What is the Nexxus System?
The Nexxus by Oasis Water Technologies is a compact whole-home point-of-entry (PoE) water filtration system that treats water as it enters your home.
By filtering water at the main water line, Nexxus helps ensure every faucet, shower, and appliance receives cleaner water.
Unlike traditional multi-tank filtration systems, the Nexxus uses high-performance carbon block filtration and real-time monitoring technology to deliver powerful filtration in a compact design.
How the Nexxus Works
The Nexxus system filters water before it enters your home’s plumbing system.
Water passes through multiple filtration stages designed to reduce common contaminants such as:
• Sediment (sand, rust, and debris)
• Chlorine and chloramines
• Lead
• PFAS compounds such as PFOA and PFOS
• Volatile organic compounds (VOCs)
Because filtration occurs at the point where water enters the home, Nexxus helps provide consistent water quality throughout the entire house.
This means the water used for drinking, cooking, showering, and laundry is all treated before it reaches your taps.
Smart Monitoring with the Nexxus App
The Nexxus system includes real-time monitoring technology designed to help users understand and maintain their filtration system.
Built-in pressure sensors communicate with the Oasis Core™ processor, which sends system data to the Nexxus mobile app.
This allows users to:
• Monitor system performance
• Track filter usage
• Receive notifications when filters should be replaced
Instead of relying on generic replacement schedules, the Nexxus evaluates actual filter performance and water conditions.
Why Point-of-Entry Filtration Matters
Point-of-entry filtration treats water before it reaches your home’s plumbing system.
This ensures that every faucet and appliance receives treated water, rather than filtering water at a single tap.
Unlike many reverse osmosis systems, whole-home filtration systems like Nexxus:
• Maintain strong household water pressure
• Support high household flow rates
• Produce zero wastewater
This makes point-of-entry filtration a practical solution for treating water across an entire home.
Compact Design
Many traditional whole-home filtration systems rely on large tanks that require significant installation space.
The Nexxus system was engineered to deliver whole-home filtration in a compact footprint, making installation easier while still supporting the flow rates needed for modern homes.
Local Water Intelligence
The Nexxus ecosystem also includes The Grid by Oasis Water Technologies.
By entering a zip code on the Oasis Water Technologies website or Nexxus app, users can view recent water quality data for their local municipality.
This information is sourced from the EPA ECHO database, helping customers better understand the contaminants that may be present in their local water supply.
This data can also help determine which filter pack configuration is best suited for a particular area.
Automated Filter Replacement (Delta Plan)
Customers enrolled in the Oasis Delta Plan can receive replacement filters automatically.
The system analyzes filter performance and local water conditions to determine when replacement filters are needed.
When a replacement is required, the appropriate filter pack is shipped directly to the customer.
