It is an odd size that fits my furnace.

I’ve ordered three times now, always fast and competitively priced. Once I received the wrong size humidifier pads, I spoke to someone immediately and the order was corrected and sent out. Very good service! I am a retired light commercial mechanical contractor and I do recommend this company. I don’t care for Discount in there name because it applies to less than.

As with everything else that is going on, I notice the quality in everything is going down. If the product doesn’t last as long so they can sell more. Nothing last anymore.
