If you are searching for a countertop system that’s ideal for homes with low pH, then this is an option you should check out.
The model comes in two versions, the RO-CTOP-PH and the RO-CTOP-PHC. The difference between the two is that the cartridges of RO-CTOP-PHC come with casing while the ones in the RO-CTOP-PH are exposed. Our review below is based on the RO-CTOP-PH.
The 1st stage is made up of a polypropylene sediment filter which removes dirt, sand, rust and all larger impurities in the water down to 5 microns.
The 2nd stage is equipped with an efficient coconut shell carbon filter that captures chlorine, chloramines, VOCs and common chemicals that cause unpleasant taste and odor. It also helps to further trap smaller sediments and remove color and cloudiness.
In the 3rd stage, we have the 0.0001-micron FILMTEC RO membrane where up to 99% of all TDS and remaining contaminants like fluoride, bacteria, viruses and heavy metals such as lead and arsenic are totally removed from the water.
The 4th and last stage in the RO-CTOP-PH system is a food-grade calcite mineral cartridge. This filter adds calcium carbonate into the water which introduces calcium minerals that neutralize the acidity of the RO water and raise its pH level. The resulting water has a more balanced alkalinity and a much pleasant, natural taste.
Despite being a compact, countertop RO system, this APEC RO-CTOP-PH model offers a high water output. It’s capable of generating 90 gallons of pure water per day making one of the best countertop RO systems for those with high water consumption.
Installation and Maintenance
Considering that it’s designed to stay on a countertop, the installation of the RO-CTOP-PH is a simple, straightforward process. The four filter cartridges come already assembled on a base. You only need to hook it to your faucet and you are done.
The unit is compact measuring 14 x 6.5 x 6 inches. Therefore it won’t take up much space on your countertop and it weighs just around 10 pounds making it really portable. You can even carry it if you travel a lot and want to keep your water fresh and clean.
The only downside to this particular version is that the filter cartridges are exposed which may not look presentable. However, if you prefer the casing, you can go for the RO-CTOP-PHC which comes with casing.
It’s also worth noting that the unit is compatible with standard faucets only. It will not work with any off-size designer faucet, sprayer or pull-out taps.
