Point-of-Use (POU) filtration can play an important role in secondary disinfection by providing final-stage protection at the locations where water is used—such as sinks, showers, and medical equipment. Here’s why it’s so important:

  1. Protects the Most Critical Endpoints
    POU filters are installed directly at fixtures where users are exposed to water, ensuring that any remaining pathogens are removed right before use.
  2. Removes Pathogens Missed by Upstream Treatment
    POU filters offer a physical barrier at the final step, capturing any that bypass upstream treatment.
  3. Immediate Risk Reduction
    POU filtration provides instant protection without waiting for system-wide chemical or thermal disinfection to take effect.
  4. Supports High-Risk Use Cases
    Especially important in healthcare settings, long-term care facilities, dialysis and sterile processing, laboratories. These environments demand the highest level of water safety at critical touchpoints.
  5. Bypasses System Complexities
    POU filtration provides a practical and highly focused intervention where full system treatment may not be reliable or cost-effective.
  6. Customizable and Scalable
    Filters can be customized at each outlet to meet the risks that are present throughout the water system.
  7. Complements a Multi-Barrier Strategy
    POU filtration is not a standalone solution, but when integrated into a comprehensive water management plan, it reduces risk at the point of contact and provides assurance in mission-critical applications

Point of Use vs Point of Entry Filtration

Point of use and point of entry filtration can both be important components of a comprehensive secondary disinfection process. Both of these filtration types have different types of roles. Above we described how point of use filtration is about removing pathogens at the source and offers mission critical protection at the source. Point of entry filtration involves removing pathogens at the point where water enters your facility. Point of entry is often the first line of defense against pathogens and also removes organic material, which makes disinfectants significantly more efficient.
