The BIG F PRO 256 is ideal for whole-house systems requiring higher flow capacity—handling up to 70 LPM at a UV dose of 30 mJ/cm². Pre-filtration ensures sediment is removed before UV exposure, enhancing disinfection by reducing light obstruction. The UV chamber then inactivates 99.9% of bacteria, protozoa (like Giardia and Cryptosporidium), and viruses.
