Product review (3 stars): Call Bionaire Directly
If you have a Bionaire console humidifier, you need these wicks, which should be replaced roughly every two months.

But as much as I enjoy using Amazon (been a Prime member for years), this is not the product to purchase from Amazon.  Call Bionaire directly.  Instead of complaining about getting a non-Bionaire replacement, you'll get the genuine product, often for less.  As I write this, they are having a 40% off sale on filters -- filters <$8, wicks <$10 per pair -- and free shipping on orders over $25.

NOTA BENE: Bionaire no longer includes the plastic frames with the wicks, either, SO KEEP YOUR FRAMES!  Also, they sell the wicks as a single item, not a twin pack, so for my W-9 I needed to order in pairs.
