Air Filter 

 

The filter in the MOBI Crystal Breeze Air Purifier is made up of two parts -- a 
front prefilter for large dust particles and a filter box for small particles, odors, 
and harmful gases. The filter box includes a HEPA filter, activated carbon 
filter, and a multi-photocatalyst filter.
