Yes, possibly too good to be true, it seems that the product is either a factory second or a new unused item with defects, also, as far as I can tell it only filters 95.6% of the particles as small as 0.3µm, you really want one that filters 99.99%@ 0.3µm.
I don't see anything in the description about it being 99.99% efficient @ 0.3µm

"Efficiency: 95%, 99.97% and 99.99% at 0.3µ."

Yes, that means there are three different models with those efficiency ratings, if the one you got is the one pictured then it is at 95.6%@0.3µm.

Well, yes but I suspect it depends on the standards that it was tested under, there are several classes of HEPA filters, I would say your's is an E11 whereas you really want an H14 or higher.
That data doesn't mention what class it is, is it an E11?

It should have a letter, E,H or U with a number after it, you want an H14.
