Product review (5 stars): Received Genuine Authentic OEM Aprilaire Product
I was already ordering a 2 pack of OEM Aprilaire 35 water panels from Amazon, then stumbled on this.  I thought surely for only a couple dollars each they must be junk, but decided to order one on a whim in hopes that it might be at least somewhat similar quality to the Aprilaire.  Today the package arrived, to my amazement, not only was it similar quality to the OEM ... it WAS an OEM Aprilaire in OEM packaging and identical to the 2 pack of filters I bought for more expensive ...  See the picture below, the water panel I received from FiltersNow wasn't a generic knock off or "aftermarket" as the listing said, it was the real deal.

I have never been so pleased to have an inaccurate listing.  I will absolutely be buying this again
