Continue to enjoy cleaner and safer water from your under-sink PUN4RO reverse osmosis water (RO) filtration system by using the VUN4ROKIT filter replacements.  This kit includes NSF certified filters with a universal design: one 5 micron sediment filter, one 5 micron carbon block filter and one granular activated polishing (GAC) filter. Together, these filters reduce particulates such as sand, rust and dirt, as well as reduce unwanted contaminants and chemicals, including chlorine taste and odor. Replace these filters every 6 months to maintain optimal filtration performance.
