Product review (1 stars): filter - 2stars,  customer service - 5 stars
This filter is aluminum mesh only.  No charcoal filter or any other material to help with odors or grease.  Basically, it will keep big chunks of gunk out of your fan and grease will stick on the mesh but not much else.  Please note - the filter is not what I expected but the bulk of that is my fault for not doing better research.  Due to M error, I have 24 of them that I will have to replace.  Next time, I'll do my research!

Customer service - I rate that at 5 stars.  I communicated prior to the sale, received prompt responses and the seller was very accommodating.  The seller shipped within 24 hours of my placing the order, it was well packed and he communicated with me after the sale.  Such stellar customer service is by far the exception within the online, impersonal buying experience.  I would patronize this seller again in a heartbeat.
