 3 gallons of water to rinse out the contaminants for every one gallon of pure water produced. So, there’s no improvement with regard to filtration efficiency.
Installation and Maintenance
You won’t need to seek professional help to install the unit. It requires just basic DIY skills, but even if you are not that handy, it really won’t be an issue because it comes with JG quick connect fitting which allows for easy tubing connection.
The installation manual is comprehensive and straightforward with everything you need to set it up included in the package.
However, the filters in housing may be somewhat difficult to replace compared to the modular filters. The good thing though is that they are super durable which means fewer change-outs.
The stages 1 to 3 prefilters need changing just one a year and the membrane and the post-carbon filter will go for 3 to 5 years before requiring replacement.
For anyone looking for high quality and a high output coupled with the lowest maintenance possible, the APEC RO-90 is a unit worth considering. It’s ideal for situations where the demand for filtered water is higher than average.
