Review on 🏡 Aprilaire 400M Whole Home Humidifier, Manual Water-Saving Furnace Humidifier, High-Capacity Whole House Humidifier for Homes up to 4,000 Sq. Ft., in White by Stephanie Martel

So they are not telling you that this product is not recommended for high efficiency stoves. (I spoke to the company's customer service, they have no way of getting my money back as they didn't sell me the unit. I ended up buying a 600M and it works great.) I recently had my oven repaired after one This unit was in place within 3 months and this design brought the technology back completely. They told me to replace this device with a traditional humidifier that constantly lets water through while the heater is on. On a high power oven they only run for a short time and this unit fills up too quickly and shuts off the water which doesn't allow much moisture to escape. Would recommend unless you have a high efficiency stove where no drain is available.
