Bluonics 4.5 x 20 Whole House Carbon Filters 6 PK For Big Blue Water Filter

My filter housing broke in the AZ heat, so I decided to go a different direction…. My loss is your gain. These are brand new, still in factory plastic. 6 Bluonics carbon block filters, 4.5″ X 20″, fit Big Blue plus other housings – check for fitment before ordering.
