Space-gard And Aprilaire #4330 Aprilaire Scale Control Insert

This unit was advertised as the correct size as a replacement part for my Aprilaire humidifier. It does not fit! I am using my old unit with a new replacement water panel. I've contacted this supplier by email and asked for the appropriate information so that I can invoke their somewhat cumbersome return policy. I am waiting for their reply. Would not recommend buying this unit since it does not fit the Model size it professes to fit.

No issues at all with this in my old Aprilaire 600 unit. Looks and fits the same as the original.

I bought this as a replacement for my Aprilaire model 760. I bought with a filter and the scale filter as a kit. The filter did fit but the insert and tray did not. I went on again and see it now listed for Aprilaire 600. I am not sure if this was a mistake or not. This part came up as a suggested item when I purchased the filter so it may be linked to the filter by mistake. At any rate, I await a reply and will update if they send the right parts. As for the filter, it works great. The old insert was not defective, just a little dirty. I'd still replace it because it's original and the unit is old...but it works.
