Product review (3 stars): Ok... I guess
I ordered these filters for my humidifier because last time I bought the knock-off brand filters and they only lasted a very short period of time. My humidifier takes two of these filters at once... the first thing that disappointed me was receiving 3 filters... I for some reason assumed this listing meant you receive a 3-pack as in "3 replacements worth"... but I was wrong, you actually get 3 filters when you buy this. For me, this is dumb, because my humidifier takes two of them, so I'm left with an extra filter... now I have to buy another 3-pack to make it even.

The other thing that is a little weird is that this seller "cd_cellar4" doesn't include the original packaging when they ship these filters, you just get 3 filters stuck in an envelope, so there's no definitive way to be sure you received true Bionaire-brand filters, and not another knock-off brand. And, the postage they paid to ship the filters is clearly marked as $1.90 on the package, even though you get charged $4.49.
