Product review (3 stars): Buyer beware...
My wife bought five of these filters recently from Dealyard. We received all five filters from them, but only two of them had the air filter feature that is listed in the item description. The other three must have been a much older version which will function as a humidifier filter but will do nothing to filter the air, similar to the original Holmes replacement filter. They all had the same part number (HC-14) listed on the box, but the two boxes are totally different.

Previously, we have bought these filters directly from Amazon and they have all included the air filter element, which we like. Needless to say, we were mildly disappointed.

Dealyard is known as a clearance item retailer, so who knows how old these filters are? Be warned: if you buy from Dealyard you may not receive what you are expecting.
