I need a what??

So…. I moved to NC from Florida about 8 months ago. A few weeks ago I caught a virus. I was absolutely miserable for over a week. The only time I ever had anything hang on so long was COVID, but this wasn't it. I called my doctor and she said I needed a humidifier. I had heard of them, but having lived in hot, humid Florida most of my life, never really thought people actually used them. Until now. So, I purchased this off another site for $10 more but faster delivery. My head and chest started clearing up after the first night. So yeah, this is a necessity in NC. After using the other one for a few weeks, I bought this one here. They work very well, have 3 different vapor settings, and the light inside looks great in my living room. They also clean up very easily. I read how other reviewers had issues with theirs leaking, but mine haven't. There is some water in the base when you take the tank off, but that's to be expected since that's where the water is turned into vapor. There isn't anything there that the water can damage though. It's also easy to just wipe it out so that no mold or mildew grows there. I personally am very happy with this humidifier and highly recommend it.

Gallon humidifyer.

My wife and I love this humidafyer . our room at the nursing home is very dry. My wife has breathing issues. It delivers the perfect amount of humid air required for us to breath. It is very quiet too. And the size is perfect for our room. We are very pleased with this product and recommend it to anyone looking for one. It also has a night light we just discovered.

best with filtered or distilled water.

I didn't see it in the description, but the instructions said you should use distilled or filtered water to avoid dust from the minerals in the water. I was lucky enough to have a source of filtered water. If I didn't, the expense of using distilled or filtered water or having mineral dust would have made me much less likely to get this. Other than this, it is very quiet and easy to use. I haven't tried using essential oils (I have had humidifiers before and have never used that)
