Overview
At just 0.71 lb, the Maxblue MB-F11B is a compact replacement filter cartridge certified to NSF 42/372, measuring roughly 3.15 x 3.15 x 6.22 inches.
No seller description is published for this listing, so the review draws only from the certification and size data. NSF 42/372 covers aesthetic effects like chlorine taste and odor plus lead-free material compliance, a narrower scope than filters tested against a broader contaminant list.
