Review on 🌬️ LifeSupplyUSA Humidifier Filter Water Panel Pad Compatible with Aprilaire Furnace Models 400, 400A, and 400M – Compare to Aprilaire Part # 45 by Paul Zimmer

UPDATE: This initially seemed like a normal product but when it came time to replace the plate I opened up the humidifier and found that the innards of the Plate had slid down and only sat on the plate below in a drop. I don't know how long it's been like this. I usually use these plates twice as long as I should (turn them over when it's time to replace them). This didn't even last 1 full cycle. ORIGINAL REVIEW: Worked well but the corners were beat up. I just sent it wrapped in shrink wrap. The corners were slightly worn. Aligning them is fairly easy. After that it worked fine.
