Tankless RO System

1st Stage
The first stage of the APEC ROTL-A1000 works hard to capture dirt, rust, and other visible particles before they reach your drinking water. This high-capacity sediment filter extends the life of the system while protecting the more delicate filtration stages that follow.


2nd Stage
In the second stage, our premium activated carbon block targets chlorine, volatile organic compounds, and unpleasant tastes or odors. This essential step enhances water flavor while safeguarding the RO membrane from chemical damage. Every sip tastes cleaner, fresher, and more refreshing — perfect for drinking, cooking, and brewing coffee or tea.

3rd Stage
The heart of the APEC ROTL-A1000 is its advanced reverse osmosis membrane, which removes up to 99.9% of contaminants including lead, arsenic, chromium, PFAS, and more. Certified to NSF 58 standards, this stage ensures you’re left with water that meets the highest purity benchmarks. Whether you’re filling a glass or cooking a family meal, you can trust the water is truly clean.
