Customer Reviews
Ultrasonic Humidifier Replacement Demineralization Cartridges (4-Pack) is rated 4.7 out of 5 by 133.
Rated 3 out of 5 by from Good humidifier - design could be better I really like the humidifier. It certainly does the job for a medium sized room. However, the water tank is poorly designed though and can be hard to refill. The top of the tank is round and have to turn it upside down. Since its round you can rest it while It's filling up and it gets heavier and heavier for me to hold with one hand while the other had has to remain free to turn off the faucet in the tub when It's full. The kids have dropped it a few times. It made a mess but did not break yet. It also gets quite moldy but perhaps they all do. That being said, I have three of them for the bedrooms and they definitely help in the winter when the forced air heat is going.

Rated 4 out of 5 by from I think they workҐЏ? The shipping was amazingly fast, I received in just two days. They were as discribed and came with easy instructions. I'm not sure if they actually work though, I still see some mineral buildup in my humidifier. I don't want to test it without using them, just to see the difference... My only suggestion is if somehow they can make them MORE efficient in removing the minerals out of hard water, also how do you know when they go bad? They should turn a special color or something, when they go bad. Just putting that out there.

Rated 5 out of 5 by from Works great I live in a desert city and we have very hard water with lots of chemicals in it. I was worried about my humidifier breaking down due to such hard water. I bought these and they work great. You just toss one into the water tank and it takes the chemicals out of the water. No white residue build on the components of the machine. Plus they last for about 3 months per cartridge. I will definitely continue to purchase more.

Rated 5 out of 5 by from Ultrasonic humidifier We bought the humidifier about 6 weeks ago at Lowes and are very pleased with it. The demineralization cartridges work quite well. My only complaint is that Lowes didn_ґи__t carry the replacement cartridges. Ordering them was easy and they arrived in the mail in a timely manner. So far we are satisfied with the product.

Rated 5 out of 5 by from Love this little humidifier This small one-room humidifier has really improved my comfort level - and the performance of my houseplants & orchids, along the way. I've had other, larger, hardware and its heavy to carry. This one is small enough but indeed lives up to its promise. It lasts a good 24 hours or more. It's very quiet. And not too heavy when full of water. I bought extra little water softener bullets. But I've been using it every day and it doesn't send out white flakes and I have hard water. Anyhow, I live in a small space;. Every room is separate. So I just move it to one room per day. My eyes and my skin are not all dried up overnight, as happens every winter when the heat comes on. It's probably a "personal" product, sort of like a smartphone. It should not be asked to perform in large open spaces. But for a bedroom humidifier this is the best one I know.

Rated 5 out of 5 by from Ease of ordering and a word about your website I received excellent customer service from your HoMedic phone representative. I went on line to get the particulars of the device listed above but could no order on line. This was just as well as I don't like to do that anyway. Thank you for your very comprehensive web site, and thank you for your phone repes! My humidifier works very well and now I have a sufficient supply of demineralizers to keep it that way!

Rated 3 out of 5 by from HoMedics Humidifier 1. Easy to fill 2. Nice modern design 3. After a week of constant use, raised the humidity level from 18% to 48%. I bought 2 and they are both running. 4. I have a water softener in my home. Water softeners remove minerals from water. Using the mineral filters that came with these units, I still get a white dust that coats the furniture and wood floors.

Rated 5 out of 5 by from Homedics Replacement Cartridges My wife and I recently purchased 2 of your humidifiers with the above-mentioned cartridges. We FINALLY have been having good luck with not only the humidifiers, but also with the cartridges. The cartridges do a VERY EFFECTIVE JOB in keeping the components clean and operable.

how does this work in a uhe-oc1 humidifier? The cartridge is round in the uhe-oc1.

Asked by: bob mele
This Cartridge may look different than the one that came with your unit; the white Cartridges are being phased out in favor of the blue capsule. This Cartridge works with all of our Ultrasonic Humidifiers. To use it, you just drop it in the water tank.

Would you please email me when you have your demineralization cartridges in stock?

does Target carry your demineralization cartridges

Asked by: Robrta

These are different from what I used to buy. My previous ones were round like a donut shape and went under the water tank. Do these new ones go directly in where the water goes?
