Description
xRefresh your Medify MA-40 air purifier with the Midiex MA-40 replacement filter set. This 2-pack fits MA40W and MA40B models and delivers a 3-in-1 filtration solution that combines a high-efficiency HEPA layer with activated carbon to help manage common indoor pollutants.
Designed for MA-40 compatibility
These filters are built to plug directly into the MA-40 family, offering an easy swap that supports consistent airflow and performance. The combination of filter media targets fine particles while addressing odors through carbon media.
