furnace humidifier by Michael Philbrick ( )

Fit fine. Is doing the job it was designed to do. Installed personally (homeowner) with no special tools besides what should be in a homeowner's toolkit. A few issues with keeping water from leaking probably because of the pump motor plastic housing being worn, but after drip stopped haven't check for weeks.

Atta Kid by Kevin (Eldridge MO US)

Humidifier hadn't been used in years, so I disassembled everything, cleaned it up, threw in a new evaporator pad and orifice and the thing works perfect. Thanks for making this project simple with in stock, OEM parts that arrived on my doorstep in a timely manner. Other sites had the same items for cheaper but long backorder dates and pathetic customer service. First time customer and soon-to-be repeat customer. Thanks again.

good stuff by Jim Gaskell (Chanute KS US)

I ordered the orifice and Strainer assemby to replace the ones that have been on my humidifier and furnace for about 13 years. The parts were exactly as my original ones. I installed the parts and they worked just like it was when I first installed my furnace. I appreciated the delivery as promised and will continue to do business with this company.

Very smooth transaction!! by Edward Meyer (Buffalo Grove Il US)

This part had become clogged and I could not find it locally anywhere. I then did a search to find the part on-line and was delighted to find the exact O.E.M. part available at a reasonable cost. I ordered two units (one for a spare) and they were shipped promptly via U.P.S. I was kept informed of the shipment progress and the carton was delivered exactly when it was scheduled. This transaction could not have gone smoother, the parts are O.E.M. originals and our humidifier is now working just fine. Thanks for such a pleasant purchasing experience!
