Not Honeywell as implied in listing.
These sub standard filters arrived badly bent.  Vendor quickly issued a refund - but I probably would have returned them even if not damaged. They are no where the density of the OEM filters, you can literally clearly see through them. I invested too much money in my top of the line HVAC system to skimp on the filters.<br /><br />Now I have to find OEM filters elsewhere - the only OEM filters on Amazon are the post- filters.
