Query: But are they HEPA filters?

I ordered two from Amazon, and received them in apparently good condition from another vendor. They look like the picture on line and fit the machine. But the box said nothing about Honeywell, and there was no packing slip. The product says nothing on it about Honeywell and has no part number or other identifier on it. In the past I have ordered Honeywell pre-filters on Amazon, and been sent generics. The pre-filters were clearly different products and lots of people were complaining in Amazon reviews. These filters I just received could be Hepa filters, or folded coffee filters in frames. Honeywell -- and Amazon -- should be after these guys.
