MEETOOT 2-Pack 20mm Ultrasonic Mist Maker Fogger Ceramics Discs with Wire and Sealing Ring

These fixed my diffuser. They are functionally identical to the one I replaced. Time will tell as to durability, but as of now they are a great value for the price.

Perfect fit for my Homedics model #1520272. The humidifier is a pain to take apart, to the point of replacing the Transducer, but repair is much cheaper than a new unit. PCB does not have a plugin connector for the wire harness. So you will need to cut and splice to the old wires or as I did, un-solder the old transducer wires and re-solder the new. The size and seal on the new transducer are an exact fit. Make sure you put water in the humidifier BEFORE plugging it in. Transducer failed originally because I did not do that. Dry transducer will burn the coating off or spit it as mine did.

Works great with Young Living rosebud diffuser, really pumps out the mist! However, the new silicone seal is not a tight fit... I re-used the original. I removed the wires from the plug & reversed them to keep polarity the same as original (don't know if it matters). Also, I don't know if the unit will shut off when water is gone like the original. If it doesn't & the disc gets damaged, I'll replace it again & not let water go dry again... beats paying over $16 for just one disc from Dr. diffuser!

Great Value. Bought to repair (2) Pureguardián H3250wca ultrasonic humidifiers which were left unattended for several months. I first did a complete cleaning, but they still would not mist. Thought I would replace the ultrasonic transducer. Since I was repairing 2 of these I decided to go with the 5 pack. I had measured the transducer and found they were 20mm and had a connector looking similar to mine, However, once I got them, I noticed the connector was slightly different. I thought I would unsolder the bad and resolder the good. That did not work for me. I did not have any flux so I think that is why the solder would not stick to the transducer. So I just cut the wires and put them together. Since the wires were different colors, I just picked 2 and put them together. It worked, so I just put the second one together the same way. I do not know if it makes a difference, or I got lucky. Bottom line: My 2 humidifiers work very well now, and I did not have to replace them (over $100 for each). I would have given 5 stars, but I did have to rewire a bit. At $8 for the 5 pack, it was a very good deal. I have only had them repaired for a day, but working awesome for now.

Had to change the connection pin to humidifier motherboard. I removed it and used one from the old one which was not working. Works as expected.

Does not work

Perfect replacement for my Homedics humidifier. Was a little bit of work getting the module but replacement worked perfect and I have plenty of spares.

I had high hopes but this just doesn’t work as well as the new humidifier’s ultrasonic transducer. When the humidifier was new it would dump a tank in 12 hours now it’s close to 36.
