Point-of-Use Water Filter Technology

Where are point-of-use (POU) water filters (tap filter, shower filter) typically used?

 

Point-of-use water filters can be used as an additional control measure in areas where immunocompromised people may come into contact with water (61-85), as outbreak and critical contamination solutions as an aid in reducing patient exposure. They can be easily installed at faucets (tap filters) or connected to shower hoses (shower filters). In medical facilities the most common areas for POU water filter installation are bone marrow transplant units, hematology/oncology units, ICUs, transplantation units, burn units, neonatology, endoscopic reprocessing, birthing pools, kitchen (for food preparation and drinking water provision), and geriatric departments. POU water filtration is also increasingly used in nursing homes long term care, or home care settings POU filters are quickly installed which makes them an effective and immediate management tool in acute water contamination situations.

What are the user requirements for POU water filtration?

 

User facilities typically ask for POU filtration designed to deliver water quality in accordance with international standards for sterilizing grade filtration (complete retention of ≥107 CFU Brevundimonas diminuta/cm2 effective filtration area) (87-90). End point filters are mostly used in humid environments, and the risk of contamination of the filter housing exists through backsplash. In order to minimize this risk of retrograde contamination, Pall POU water filters contain anti-retrograde contamination technologies. Hygienic performance of these POU filters has been demonstrated through laboratory validation, multicentre field evaluations, and independent clinical studies demonstrating robust performance over the full product lifetime (61-85).
