Product review (4 stars): Actually appear to be genuine Vornado brand product.
The crap water in DC clogs these in a few weeks, but these appear to be the legit, genuine Vornado brand product.  The box looks the same, the filters look the same and are the same size.  They come in a plastic inner liner bag, just like the Bed, Bath, & Beyond-purchased ones.  "(2-pack)" means one box containing two filters, so that's enough to replace to the two filters in the humidifier once.  It is not two boxes containing four filters.
