Proven Performance in APEC's ULTIMATE RO Systems
APEC's ULTIMATE RO-CTOP-PH reverse osmosis system was engineered to the highest standards for exceptional performance, durability and safety. Constructed of select premium components while adding calcium minerals for people who prefer mineral water. This portable system guarantees the highest contaminant removal rates, giving you the purest water possible. This system's mineral cartridge adds only 100% US-made high-purity calcium carbonate to effectively raise pH in the water for those who desire alkaline water. Other re-mineralization RO systems will claim to add various beneficial minerals back into the water; however, their mineral formulations are often from unknown and uncertified sources that can lead to potential health concern. We build, inspect and lab test every ULTIMATE RO-CTOP-PH system in our US facility. This stringent QC process eliminates even the slightest component imperfections to guarantee a system that removes up to 99% of all contaminants and is completely free from water leaks, bursts and noises.
For over 20 years, APEC has been an industry leading manufacturer who specializes in high performance RO systems. As the original manufacturer, we have dedicated a knowledgeable and sincere team that is committed to providing customer satisfaction for the entire lifespan of every system.
Every APEC system is built to meet the most demanding applications in water purification - from drinking water for homes, to purified water for restaurants, healthcare facilities, and research labs. Our durable RO systems are designed to last for decades and will bring many years of enjoyment and good health for you and your family.
