Product review (4 stars): They Work As Advertised.
This filter was for my Honeywell humidifier.. The filters are the same dimension and fit well. Noted that the filters do not have the "button" that the OEM filters had. Also they have a different make up.  No black plastic webbing, it is replaced by a different type of soft absorbent material.
it appears that these are some of the older filters that were OEM some years ago..  One clue was that the pack had a coupon inserted that expired in 2014...
Never the less the filters fit well, appear to be working as they should and were delivered quickly at a decent price.  Who could ask for anything more???
