Easy to setup - Easy to use
Ultrasonic Humidifier This unit is wonderfully easy to set up. The unit consists of three parts: a base, the water chamber, and a rotatable cap to direct the mist in the direction of your choosing. The unit will hold up to a half gallon of water. The manufacturer recommends distilled water but tap water can be used. If you have your own water filter on your sink or pitcher I would use that. Tap water can produce “scaling” - the “white dust” which is the product of minerals in the tap water. No problem if the “white dust” does occur – because cleaning is simple using just water (no chemicals or detergents of any kind). A small brush might come in handy. A more complete guide to cleaning came be found in the owners manual. So, you have the unit put together and added water so you are set to go: simply push the on and off button once and the unit will start. There are three positions – Low, Medium, and High. Push the button twice and you are on Medium – three times you are in High position. One more time and the unit turns itself off. The unit can run up to thirty hours at the Low setting. Set it and forget it. There is an automatic shutoff when the water level gets too low. The power button lights up “green” when the unit is running. The light turns “red” when it stops. And here is the very best benefit from this unit – it is absolutely quiet. I have been using this for several nights now and I still can't believe how quiet it is. Adding moisture to the air helps improve my breathing at night and ease allergies. I heartily recommend this humidifier.
A little Misleading
I really like this product. It is everything I have wanted in a humidifier. It is easy to set up, easy to fill. The water reserve has an easy open cap that allows you to fill it. It doesn't leak very much at all when you turn it up right to place it on the base and it fits easily on the base. It has a night light in the base that lights up the water reserve, which is perfect for a child's room or an elderly person whom you need or want to keep an eye on. The night light is also optional, you don't have to use it. The humidifier has three settings. You push the on button on the front and it turns it on low, push again you are on medium and a third time your on high. The fourth time will turn it off. It gives off a soft mist out the top which you can position so the mist sprays which every way you want it to blow. Now the three settings is where the misleading part comes in. The box and instructions state this is a .5 gallon humidifier and that it will last 30 hours. That is not necessarily true. It likely will last 30 hours if you place it on the low setting. However, if you put it on the high setting, which is what I prefer, it won't even last the night. I turned it on at 10:30pm on high. I woke up at 4 am and the power light, which is green when the humidifier is running, was red, indicating it had run out of water and shut itself off. I still would recommend this as it is a good product, but if you want it to last all night you will have to leave it on low.
A great little humidifier
Thisis an Ultrasonic Humidifierby Puraguardian It has a half gallon tank and lasts for about 30 hours It has low to high cool mist settings Has an on/ off night light It is treated with Silver Clean which is embedded in the tank to fight the growth of mildew and mold on the surface of the water tank It is ultra-quiet, which is perfect for a bedroom It is ultra-quick, it immediately begins to give off a fine even mist. It is ultra easy in that it has no filters It has a directional mist nozzle, a refill light indicator and shuts off automatically when empty I have a hard time holding things so this being only a half gallon tank works good for me. It realy helps at night in my bedroom, because it is so dry, I wake up coughing, but having this in there has realy helped I would highly recommend it to anyone who has a dryness problem in their home I would recommend getting a humidity reader to keep track of the levels You can get them at Walmart for a couple of dollars You can get this humidifier at Walmart for $38.44, which I think is a good price
